+## Writing a new sample
+
+Write samples according to the [sample style guide](https://googlecloudplatform.github.io/samples-style-guide/).
+
+## Testing your code changes.
+
+### Install dependencies
+
+To run the tests in a samples directory, you will need to install
+[Composer](http://getcomposer.org/doc/00-intro.md).
+
+First install the testing dependencies which are shared across all samples:
+
+```
+composer install -d testing/
+```
+
+Next, install the dependencies for the individual sample you're testing:
+
+```
+SAMPLES_DIRECTORY=translate
+cd $SAMPLES_DIRECTORY
+composer install
+```
+
+### Environment variables
+Some tests require specific environment variables to run. PHPUnit will skip the tests
+if these environment variables are not found. Run `phpunit -v` for a message detailing
+which environment variables are missing. Then you can set those environment variables
+to run against any sample project as follows:
+
+```
+export GOOGLE_PROJECT_ID=YOUR_PROJECT_ID
+export GOOGLE_STORAGE_BUCKET=YOUR_BUCKET
+```
+
+If you have access to the Google Cloud Kokoro project, decrypt the
+`.kokoro/secrets.sh.enc` file and load those environment variables. Follow
+the instructions in [.kokoro/secrets-example.sh](.kokoro/secrets-example.sh).
+
+If your tests require new environment variables, you can set them up in
+`.kokoro/secrets.sh.enc` so they pass on Kokoro. For instructions on managing those
+variables, view [.kokoro/secrets-example.sh](.kokoro/secrets-example.sh) for more
+information.
+
+### Run the tests
+
+Once the dependencies are installed and the environment variables set, you can run the
+tests in a samples directory.
+```
+cd $SAMPLES_DIRECTORY
+# Execute the "phpunit" installed for the shared dependencies
+PATH_TO_REPO=/path/to/php-docs-samples
+$PATH_TO_REPO/testing/vendor/bin/phpunit
+```
+
+Use `phpunit -v` to get a more detailed output if there are errors.
+
 ## Style
 
-Samples in this repository follow the [PSR2][psr2] and [PSR4][psr4]
-recommendations. This is enforced using [PHP CS Fixer][php-cs-fixer].
+The [Google Cloud Samples Style Guide][style-guide] is considered the primary
+guidelines for all Google Cloud samples. 
+
+[style-guide]: https://googlecloudplatform.github.io/samples-style-guide/
+
+Samples in this repository also follow the [PSR2][psr2] and [PSR4][psr4]
+recommendations. This is enforced using [PHP CS Fixer][php-cs-fixer], using the config in [.php-cs-fixer.dist.php](.php-cs-fixer.dist.php)
+
+Install that by running
+
+```
+composer global require friendsofphp/php-cs-fixer
+```
+
+Then to fix your directory or file run
+
+```
+php-cs-fixer fix . --config .php-cs-fixer.dist.php
+php-cs-fixer fix path/to/file --config .php-cs-fixer.dist.php
+```
+
+The [DLP snippets](https://github.com/GoogleCloudPlatform/php-docs-samples/tree/main/dlp) are an example of snippets following the latest style guidelines.

+    $ export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credentials.json
+```
+3.  **Clone the repo** and cd into this directory
+```sh
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/analyticsdata
+```
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+5.  **Replace `$property_id` variable** if present in the snippet with the
+value of the Google Analytics 4 property id you want to access.
+6.  **Run** with the command `php SNIPPET_NAME.php`. For example:
+```sh
+    $ php quickstart.php
+```

+
+Please familiarize yourself with the OAuth2 flow guide at
+https://developers.google.com/identity/protocols/oauth2
+
+For more information on authenticating as an end user, see
+https://cloud.google.com/docs/authentication/end-user
+
+In a nutshell, you need to:
+
+1. Create your OAuth2 client credentials in Google Cloud Console.
+Choose "Web application" when asked for an application type.
+https://support.google.com/cloud/answer/6158849
+
+2. When configuring the web application credentials, add
+"http://localhost:3000/" to "Authorized redirect URIs".
+
+3. Download a credentials file using "Download JSON" button in the credentials
+configuration dialog and save it as `oauth2.keys.json` in the same
+directory with this sample app.
+
+4. Replace `$property_id` variable with the value of the Google Analytics 4
+property id you want to access.
+
+5. Install the PHP bcmath extension (due to https://github.com/protocolbuffers/protobuf/issues/4465):
+
+    ```
+    sudo -s apt-get install php-bcmath
+    ```
+
+6. Run the following commands from the current directory in order to install
+dependencies and run the sample app:
+
+    ```
+    composer update
+    php -S localhost:3000 -t .
+    ```

-# Cloud SQL & Google App Engine Flexible Environment
-
-This sample application demonstrates how to use [Cloud SQL with Google App Engine Flexible Environment](https://cloud.google.com/appengine/docs/flexible/php/using-cloud-sql).
-
-## Setup
-
-Before running this sample:
-
-## Prerequisites
-
-- Install [`composer`](https://getcomposer.org)
-- Install dependencies by running:
-
-```sh
-composer install
-```
-
-## Setup
-
-Before you can run or deploy the sample, you will need to do the following:
-
-1. Create a [Second Generation Cloud SQL](https://cloud.google.com/sql/docs/create-instance) instance. You can do this from the [Cloud Console](https://console.developers.google.com) or via the [Cloud SDK](https://cloud.google.com/sdk). To create it via the SDK use the following command:
-
-        $ gcloud beta sql instances create YOUR_INSTANCE_NAME --tier=db-f1-micro --activation-policy=ALWAYS
-
-	> Note: the `--tier` option is required to create a `Second Generation` instance. See the
-	  full list of available tiers by running `gcloud sql tiers list`
-
-2. Set the root password on your Cloud SQL instance:
-
-        $ gcloud sql instances set-root-password YOUR_INSTANCE_NAME --password YOUR_INSTANCE_ROOT_PASSWORD
-
-3. Install and run the [CloudSQL Proxy](https://cloud.google.com/sql/docs/mysql-connect-proxy)
-
-4. Create a database for this example
-
-        $ mysql -h 127.0.0.1 -u root -p -e "CREATE DATABASE <YOUR_DATABASE_NAME>;"
-
-## Deploy to App Engine
-
-**Prerequisites**
-
-- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
-
-**Deploy with gcloud**
-
-1. Update `app.yaml` with the configuration values for `USER`, `PASSWORD`, and
-   `DATABASE` with the values you used during setup.
-
-1. Get the CloudSQL connection name
-
-    $ gcloud beta sql instances describe YOUR_INSTANCE_NAME | grep connectionName
-
-1. Update `app.yaml` with the configuration value for `CONNECTION_NAME` you retrieved
-   at the end up setup.
-
-```
-gcloud config set project YOUR_PROJECT_ID
-gcloud app deploy
-gcloud app browse
-```
-
-The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
-in your browser.
-
-## Run locally
-
-1.  Ensure the [CloudSQL Proxy](https://cloud.google.com/sql/docs/external#proxy) is
-    installed and running.
-
-1.  Set the following environment variables with the configuration values for
-    `USER`, `PASSWORD`, `DATABASE`, and `CONNECTION_NAME` you used during setup:
-
-    ```sh
-    # set local mysql connection parameters
-    export MYSQL_DSN="mysql:host=127.0.0.1;port=3306;dbname=DATABASE"
-    export MYSQL_USER=USER
-    export MYSQL_PASSWORD=PASSWORD
-    ```
-
-1.  Run the application
-
-    ```sh
-    cd php-docs-samples/appengine/flexible/cloudsql
-    php -S localhost:8080
-    ```
-
-Now you can view the app running at [http://localhost:8080](http://localhost:8080)
-in your browser.

-# Cloud SQL & Google App Engine Flexible Environment
-
-This sample application demonstrates how to use [Cloud SQL with Google App Engine Flexible Environment](https://cloud.google.com/appengine/docs/flexible/php/using-cloud-sql).
-
-## Setup
-
-Before running this sample:
-
-## Prerequisites
-
-- Install [`composer`](https://getcomposer.org)
-- Install dependencies by running:
-
-```sh
-composer install
-```
-
-## Setup
-
-Before you can run or deploy the sample, you will need to do the following:
-
-1. Create a [Second Generation Cloud SQL](https://cloud.google.com/sql/docs/create-instance) instance. You can do this from the [Cloud Console](https://console.developers.google.com) or via the [Cloud SDK](https://cloud.google.com/sdk). To create it via the SDK use the following command:
-
-        $ gcloud beta sql instances create YOUR_INSTANCE_NAME --tier=db-f1-micro --activation-policy=ALWAYS
-
-	> Note: the `--tier` option is required to create a `Second Generation` instance. See the
-	  full list of available tiers by running `gcloud sql tiers list`
-
-2. Set the root password on your Cloud SQL instance:
-
-        $ gcloud sql instances set-root-password YOUR_INSTANCE_NAME --password YOUR_INSTANCE_ROOT_PASSWORD
-
-3. Install and run the [CloudSQL Proxy](https://cloud.google.com/sql/docs/mysql-connect-proxy)
-
-4. Create a database for this example
-
-        $ mysql -h 127.0.0.1 -u root -p -e "CREATE DATABASE <YOUR_DATABASE_NAME>;"
-
-## Deploy to App Engine
-
-**Prerequisites**
-
-- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
-
-**Deploy with gcloud**
-
-1. Update `app.yaml` with the configuration values for `USER`, `PASSWORD`, and
-   `DATABASE` with the values you used during setup.
-
-1. Get the CloudSQL connection name
-
-    $ gcloud beta sql instances describe YOUR_INSTANCE_NAME | grep connectionName
-
-1. Update `app.yaml` with the configuration value for `CONNECTION_NAME` you retrieved
-   at the end up setup.
-
-```
-gcloud config set project YOUR_PROJECT_ID
-gcloud app deploy
-gcloud app browse
-```
-
-The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
-in your browser.
-
-## Run locally
-
-1.  Ensure the [CloudSQL Proxy](https://cloud.google.com/sql/docs/external#proxy) is
-    installed and running.
-
-1.  Set the following environment variables with the configuration values for
-    `USER`, `PASSWORD`, `DATABASE`, and `CONNECTION_NAME` you used during setup:
-
-    ```sh
-    # set local mysql connection parameters
-    export POSTGRES_DSN="pgsql:host=127.0.0.1;port=5432;dbname=DATABASE"
-    export POSTGRES_USER=USER
-    export POSTGRES_PASSWORD=PASSWORD
-    ```
-
-1.  Run the application
-
-    ```sh
-    cd php-docs-samples/appengine/flexible/cloudsql
-    php -S localhost:8080
-    ```
-
-Now you can view the app running at [http://localhost:8080](http://localhost:8080)
-in your browser.

-# Mailgun PHP Sample Application for App Engine Flexible Environment.
-
-## Description
-
-This sample application demonstrates how to use [Mailgun with Google App Engine](https://cloud.google.com/appengine/docs/php/mail/).
-
-## Setup
-
-Before running this sample:
-
-1. You will need a [Mailgun account](http://www.mailgun.com/google).
-2. Update `MAILGUN_DOMAIN` and `MAILGUN_APIKEY` in `index.php` to match your
-   Mailgun credentials. You can use your account's sandbox domain.
-
-## Prerequisites
-
-- Install [`composer`](https://getcomposer.org)
-- Install dependencies by running:
-
-```sh
-composer install
-```
-
-## Deploy to App Engine
-
-**Prerequisites**
-
-- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
-
-**Deploy with gcloud**
-
-```
-gcloud config set project YOUR_PROJECT_ID
-gcloud app deploy
-gcloud app browse
-```
-
-The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
-in your browser.
-
-## Run Locally
-
-```
-cd /path/to/php-docs-samples/appengine/flexible/mailgun
-php -S localhost:8080
-```
-
-Now browse to `http://localhost:8080` to view the sample.

-# Mailjet PHP Sample Application for App Engine Flexible Environment.
-
-## Description
-
-This sample application demonstrates how to use [Mailjet with Google App Engine](https://cloud.google.com/appengine/docs/php/mail/).
-
-## Setup
-
-Before running this sample:
-
-1. You will need a [Mailjet account](http://www.mailjet.com).
-2. Update `MAILJET_APIKEY` and `MAILJET_SECRET` in `index.php` to match your
-   Mailjet credentials.
-
-## Prerequisites
-
-- Install [`composer`](https://getcomposer.org)
-- Install dependencies by running:
-
-```sh
-composer install
-```
-
-## Deploy to App Engine
-
-**Prerequisites**
-
-- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
-
-**Deploy with gcloud**
-
-```
-gcloud config set project YOUR_PROJECT_ID
-gcloud app deploy
-gcloud app browse
-```
-
-The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
-in your browser.
-
-## Run locally
-
-you can run locally using PHP's built-in web server:
-
-```sh
-cd php-docs-samples/appengine/flexible/mailjet
-php -S localhost:8080
-```
-
-Now you can view the app running at [http://localhost:8080](http://localhost:8080)
-in your browser.

-# Sendgrid and Google App Engine Flexible Environment
-
-This sample application demonstrates how to use [Sendgrid with Google App Engine Flexible Environment](https://cloud.google.com/appengine/docs/flexible/php/sending-emails-with-sendgrid).
-
-## Setup
-
-Before running this sample:
-
-1. You will need a [SendGrid account](http://sendgrid.com/partner/google).
-2. Update `SENDGRID_SENDER` and `SENDGRID_API_KEY` in `app.yaml` to match your
-   SendGrid credentials. You can use your account's sandbox domain.
-
-## Prerequisites
-
-- Install [`composer`](https://getcomposer.org)
-- Install dependencies by running:
-
-```sh
-composer install
-```
-
-## Deploy to App Engine
-
-**Prerequisites**
-
-- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
-
-**Run Locally**
-```sh
-export SENDGRID_API_KEY=your-sendgrid-api-key
-export SENDGRID_SENDER=somebody@yourdomain.com
-php -S localhost:8000 -t .
-```
-
-**Deploy with gcloud**
-```
-gcloud config set project YOUR_PROJECT_ID
-gcloud app deploy
-gcloud app browse
-```
-
-The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
-in your browser.

+# PHP websockets sample for Google App Engine Flexible Environment
+
+This sample demonstrates how to use websockets on [Google App Engine Flexible Environment](https://cloud.google.com/appengine).
+
+## Running locally
+
+Use the following commands to run locally:
+
+    ```sh
+    cd php-docs-samples/appengine/flexible/websockets
+    php -S localhost:8080
+    ```
+
+## Deploying
+Refer to the [top-level README](../README.md) for instructions on running and deploying.
+
+**Important**: After you deploy to App Engine Flexible, you will need to request the page `/index.html` directly to access the sample (for example, `https://YOUR_VERSION-dot-YOUR_PROJECT_ID.uc.r.appspot.com/index.html`).
+
+You will also have to [create a firewall rule](https://cloud.google.com/sdk/gcloud/reference/compute/firewall-rules/create) that accepts traffic on port `8000`:
+
+	```sh
+	gcloud compute firewall-rules create allow-8000 --allow=tcp:8000 --target-tags=websockets-allow-8000
+	```

+# Run WordPress on App Engine Flexible
+
+This is a small command line tool for downloading and configuring
+WordPress for Google Cloud Platform. The script allows you to create a
+working WordPress project for the
+[App Engine flexible environment][appengine-flexible]. For deploying
+WordPress to the [App Engine standard environment][appengine-standard],
+refer to the example at [appengine/standard/wordpress](../../standard/wordpress)
+
+## Common Prerequisites
+
+* Install [Composer][composer]
+* Create a new Cloud Project using the [Cloud Console][cloud-console]
+* Enable Billing on that project
+* [Enable Cloud SQL API][cloud-sql-api-enable]
+* Install [Google Cloud SDK][gsubl ..cloud-sdk]
+* Install the [mysql-client][mysql-client] command line tool
+
+## Project preparation
+
+Configure Google Cloud SDK with your account and the appropriate project ID:
+
+```
+$ gcloud init
+```
+
+Create an App Engine application within your new project:
+
+```
+$ gcloud app create
+```
+
+Then configure the App Engine default GCS bucket for later use. The default App
+Engine bucket is named YOUR_PROJECT_ID.appspot.com. Change the default Access
+Control List (ACL) of that bucket as follows:
+
+```
+$ gsutil defacl ch -u AllUsers:R gs://YOUR_PROJECT_ID.appspot.com
+```
+
+### Create and configure a Cloud SQL for MySQL 2nd generation instance
+
+Note: In this guide, we use `wp` for various resource names; the instance
+name, the database name, and the user name.
+
+Create a new Cloud SQL for MySQL Second Generation instance with the following
+command:
+
+```
+$ gcloud sql instances create wp \
+  --activation-policy=ALWAYS \
+    --tier=db-n1-standard-1
+```
+
+Note: you can choose `db-f1-micro` or `db-g1-small` instead of
+`db-n1-standard-1` for the Cloud SQL machine type, especially for the
+development or testing purpose. However, those machine types are not
+recommended for production use and are not eligible for Cloud SQL SLA
+coverage. See our [Cloud SQL SLA](https://cloud.google.com/sql/sla)
+for more details.
+
+Then change the root password for your instance:
+
+```
+$ gcloud sql users set-password root --host=% \
+  --instance wp --password=YOUR_INSTANCE_ROOT_PASSWORD # Don't use this password!
+```
+
+To access this MySQL instance, use Cloud SQL Proxy. [Download][cloud-sql-proxy-download]
+it to your local computer and make it executable.
+
+Go to the [the Credentials section][credentials-section] of your project in the
+Console. Click 'Create credentials' and then click 'Service account key.' For
+the Service account, select 'App Engine app default service account.' Then
+click 'Create' to create and download the JSON service account key to your
+local machine. Save it to a safe place.
+
+Run the proxy by the following command:
+
+```
+$ cloud_sql_proxy \
+  -dir /tmp/cloudsql \
+    -instances=YOUR_PROJECT_ID:us-central1:wp=tcp:3306 \
+      -credential_file=PATH_TO_YOUR_SERVICE_ACCOUNT_JSON_FILE
+```
+
+Now you can access the Cloud SQL instance with the MySQL client in a separate
+command line tab. Create a new database and a user as follows:
+
+```
+$ mysql -h 127.0.0.1 -u root -p
+mysql> create database wp;
+mysql> create user 'wp'@'%' identified by 'PASSWORD'; // Don't use this password!
+mysql> grant all on wp.* to 'wp'@'%';
+mysql> exit
+```
+
+## How to use
+
+First install the dependencies in this directory as follows:
+
+```
+$ composer install
+```
+
+If it complains about extensions, please install `phar` and `zip` PHP
+extensions and retry.
+
+Then run the helper command.
+
+```
+$ php wordpress.php setup
+```
+
+The command asks you several questions, please answer them. Then you'll have a
+new WordPress project. By default it will create `my-wordpress-project` in the
+current directory.
+
+## Deployment
+
+CD into your WordPress project directory and run the following command to
+deploy:
+
+```
+$ cd my-wordpress-project
+$ gcloud app deploy \
+    --promote --stop-previous-version app.yaml cron.yaml
+```
+
+Then access your site, and continue the installation step. The URL is:
+https://PROJECT_ID.appspot.com/
+
+Go to the Dashboard at https://PROJECT_ID.appspot.com/wp-admin. On the Plugins page, activate the following
+plugins:
+
+  - GCS media plugin
+
+After activating the plugins, try uploading a media object in a new post
+and confirm the image is uploaded to the GCS bucket by visiting the
+[Google Cloud console's Storage page][cloud-storage-console].
+
+## Various workflows
+
+### Install/Update Wordpress, plugins, and themes
+
+Because the wp-content directory on the server is read-only, you have
+to do this locally. Run WordPress locally and update plugins/themes in
+the local Dashboard, then deploy, then activate them in the production
+Dashboard. You can also use the `wp-cli` utility as follows (be sure to keep
+the cloud SQL proxy running):
+
+```
+# To update Wordpress itself
+$ vendor/bin/wp core update --path=wordpress
+# To update all the plugins
+$ vendor/bin/wp plugin update --all --path=wordpress
+# To update all the themes
+$ vendor/bin/wp theme update --all --path=wordpress
+```
+
+### Remove plugins/themes
+
+First Deactivate them in the production Dashboard, then remove them
+completely locally. The next deployment will remove those files from
+the production environment.
+
+### Update the base image
+
+We sometimes release a security update for
+[the php-docker image][php-docker]. You have to re-deploy your
+WordPress instance to get the security update.
+
+Enjoy your WordPress installation!

+# Google Auth on App Engine Standard for PHP 7.2
+
+This sample application demonstrates how to [Authenticate Users](https://cloud.google.com/appengine/docs/standard/php7/authenticating-users)
+on App Engine Standard.
+
+## Description
+
+This application shows how to authenticate to Google Cloud APIs using two
+different methods. This sample uses Storage as an example, but these methods
+will work for any Google Cloud API.
+
+## Deploy to App Engine
+
+1.  **Enable APIs** - [Enable the Storage API](https://console.cloud.google.com/flows/enableapi?apiid=storage-api.googleapis.com)
+    and create a new project or select an existing project.
+1.  **Clone the repo** and cd into this directory
+    ```
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/appengine/standard/auth
+    ```
+1.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install --no-dev` (if composer is installed locally)
+    or `composer install --no-dev` (if composer is installed globally).
+1.  Run `gcloud app deploy` to deploy to App Engine.
+
+## Run Locally
+
+1.  **Download The Credentials** - Click "Go to credentials" after enabling the
+    APIs. Click "New Credentials" and select "Service Account Key". Create a new
+    service account, use the JSON key type, and select "Create". Once
+    downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS` to
+    the path of the JSON key that was downloaded.
+1.  Run PHP's built-in web server with the command `php -S localhost:8000` and
+    then view the application in your browser at
+    [http://localhost:8000](http://localhost:8000).

-Before you can run or deploy the sample, you will need to do the following:
-
-1. Create a [First Generation Cloud SQL](https://cloud.google.com/sql/docs/create-instance) instance. You can do this from the [Cloud Console](https://console.developers.google.com) or via the [Cloud SDK](https://cloud.google.com/sdk). To create it via the SDK use the following command:
-
-        $ gcloud sql instances create YOUR_INSTANCE_NAME
-
-1. Set the root password on your Cloud SQL instance:
-
-        $ gcloud sql instances set-root-password YOUR_INSTANCE_NAME --password YOUR_INSTANCE_ROOT_PASSWORD
-
-1. Update the connection string in `app.yaml` with your configuration values. These values are used when the application is deployed.
-
-## Run locally
-
-To run locally, you can either run your own MySQL server locally and set the connection string in `app.yaml`, or you can [connect to your CloudSQL instance externally](https://cloud.google.com/sql/docs/external#appaccess).
-
-```sh
-cd php-docs-samples/appengine/standard/cloudsql
-
-# set local mysql connection parameters
-export MYSQL_DSN="mysql:host=127.0.0.1;port=3306;dbname=guestbook"
-export MYSQL_USERNAME=root
-export MYSQL_PASSWORD=
-
-php -S localhost:8080
-```
-
-> be sure the `MYSQL_` environment variables are appropriate for your mysql instance
-
-Now you can view the app running at [http://localhost:8080](http://localhost:8080)
-in your browser.
-
-## Deploy to App Engine
-
-**Prerequisites**
-
-- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
-
-**Deploy with gcloud**
-
-```
-gcloud config set project YOUR_PROJECT_ID
-gcloud app deploy
-gcloud app browse
-```
-
-The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
-in your browser.
-
-## Create the MySQL Tables
-
-Once your application is running, browse to `/create_table` to create the required tables for this example.
+This sample has been moved to [cloud_sql](../../../cloud_sql).

+# Stackdriver Error Reporting on App Engine Standard for PHP 7.2
+
+This application demonstrates how to report errors on App Engine Standard for
+PHP 7.2. It also demonstrates how different PHP error types are handled.
+
+To set up **error reporting** in your App Engine PHP 7.2 application, simply follow
+these two steps:
+
+1. Install the Google Cloud Error Reporting client library
+   ```sh
+   composer require google/cloud-error-reporting
+   ```
+1. Add the command to autoload the "prepend.php" file at the beginning of every
+   request in `composer.json:
+    ```js
+    {
+        "autoload": {
+            "files": ["vendor/google/cloud-error-reporting/src/prepend.php"]
+        }
+    }
+
+    ```
+
+The [`prepend.php`][prepend] file will be executed prior to each request, which
+registers the client library's error handler.
+
+[prepend]: https://github.com/GoogleCloudPlatform/google-cloud-php-errorreporting/blob/main/src/prepend.php
+
+Alternatively, the `prepend.php` file can be manually included to register the
+error handler:
+
+```php
+# This works for files in the root of your project. Adjust __DIR__ accordingly.
+require_once __DIR__ . '/vendor/google/cloud-error-reporting/src/prepend.php';
+```
+
+## Setup the sample
+
+- Install [`composer`](https://getcomposer.org)
+- Install dependencies by running:
+    ```sh
+    composer install
+    ```
+- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
+
+## Deploy the sample
+
+### Deploy with `gcloud`
+
+Deploy the samples by doing the following:
+
+```
+gcloud config set project YOUR_PROJECT_ID
+gcloud app deploy
+gcloud app browse
+```
+
+The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
+in your browser. Browse to `/` to see a list of examples to execute.
+
+### Run Locally
+
+The `prepend.php` file will be autoloaded on each request via composer. You
+can also uncomment the `require_once` statement at the top of
+[`index.php`](index.php), or load the file using `auto_prepend_file` in your
+local `php.ini`.
+
+Now run the sample locally using PHP's build-in web server:
+
+```
+# export environment variables locally which are set by App Engine when deployed
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credentials.json
+export GOOGLE_CLOUD_PROJECT=YOUR_PROJECT_ID
+export GAE_SERVICE=local
+export GAE_VERSION=testing
+
+# Run PHP's built-in web server
+php -S localhost:8000
+```
+
+Browse to `localhost:8000` to see a list of examples to execute.

+# Custom Extensions for App Engine Standard
+
+This sample shows how to compile custom extensions for PHP that aren't already included in
+the [activated extensions](https://cloud.google.com/appengine/docs/standard/php-gen2/runtime#enabled_extensions) 
+or [dynamically loadable extensions](https://cloud.google.com/appengine/docs/standard/php-gen2/runtime#dynamically_loadable_extensions).
+
+This can be useful for activating extensions such as [sqlsrv](https://pecl.php.net/package/sqlsrv) which are not (yet) supported
+by this runtime.
+
+## Steps to compiling and activating custom extensions
+
+1. Put the custom extension code in a directory in your project, so it gets uploaded with
+the rest of your application. In this example we use the directory named `ext`.
+
+2. Put the commands to compile the extension and move it into the `vendor` directory
+in your `composer.json`. 
+
+```json
+{
+    "scripts": {
+        "post-autoload-dump": [
+            "cd ext && phpize --clean && phpize && ./configure && make",
+            "cp ext/modules/sqlsrv.so vendor/"
+        ]
+    }
+}
+```
+**NOTE**: Moving the extension into the `vendor` directory ensures the file is cached. This
+means if you modify the ext directory, you'll need to run gcloud app deploy with the
+`--no-cache argument` to rebuild it.
+
+3. Activate the extension in your `php.ini`:
+```ini
+# php.ini
+extension=/workspace/vendor/my_custom_extension.so
+```
+
+4. Deploy your application as usual with `gcloud app deploy`. In this example, we use `index.php`
+to print `phpinfo()` so we can see that the extension has been activated.

+# Front Controllers on App Engine Standard for PHP 7.2
+
+This app demonstrates how to implement a simple front controller for legacy
+projects. The main code sample is in [`index.php`](index.php#L13). This is one
+example of a front controller. See here for more examples:
+
+ * [front controller implementation using the Slim Framework](../slim-framework/index.php#L26)
+ * [front controller implementation for WordPress](../wordpress/files/gae-app.php#L3)
+ * [front controller implementation using regular expressions](../grpc/index.php#L11)
+
+## Setup
+
+- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
+
+## Deploy
+
+### Run Locally
+
+You can run the sample locally using PHP's build-in web server:
+
+```
+# Run PHP's built-in web server
+php -S localhost:8000
+```
+
+Browse to `localhost:8000` to see a list of examples to execute.
+
+### Deploy with gcloud
+
+Deploy the samples by doing the following:
+
+```
+gcloud config set project YOUR_PROJECT_ID
+gcloud app deploy
+gcloud app browse
+```
+
+The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
+in your browser. Browse to `/` to see a list of examples to execute.

-# HTTP Requests & Google App Engine
-
-This sample application demonstrates how to make [HTTP Requests with Google App Engine](https://cloud.google.com/appengine/docs/php/outbound-requests).
-
-## Setup
-
-- Install [`composer`](https://getcomposer.org)
-- Install dependencies by running:
-
-```sh
-composer install
-```
-
-- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
-
-## Deploy to App Engine
-
-**Run Locally**
-
-Run the sample with [`dev_appserver.py`](https://cloud.google.com/appengine/docs/php/tools/using-local-server):
-
-```
-cd /path/to/php-docs-samples/appengine/standard/http
-dev_appserver.py .
-```
-
-Now browse to `http://localhost:8080` to view the sample.
-
-**Deploy with gcloud**
-
-```
-gcloud config set project YOUR_PROJECT_ID
-gcloud app deploy
-gcloud app browse
-```
-
-The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
-in your browser.
-
-## Using the App
-
-This app shows you how to make http requests in Google App Engine. To use cURL,
-modify the `php.ini` file in the root of this project and uncomment one of the
-valid cURL extensions. [Read our documentation] to understand the difference
-between using cURL and cURLite.

-# Logging for App Engine (standard)
+# Stackdriver Logging on App Engine Standard for PHP 7.2
+
+This application demonstrates how to set up logging on App Engine Standard for
+PHP 7.2. It also demonstrates how different log levels are handled.
+
+To set up **logging** in your App Engine PHP 7.2 application, simply follow
+these two steps:
+
+1. Install the Google Cloud Logging client library
+   ```sh
+   composer require google/cloud-logging
+   ```
+1. Create a [PSR-3][psr3]-compatible logger object
+    ```php
+    use Google\Cloud\Logging\LoggingClient;
+    // Create a PSR-3-Compatible logger
+    $logger = LoggingClient::psrBatchLogger('app');
+    ```
+
+Now you can happily log anything you'd like, and they will show up on
+[console.cloud.google.com/logs](https://console.cloud.google.com/logs):
+
+```php
+// Log messages with varying log levels.
+$logger->info('This will show up as log level INFO');
+$logger->warning('This will show up as log level WARNING');
+$logger->error('This will show up as log level ERROR');
+```
+
+[psr3]: https://www.php-fig.org/psr/psr-3/
+
+## Setup the sample
+
+- Install [`composer`](https://getcomposer.org)
+- Install dependencies by running:
+    ```sh
+    composer install
+    ```
+- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
+
+## Deploy the sample
+
+### Deploy with `gcloud`
+
+Deploy the samples by doing the following:
+
+```
+gcloud config set project YOUR_PROJECT_ID
+gcloud app deploy
+gcloud app browse
+```
+
+The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
+in your browser. Browse to `/` to send in some logs.
+
+### Run Locally
+
+Run the sample locally using PHP's build-in web server:
+
+```
+# export environment variables locally which are set by App Engine when deployed
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credentials.json
+export GOOGLE_CLOUD_PROJECT=YOUR_PROJECT_ID
+
+# Run PHP's built-in web server
+php -S localhost:8000
+```
+
+Browse to `localhost:8000` to send in the logs.
+
+> Note: These logs will show up under the `Global` resource since you are not
+actually sending these from App Engine.

-# Mailgun & Google App Engine
-
-This sample application demonstrates how to use [Mailgun with Google App Engine](https://cloud.google.com/appengine/docs/php/mail/).
-
-## Setup
-
-Before running this sample:
-
-1. You will need a [Mailgun account](http://www.mailgun.com/google).
-2. Update `MAILGUN_DOMAIN` and `MAILGUN_APIKEY` in `index.php` to match your
-   Mailgun credentials. You can use your account's sandbox domain.
-
-## Prerequisites
-
-- Install [`composer`](https://getcomposer.org)
-- Install dependencies by running:
-
-```sh
-composer install
-```
-
-## Deploy to App Engine
-
-**Prerequisites**
-
-- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
-
-**Run Locally**
-
-Run the sample with [`dev_appserver.py`](https://cloud.google.com/appengine/docs/php/tools/using-local-server):
-
-```
-cd /path/to/php-docs-samples/appengine/standard/mailgun
-dev_appserver.py .
-```
-
-Now browse to `http://localhost:8080` to view the sample.
-
-**Deploy with gcloud**
-
-```
-gcloud config set project YOUR_PROJECT_ID
-gcloud app deploy
-gcloud app browse
-```
-
-The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
-in your browser.

-# Mailjet & Google App Engine
-
-This sample application demonstrates how to use [Mailjet with Google App Engine](https://cloud.google.com/appengine/docs/php/mail/).
-
-## Setup
-
-Before running this sample:
-
-1. You will need a [Mailjet account](http://www.mailjet.com).
-2. Update `MAILJET_APIKEY` and `MAILJET_SECRET` in `index.php` to match your
-   Mailjet credentials.
-
-## Prerequisites
-
-- Install [`composer`](https://getcomposer.org)
-- Install dependencies by running:
-
-```sh
-composer install
-```
-
-## Run locally
-
-you can run locally using PHP's built-in web server:
-
-```sh
-cd php-docs-samples/appengine/standard/mailjet
-php -S localhost:8080
-```
-
-Now you can view the app running at [http://localhost:8080](http://localhost:8080)
-in your browser.
-
-## Deploy to App Engine
-
-**Prerequisites**
-
-- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
-
-**Deploy with gcloud**
-
-```
-gcloud config set project YOUR_PROJECT_ID
-gcloud app deploy
-gcloud app browse
-```
-
-The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
-in your browser.

+# Connect to Cloud Memorystore from Google App Engine
+
+This sample application demonstrates how to use
+[Cloud Memorystore for Redis](https://cloud.google.com/memorystore/docs/)
+with Google App Engine for PHP 7.2.
+
+**Prerequisites**
+
+- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
+
+## Setup
+
+Before you can run or deploy the sample, you will need to do the following:
+
+1. Create a [Memorystore instance][memorystore_create]. You can do this from the
+   [Cloud Console](https://console.developers.google.com) or via the
+   [Cloud SDK](https://cloud.google.com/sdk). To create it via the SDK use the
+   following command:
+
+        $ gcloud beta redis instances create YOUR_INSTANCE_NAME --region=REGION_ID
+
+1. Update the environment variables `REDIS_HOST` and `REDIS_PORT` in `app.yaml`
+   with your configuration values. These values are used when the application is
+   deployed. Run the following command to get the values for your instance:
+
+        $ gcloud beta redis instances describe YOUR_INSTANCE_NAME --region=REGION_ID
+
+[memorystore_create]: https://cloud.google.com/memorystore/docs/redis/creating-managing-instances
+
+## Run locally
+
+You can connect to a local database instance by setting the `REDIS_` environment
+variables to your local instance. Alternatively, you can set them to your Cloud
+Memorystore instance, but you will need to create a firewall rule for this,
+which may be a safety concern.
+
+```sh
+cd php-docs-samples/appengine/standard/memorystore
+
+# set local connection parameters
+export REDIS_HOST=127.0.0.1
+export REDIS_PORT=6379
+
+php -S localhost:8080
+```
+
+> be sure the `REDIS_` environment variables are appropriate for your Redis
+  instance.
+
+Now you can view the app running at [http://localhost:8080](http://localhost:8080)
+in your browser.
+
+## Set up Serverless VPC Access
+
+**IMPORTANT** App Engine requires a [Serverless VPC Access][vpc-access]
+connector to connect to Memorystore.
+
+In order for App Engine to connect to Memorystore, you must first
+[configure a Serverless VPC Access connector][configure-vpc]. For example:
+
+```
+# Example command to create a VPC connector. See the docs for more details.
+$ gcloud beta compute networks vpc-access connectors create CONNECTOR_NAME \
+	--region=REGION_ID \
+	--range="10.8.0.0/28"
+	--project=PROJECT_ID
+```
+
+Next, you need to [configure App Engine to connect to your VPC network][connecting-appengine].
+This is done by modifying [`app.yaml`](app.yaml) and setting the full name of
+the connector you just created under `vpc_access_connector`.
+
+```
+vpc_access_connector:
+  name: "projects/PROJECT_ID/locations/REGION_ID/connectors/CONNECTOR_NAME"
+```
+
+**Note**: Serverless VPC Access incurs additional billing. See
+[pricing][vpc-pricing] for details.
+
+[vpc-access]: https://cloud.google.com/vpc
+[configure-vpc]: https://cloud.google.com/vpc/docs/configure-serverless-vpc-access
+[connecting-appengine]: https://cloud.google.com/appengine/docs/standard/python/connecting-vpc#configuring
+[vpc-pricing]: https://cloud.google.com/compute/pricing#network
+
+## Deploy to App Engine
+
+**IMPORTANT** Because Serverless VPC Connector is in *beta*, you must deploy to App Engine
+using the `gcloud beta app deploy` command. Without this, the connection to
+Memorystore *will not work*.
+
+```
+$ gcloud beta app deploy --project PROJECT_ID
+```
+
+Now open `https://{YOUR_PROJECT_ID}.appspot.com/` in your browser to see the running
+app.
+
+**Note**: This example requires the `redis.so` extension to be enabled on your App Engine
+instance. This is done by including [`php.ini`](php.ini) in your project root.
+
+## Troubleshooting
+
+### Connection timed out
+
+If you receive the error "Error: Connection timed out", it's possible your VPC Connector
+is not fully set up. Run the following and check the property `state` is set to READY:
+
+```
+$ gcloud beta compute networks vpc-access connectors describe CONNECTOR_NAME --region=REGION_ID
+```
+
+If you continue to see the timeout error, try creating a new VPC connector with a different
+CIDR `range`.
+
+### Name or service not known
+
+If you receive the following error, make sure you set the `REDIS_HOST` environment variable in `app.yaml` to be the
+host of your Memorystore for Redis instance.
+
+```
+PHP message: PHP Warning: Redis::connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /srv/index.php
+```
+
+### Request contains an invalid argument
+
+If you receive this error, it is because either the `gcloud` command to create the VPC 
+Access connector was missing the `--range` option, or the value supplied to the
+`--range` option did not use the `/28` CIDR mask as required. Be sure to supply a valid
+CIDR range ending in `/28`.

+# Slim Framework on App Engine for PHP
+
+This sample demonstrates how to deploy a *very* basic [Slim][slim] application to
+[Google App Engine for PHP][appengine-php]. For a more complete guide, follow
+the [Building an App][building-an-app] tutorial.
+
+## Setup
+
+Before running this sample:
+
+### Create a project (if you haven't already)
+
+- Go to [Google Developers Console][console] and create a new project.
+
+## Deploy to App Engine
+
+**Deploy with gcloud**
+
+```
+gcloud config set project YOUR_PROJECT_ID
+gcloud app deploy
+gcloud app browse
+```
+
+The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
+in your browser.
+
+## Application Components
+
+The application consists of three components:
+
+ 1. An [`app.yaml`](app.yaml) which sets your application runtime to be `php81`.
+ 2. A [`composer.json`](composer.json) which declares your application's dependencies.
+ 3. An [`index.php`](index.php) which handles all the requests which get routed to your app.
+
+The `index.php` file is the most important. All applications running on App Engine
+for PHP require use of a [front controller][front-controller] file.

-# Cloud Storage & Google App Engine
-
-This sample application demonstrates how to use [Cloud Storage with Google App Engine](https://cloud.google.com/appengine/docs/php/googlestorage/).
-
-## Setup
-
-Before running this sample:
-
-## Prerequisites
-
-- Install [`composer`](https://getcomposer.org)
-- Install dependencies by running:
-
-```sh
-composer install
-```
-
-## Setup
-
-Before you can run or deploy the sample, you will need to do the following:
-
-1. Set `<your-bucket-name>` in `index.php` to the name of your Cloud Storage Bucket.
-
-## Deploy to App Engine
-
-**Prerequisites**
-
-- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
-
-**Run Locally**
-
-Create a local directory for the Dev AppServer to use for Cloud Storage:
-
-```
-mkdir /tmp/gs
-```
-
-> Note: This directory can be wherever you like, as long as it's consistent with
-  the `--storage_path` option below.
-
-Run the sample with `dev_appserver.py`:
-
-```
-cd /path/to/php-docs-samples/appengine/standard/storage
-dev_appserver.py --php_executable=/usr/local/bin/php-cgi --storage_path=/tmp/gs .
-```
-
-> Note: Your PHP executable path may be different than the one above.
-
-Now browse to `http://localhost:8080` to view the sample.
-
-**Deploy with gcloud**
-
-```
-gcloud config set project YOUR_PROJECT_ID
-gcloud app deploy
-gcloud app browse
-```
-
-The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
-in your browser.

+# Google Cloud Tasks Handler on App Engine Standard for PHP 7.2
+
+The Task Handler sample application demonstrates how to handle a task from a Cloud Tasks Appengine Queue.
+
+## Setup the sample
+
+- Install [`composer`](https://getcomposer.org)
+- Install dependencies by running:
+    ```sh
+    composer install
+    ```
+- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
+
+## Deploy the sample
+
+### Deploy with `gcloud`
+
+Deploy the samples by doing the following:
+
+```
+gcloud config set project YOUR_PROJECT_ID
+gcloud app deploy
+gcloud app browse
+```
+
+The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
+in your browser. Browse to `/` to send in some logs.
+
+### Run Locally
+
+Run the sample locally using PHP's build-in web server:
+
+```
+# export environment variables locally which are set by App Engine when deployed
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credentials.json
+export GOOGLE_CLOUD_PROJECT=YOUR_PROJECT_ID
+
+# Run PHP's built-in web server
+php -S localhost:8000
+```
+
+Browse to `localhost:8000` to send in the logs.
+
+> Note: These logs will show up under the `Global` resource since you are not
+actually sending these from App Engine.

+# Google Cloud Tasks App Engine Queue Samples
+
+## Description
+
+All code in the snippets directory demonstrate how to invoke Cloud Tasks from PHP.
+
+`src/create_task.php` is a simple function to create tasks with App Engine routing.
+
+## Setup:
+
+1.  **Enable APIs** - [Enable the Cloud Tasks API](https://console.cloud.google.com/flows/enableapi?apiid=cloudtasks)
+    and create a new project or select an existing project.
+2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click "New Credentials"
+    and select "Service Account Key". Create a new service account, use the JSON key type, and
+    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
+    to the path of the JSON key that was downloaded.
+3.  **Clone the repo** and cd into this directory
+
+    ```sh
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/appengine/standard/tasks
+    ```
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+5.  Create a Queue
+    To create a queue using the Cloud SDK, use the following gcloud command:
+    ```sh
+    gcloud tasks queues create my-appengine-queue
+    ```
+6. Set environment variables:
+
+    First, your project ID:
+
+        export PROJECT_ID=my-project-id
+
+    Then the queue ID, as specified at queue creation time. Queue IDs already
+    created can be listed with `gcloud tasks queues list`.
+
+        export QUEUE_ID=my-appengine-queue
+
+    Then, identify the queue location
+
+        Determine the location ID, which can be discovered with
+        `gcloud tasks queues describe $QUEUE_ID`, with the location embedded in
+        the "name" value (for instance, if the name is
+        "projects/my-project/locations/us-central1/queues/my-pull-queue", then the
+        location is "us-central1").
+
+        export LOCATION_ID=us-central1
+
+## Using App Engine Routing
+1. Run `php src/create_task.php`. The usage will print for each if no arguments are provided:
+
+    ```
+    $> php src/create_task.php
+    Usage: php src/create_task.php PROJECT_ID LOCATION_ID QUEUE_ID [PAYLOAD]
+    ```

+# Stackdriver Trace on App Engine Standard for PHP 7.2
+
+This app demonstrates how to set up Stackdriver Trace on App Engine Standard
+for PHP 7.2.
+
+## Setup
+
+- Install [`composer`](https://getcomposer.org)
+- Install dependencies by running:
+
+    ```sh
+    composer install
+    ```
+
+- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
+
+## Deploy
+
+### Run Locally
+
+You can run these samples locally using PHP's build-in web server:
+
+```
+# export environment variables locally which are set by app engine when deployed
+export GOOGLE_CLOUD_PROJECT=YOUR_PROJECT_ID
+
+# Run PHP's built-in web server
+php -S localhost:8000
+```
+
+You will then be able to see your application traces in the
+[Trace UI](https://console.cloud.google.com/traces/overview).
+
+### Deploy with gcloud
+
+Deploy the samples by doing the following:
+
+```
+gcloud config set project YOUR_PROJECT_ID
+gcloud app deploy
+gcloud app browse
+```
+
+The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
+in your browser. Browse to `/` to execute a trace. You will then be able to see
+your traces in the [Trace UI](https://console.cloud.google.com/traces/overview).

-# Twilio & Google App Engine (Standard)
-
-This sample application demonstrates how to use [Twilio with Google App Engine](https://cloud.google.com/appengine/docs/php/sms/twilio).
-
-## Setup
-
-Before running this sample:
-
-1. You will need a [Twilio account](https://www.twilio.com/user/account).
-1. Update `TWILIO_ACCOUNT_SID` and `TWILIO_AUTH_TOKEN` in `index.php` to match your
-   Twilio credentials. These can be found in your [account settings]
-   (https://www.twilio.com/user/account/settings)
-1. Update `TWILIO_FROM_NUMBER` in `index.php` with a number you have authorized
-   for sending messages. Follow [Twilio's documentation]
-   (https://www.twilio.com/user/account/phone-numbers/getting-started) to set
-   this up.
-
-## Prerequisites
-
-- Install [`composer`](https://getcomposer.org)
-- Install dependencies by running:
-
-```sh
-composer install
-```
-
-## Run locally
-
-you can run locally using PHP's built-in web server:
-
-```sh
-cd php-docs-samples/appengine/standard/twilio
-php -S localhost:8080
-```
-
-Now you can view the app running at [http://localhost:8080](http://localhost:8080)
-in your browser.
-
-## Deploy to App Engine
-
-**Prerequisites**
-
-- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
-
-**Deploy with gcloud**
-
-```
-gcloud config set project YOUR_PROJECT_ID
-gcloud app deploy
-gcloud app browse
-```
-
-The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
-in your browser.

-# A helper command for running WordPress on Google Cloud Platform
+# WordPress for Google App Engine
 
-This is a small command line tool for downloading and configuring
-WordPress for Google Cloud Platform. The script allows you to create a
-working WordPress project for the
-[App Engine standard environment][appengine-standard] or the
-[App Engine flexible environment][appengine-flexible].
+This is a list of samples which contain a CLI tool for deploying WordPress to App Engine.
 
-## Common Prerequisites
+## Index
 
-* Install [Composer][composer]
-* Create a new Cloud Project using the [Cloud Console][cloud-console]
-* Enable Billing on that project
-* [Enable Cloud SQL API][cloud-sql-api-enable]
-* Install [Google Cloud SDK][gcloud-sdk]
-* Install the [mysql-client][mysql-client] command line tool
-* [Install Memcache][memcache-installation]
-
-## Project preparation
-
-Configure Google Cloud SDK with your account and the appropriate project ID:
-
-```
-$ gcloud init
-```
-
-Create an App Engine application within your new project:
-
-```
-$ gcloud app create
-```
-
-Then configure the App Engine default GCS bucket for later use. The default App
-Engine bucket is named YOUR_PROJECT_ID.appspot.com. Change the default Access
-Control List (ACL) of that bucket as follows:
-
-```
-$ gsutil defacl ch -u AllUsers:R gs://YOUR_PROJECT_ID.appspot.com
-```
-
-### Create and configure a Cloud SQL for MySQL 2nd generation instance
-
-Note: In this guide, we use `wp` for various resource names; the instance
-name, the database name, and the user name.
-    
-Create a new Cloud SQL for MySQL Second Generation instance with the following
-command:
-
-```
-$ gcloud sql instances create wp \
-  --activation-policy=ALWAYS \
-    --tier=db-n1-standard-1
-```
-
-Note: you can choose `db-f1-micro` or `db-g1-small` instead of
-`db-n1-standard-1` for the Cloud SQL machine type, especially for the
-development or testing purpose. However, those machine types are not
-recommended for production use and are not eligible for Cloud SQL SLA
-coverage. See our [Cloud SQL SLA](https://cloud.google.com/sql/sla)
-for more details.
-
-Then change the root password for your instance:
-
-```
-$ gcloud sql users set-password root % \
-  --instance wp --password=YOUR_INSTANCE_ROOT_PASSWORD # Don't use this password!
-```
-
-To access this MySQL instance, use Cloud SQL Proxy. [Download][cloud-sql-proxy-download]
-it to your local computer and make it executable.
-
-Go to the [the Credentials section][credentials-section] of your project in the
-Console. Click 'Create credentials' and then click 'Service account key.' For
-the Service account, select 'App Engine app default service account.' Then
-click 'Create' to create and download the JSON service account key to your
-local machine. Save it to a safe place.
-
-Run the proxy by the following command:
-
-```
-$ cloud_sql_proxy \
-  -dir /tmp/cloudsql \
-    -instances=YOUR_PROJECT_ID:us-central1:wp=tcp:3306 \
-      -credential_file=PATH_TO_YOUR_SERVICE_ACCOUNT_JSON_FILE
-```
-
-Now you can access the Cloud SQL instance with the MySQL client in a separate
-command line tab. Create a new database and a user as follows:
-
-```
-$ mysql -h 127.0.0.1 -u root -p
-mysql> create database wp;
-mysql> create user 'wp'@'%' identified by 'PASSWORD'; // Don't use this password!
-mysql> grant all on wp.* to 'wp'@'%';
-mysql> exit
-```
-
-## How to use
-
-First install the dependencies in this directory as follows:
-
-```
-$ composer install
-```
-
-If it complains about extensions, please install `phar` and `zip` PHP
-extensions and retry.
-
-Then run the helper command.
-
-```
-$ php wordpress-helper.php setup
-```
-
-The command asks you several questions, please answer them. Then you'll have a
-new WordPress project. By default it will create `my-wordpress-project` in the
-current directory.
-
-## Deployment
-
-CD into your WordPress project directory and run the following command to
-deploy:
-
-```
-$ cd my-wordpress-project
-$ gcloud app deploy \
-    --promote --stop-previous-version app.yaml cron.yaml
-```
-
-Then access your site, and continue the installation step. The URL is:
-https://PROJECT_ID.appspot.com/
-
-Go to the Dashboard at https://PROJECT_ID.appspot.com/wp-admin. On the Plugins page, activate the following
-plugins:
-
-
-- For the standard environment
-  - Batcache Manager
-  - Google App Engine for WordPress (also set the e-mail address in its
-    settings page)
-- For the flexible environment
-  - Batcache Manager
-  - GCS media plugin
-
-After activating the plugins, try uploading a media object in a new post 
-and confirm the image is uploaded to the GCS bucket by visiting the 
-[Google Cloud console's Storage page][cloud-storage-console].
-
-## Check if the Batcache plugin is working
-
-On the plugin page in the WordPress dashboard, click on the Drop-ins tab near
-the top. You should see 2 drop-ins are activated: `advanced-cache.php` and
-`object-cache.php`.
-
-To make sure it’s really working, you can open an incognito window and
-visit the site because the cache plugin only serves from cache to
-anonymous users. Then go to
-[the memcache dashboard in the Cloud Console][memcache-dashboard] and
-check the hit ratio and number of items in cache.
-
-## Various workflows
-
-### Install/Update Wordpress, plugins, and themes
-
-Because the wp-content directory on the server is read-only, you have
-to do this locally. Run WordPress locally and update plugins/themes in
-the local Dashboard, then deploy, then activate them in the production
-Dashboard. You can also use the `wp-cli` utility as follows (be sure to keep
-the cloud SQL proxy running):
-
-```
-# To update Wordpress itself
-$ vendor/bin/wp core update --path=wordpress
-# To update all the plugins
-$ vendor/bin/wp plugin update --all --path=wordpress
-# To update all the themes
-$ vendor/bin/wp theme update --all --path=wordpress
-```
-
-If you're using App Engine Standard, You may get the following error:
-
-```
-Failed opening required 'google/appengine/api/urlfetch_service_pb.php'
-```
-
-You can set a `WP_CLI_PHP_ARGS` environment variable to add
-`include_path` PHP configuration for wp-cli.
-
-```
-$ export WP_CLI_PHP_ARGS='-d include_path=vendor/google/appengine-php-sdk'
-```
-
-Then try the above commands again.
-
-### Remove plugins/themes
-
-First Deactivate them in the production Dashboard, then remove them
-completely locally. The next deployment will remove those files from
-the production environment.
-
-### Update the base image
-
-We sometimes release a security update for
-[the php-docker image][php-docker]. You have to re-deploy your
-WordPress instance to get the security update.
-
-Enjoy your WordPress installation!

-deploying to either App Engine Flexible (which allows usage of Compute Engine
-credentials since App Engine Flexible apps run on Compute Engine instances) or
-App Engine Standard. Run either `gcloud app deploy app-standard.yaml` or
-`gcloud app deploy app-flex.yaml`.

+# Google Bigtable Sample
+
+## Description
+
+These samples show how to use the
+[Cloud Bigtable API][bigtable] from PHP.
+
+All code in the `src` directory demonstrates how to connect to Cloud Bigtable and run some basic operations to create instance, create cluster, delete instance and delete cluster.
+
+[bigtable]: https://cloud.google.com/bigtable/docs/reference/libraries
+
+## Build and Run
+1.  **Enable APIs** - [Enable the Bigtable API](https://console.cloud.google.com/flows/enableapi?apiid=bigtable)
+    and create a new project or select an existing project.
+2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click "New Credentials"
+    and select "Service Account Key". Create a new service account, use the JSON key type, and
+    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
+    to the path of the JSON key that was downloaded.
+3.  **Clone the repo** and cd into this directory
+    ```sh
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/bigtable/api
+    ```
+
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+5.  Run `php SNIPPET_NAME.php`. The usage will print for each if no arguments
+    are provided:
+    ```sh
+    $ php src/run_instance_operations.php
+    Usage: php src/run_instance_operations.php PROJECT_ID INSTANCE_ID TABLE_ID
+
+    $ php src/run_instance_operations.php your-project-id your-instance-id your-table-id
+    ```

+# Google Cloud CDN Sign URL
+
+PHP implementation of [`gcloud compute sign-url`](https://cloud.google.com/sdk/gcloud/reference/compute/sign-url) based on [Google Cloud CDN Documentation](https://cloud.google.com/cdn/docs/using-signed-urls#signing_urls).
+The provided file includes implementation of base64url encode and decode functions based on [RFC4648 Section 5](https://tools.ietf.org/html/rfc4648#section-5).
+
+## Usage
+
+```php
+require_once 'signUrl.php';
+$base64url_key = 'wpLL7f4VB9RNe_WI0BBGmA=='; // head -c 16 /dev/urandom | base64 | tr +/ -_
+$signed_url = signUrl('https://example.com/foo', 'my-key', $base64url_key, time() + 1800);
+echo $signed_url;
+```

+# Connection to Cloud SQL - MySQL
+
+## Before you begin
+
+1. Before you use this code sample, you need to have
+[Composer](https://getcomposer.org/) installed or downloaded into this folder.
+Download instructions can be found [here](https://getcomposer.org/download/).
+Once you've installed composer, use it to install required dependencies by
+running `composer install`.
+2. Create a MySQL Cloud SQL Instance by following these
+[instructions](https://cloud.google.com/sql/docs/mysql/create-instance). Note
+the connection string, database user, and database password that you create.
+3. Create a database for your application by following these
+[instructions](https://cloud.google.com/sql/docs/mysql/create-manage-databases).
+Note the database name.
+4. Create a service account with the 'Cloud SQL Client' permissions by following
+these
+[instructions](https://cloud.google.com/sql/docs/mysql/connect-external-app#4_if_required_by_your_authentication_method_create_a_service_account).
+Download a JSON key to use to authenticate your connection.
+
+## Running Locally
+
+To run this application locally, download and install the `cloud_sql_proxy` by
+following the instructions [here](https://cloud.google.com/sql/docs/mysql/sql-proxy#install).
+
+Instructions are provided below for using the proxy with a TCP connection or a
+Unix domain socket. On Linux or macOS, you can use either option, but the
+Windows proxy currently requires a TCP connection.
+
+### Launch proxy with Unix Domain Socket
+NOTE: this option is currently only supported on Linux and macOS. Windows users
+should use the TCP option.
+
+To use a Unix socket, you'll need to create a directory and give write access to
+the user running the proxy:
+
+```bash
+sudo mkdir /cloudsql
+sudo chown -R $USER /cloudsql
+```
+
+Use these terminal commands to initialize other environment variables as well:
+
+```bash
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account/key.json
+export INSTANCE_CONNECTION_NAME='<PROJECT-ID>:<INSTANCE-REGION>:<INSTANCE-NAME>'
+export INSTANCE_UNIX_SOCKET='/cloudsql/<PROJECT-ID>:<INSTANCE-REGION>:<INSTANCE-NAME>'
+export DB_USER='<DB_USER_NAME>'
+export DB_PASS='<DB_PASSWORD>'
+export DB_NAME='<DB_NAME>'
+```
+
+Note: Saving credentials in environment variables is convenient, but not
+secure - consider a more secure solution such as
+[Secret Manager](https://cloud.google.com/secret-manager/) to help keep secrets
+safe.
+
+Then use the following command to launch the proxy in the background:
+
+```bash
+./cloud_sql_proxy -dir=/cloudsql --instances=$INSTANCE_CONNECTION_NAME --credential_file=$GOOGLE_APPLICATION_CREDENTIALS &
+```
+
+### Launch proxy with TCP
+To run the sample locally with a TCP connection, set environment variables and
+launch the proxy as shown below.
+
+#### Linux / Mac OS
+Use these terminal commands to initialize environment variables:
+
+```bash
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account/key.json
+export INSTANCE_CONNECTION_NAME='<PROJECT-ID>:<INSTANCE-REGION>:<INSTANCE-NAME>'
+export INSTANCE_HOST='127.0.0.1'
+export DB_USER='<DB_USER_NAME>'
+export DB_PASS='<DB_PASSWORD>'
+export DB_NAME='<DB_NAME>'
+```
+
+Note: Saving credentials in environment variables is convenient, but not
+secure - consider a more secure solution such as
+[Secret Manager](https://cloud.google.com/secret-manager/) to help keep secrets
+safe.
+
+Then use the following command to launch the proxy in the background:
+
+```bash
+./cloud_sql_proxy -instances=$INSTANCE_CONNECTION_NAME=tcp:3306 -credential_file=$GOOGLE_APPLICATION_CREDENTIALS &
+```
+
+#### Windows/PowerShell
+Use these PowerShell commands to initialize environment variables:
+
+```powershell
+$env:GOOGLE_APPLICATION_CREDENTIALS="<CREDENTIALS_JSON_FILE>"
+$env:INSTANCE_HOST="127.0.0.1"
+$env:DB_USER="<DB_USER_NAME>"
+$env:DB_PASS="<DB_PASSWORD>"
+$env:DB_NAME="<DB_NAME>"
+```
+
+Note: Saving credentials in environment variables is convenient, but not
+secure - consider a more secure solution such as
+[Secret Manager](https://cloud.google.com/secret-manager/) to help keep secrets
+safe.
+
+Then use the following command to launch the proxy in a separate PowerShell
+session:
+
+```powershell
+Start-Process -filepath "C:\<path to proxy exe>" -ArgumentList "-instances=<project-id>:<region>:<instance-name>=tcp:3306 -credential_file=<CREDENTIALS_JSON_FILE>"
+```
+
+### Testing the application
+Execute the following to start the application server:
+``` bash
+php -S localhost:8080
+```
+
+Navigate towards http://localhost:8080 to verify your application is running
+correctly.
+
+## Google App Engine Standard
+Note: App Engine Standard does not support TCP connections to Cloud SQL
+instances, only Unix socket connections.
+
+To run on GAE-Standard, create an App Engine project by following the setup for
+these
+[instructions](https://cloud.google.com/appengine/docs/standard/php7/quickstart#before-you-begin).
+
+First, update [app.standard.yaml](app.standard.yaml) with the correct values to pass the
+environment variables into the runtime.
+
+Next, delete the `composer.lock` file if it exists. This will ensure that the sample app
+is built with the package versions specified in `composer.json`.
+
+Next, the following command will deploy the application to your Google Cloud
+project:
+
+```bash
+$ gcloud app deploy app.standard.yaml
+```
+
+## Google App Engine Flex
+To run on App Engine Flex, create an App Engine project by following the setup
+for these
+[instructions](https://cloud.google.com/appengine/docs/standard/php7/quickstart#before-you-begin).
+
+First, update [app.flex.yaml](app.flex.yaml) with the correct values to pass the environment
+variables into the runtime.
+
+To use a TCP connection instead of a Unix socket to connect your sample to your
+Cloud SQL instance on App Engine, make sure to uncomment the `INSTANCE_HOST`
+field under `env_variables`. Also make sure to remove the uncommented
+`beta_settings` and `cloud_sql_instances` fields and replace them with the
+commented `beta_settings` and `cloud_sql_instances` fields.
+
+Then, make sure that the App Engine default service account
+`<PROJECT-ID>@appspot.gserviceaccount.com` has
+the IAM role `Cloud SQL Client`.
+
+Also, make sure that the Cloud Build service account
+`cloudbuild@<PROJECT-ID>.iam.gserviceaccount.com` has
+the IAM role `Cloud SQL Client`.
+
+Next, the following command will deploy the application to your Google Cloud
+project:
+
+```bash
+$ gcloud beta app deploy app.flex.yaml
+```

+# Connection to Cloud SQL - PostgreSQL
+
+## Before you begin
+
+1. Before you use this code sample, you need to have
+[Composer](https://getcomposer.org/) installed or downloaded into this folder.
+Download instructions can be found [here](https://getcomposer.org/download/).
+Once you've installed composer, use it to install required dependencies by
+running `composer install`.
+2. Create a PostgreSQL Cloud SQL Instance by following these
+[instructions](https://cloud.google.com/sql/docs/postgres/create-instance). Note
+the connection string, database user, and database password that you create.
+3. Create a database for your application by following these
+[instructions](https://cloud.google.com/sql/docs/postgres/create-manage-databases).
+Note the database name.
+4. Create a service account with the 'Cloud SQL Client' permissions by following
+these
+[instructions](https://cloud.google.com/sql/docs/postgres/connect-external-app#4_if_required_by_your_authentication_method_create_a_service_account).
+Download a JSON key to use to authenticate your connection.
+
+## Running Locally
+
+To run this application locally, download and install the `cloud_sql_proxy` by
+following the instructions
+[here](https://cloud.google.com/sql/docs/postgres/sql-proxy#install).
+
+Instructions are provided below for using the proxy with a TCP connection or a
+Unix domain socket. On Linux or macOS, you can use either option, but the
+Windows proxy requires a TCP connection.
+
+### Launch proxy with Unix Domain Socket
+
+NOTE: this option is currently only supported on Linux and macOS. Windows users
+should use the TCP option.
+
+To use a Unix socket, you'll need to create a directory and give access to the
+user running the proxy:
+
+```bash
+sudo mkdir /cloudsql
+sudo chown -R $USER /cloudsql
+```
+
+Use these terminal commands to initialize environment variables:
+
+```bash
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account/key.json
+export INSTANCE_CONNECTION_NAME='<PROJECT-ID>:<INSTANCE-REGION>:<INSTANCE-NAME>'
+export INSTANCE_UNIX_SOCKET='/cloudsql/<PROJECT-ID>:<INSTANCE-REGION>:<INSTANCE-NAME>'
+export DB_USER='<DB_USER_NAME>'
+export DB_PASS='<DB_PASSWORD>'
+export DB_NAME='<DB_NAME>'
+```
+
+Note: Saving credentials in environment variables is convenient, but not
+secure - consider a more secure solution such as
+[Secret Manager](https://cloud.google.com/secret-manager/) to help keep secrets
+safe.
+
+Then use the following command to launch the proxy in the background:
+
+```bash
+./cloud_sql_proxy -dir=/cloudsql --instances=$INSTANCE_CONNECTION_NAME --credential_file=$GOOGLE_APPLICATION_CREDENTIALS &
+```
+
+### Launch proxy with TCP
+
+To run the sample locally with a TCP connection, set environment variables and
+launch the proxy as shown below.
+
+#### Linux / Mac OS
+
+Use these terminal commands to initialize environment variables:
+
+```bash
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account/key.json
+export INSTANCE_CONNECTION_NAME='<PROJECT-ID>:<INSTANCE-REGION>:<INSTANCE-NAME>'
+export INSTANCE_HOST='127.0.0.1'
+export DB_USER='<DB_USER_NAME>'
+export DB_PASS='<DB_PASSWORD>'
+export DB_NAME='<DB_NAME>'
+```
+
+Note: Saving credentials in environment variables is convenient, but not
+secure - consider a more secure solution such as
+[Secret Manager](https://cloud.google.com/secret-manager/) to help keep secrets
+safe.
+
+Then use the following command to launch the proxy in the background:
+
+```bash
+./cloud_sql_proxy -instances=$INSTANCE_CONNECTION_NAME=tcp:5432 -credential_file=$GOOGLE_APPLICATION_CREDENTIALS &
+```
+
+#### Windows/PowerShell
+
+Use these PowerShell commands to initialize environment variables:
+
+```bash
+$env:GOOGLE_APPLICATION_CREDENTIALS="<CREDENTIALS_JSON_FILE>"
+$env:INSTANCE_HOST="127.0.0.1"
+$env:DB_USER="<DB_USER_NAME>"
+$env:DB_PASS="<DB_PASSWORD>"
+$env:DB_NAME="<DB_NAME>
+```
+
+Note: Saving credentials in environment variables is convenient, but not
+secure - consider a more secure solution such as
+[Secret Manager](https://cloud.google.com/secret-manager/) to help keep secrets
+safe.
+
+Then use the following command to launch the proxy in a separate PowerShell
+session:
+
+```powershell
+Start-Process -filepath "C:\<path to proxy exe>" -ArgumentList "-instances=<project-id>:<region>:<instance-name>=tcp:5432 -credential_file=<CREDENTIALS_JSON_FILE>"
+```
+
+### Testing the application
+
+Execute the following to start the application server:
+
+```bash
+$ php -S localhost:8080
+```
+
+Navigate towards http://localhost:8080 to verify your application is running
+correctly.
+
+## Google App Engine Standard
+Note: App Engine Standard does not support TCP connections to Cloud SQL
+instances, only Unix socket connections.
+
+To run on App Engine Standard, create an App Engine project by following the
+setup for these
+[instructions](https://cloud.google.com/appengine/docs/standard/php7/quickstart#before-you-begin).
+
+First, update [app.standard.yaml](app.standard.yaml) with the correct values to pass the
+environment variables into the runtime.
+
+Next, the following command will deploy the application to your Google Cloud
+project:
+
+```bash
+$ gcloud app deploy app.standard.yaml
+```
+
+## Google App Engine Flex
+To run on App Engine Flex, create an App Engine project by following the setup
+for these
+[instructions](https://cloud.google.com/appengine/docs/standard/php7/quickstart#before-you-begin).
+
+First, update [app.flex.yaml](app.flex.yaml) with the correct values to pass the environment
+variables into the runtime.
+
+To use a TCP connection instead of a Unix socket to connect your sample to your
+Cloud SQL instance on App Engine, make sure to uncomment the `INSTANCE_HOST`
+field under `env_variables`. Also make sure to remove the uncommented
+`beta_settings` and `cloud_sql_instances` fields and replace them with the
+commented `beta_settings` and `cloud_sql_instances` fields.
+
+Then, make sure that the App Engine default service account
+`<PROJECT-ID>@appspot.gserviceaccount.com` has
+the IAM role `Cloud SQL Client`.
+
+Also, make sure that the Cloud Build service account
+`cloudbuild@<PROJECT-ID>.iam.gserviceaccount.com` has
+the IAM role `Cloud SQL Client`.
+
+Next, the following command will deploy the application to your Google Cloud
+project:
+
+```bash
+$ gcloud beta app deploy app.flex.yaml
+```
+

+# Connection to Cloud SQL - SQL Server
+
+## Before you begin
+
+1. This code sample requires the `pdo_sqlsrv` extension to be installed and enabled. For more information, including getting started guides, refer to the [source repository](https://github.com/Microsoft/msphpsql).
+2. Before you use this code sample, you need to have [Composer](https://getcomposer.org/) installed or downloaded into this folder. Download instructions can be found [here](https://getcomposer.org/download/). Once you've installed composer, use it to install required dependencies by running `composer install`.
+3. Create a SQL Server Cloud SQL Instance by following these [instructions](https://cloud.google.com/sql/docs/sqlserver/create-instance). Note the connection string, database user, and database password that you create.
+4. Create a database for your application by following these [instructions](https://cloud.google.com/sql/docs/sqlserver/create-manage-databases). Note the database name.
+5. Create a service account with the 'Cloud SQL Client' permissions by following these [instructions](https://cloud.google.com/sql/docs/postgres/connect-external-app#4_if_required_by_your_authentication_method_create_a_service_account). Download a JSON key to use to authenticate your connection.
+
+## Running Locally
+
+To run this application locally, download and install the `cloud_sql_proxy` by following the instructions [here](https://cloud.google.com/sql/docs/sqlserver/sql-proxy#install).
+
+To authenticate with Cloud SQL, set the `$GOOGLE_APPLICATION_CREDENTIALS` environment variable:
+
+```bash
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account/key.json
+```
+
+To run the Cloud SQL proxy, you need to set the instance connection name. See the instructions [here](https://cloud.google.com/sql/docs/sqlserver/connect-instance-auth-proxy#get-connection-name) for finding the instance connection name.
+
+```bash
+export INSTANCE_CONNECTION_NAME='<PROJECT-ID>:<INSTANCE-REGION>:<INSTANCE-NAME>'
+```
+
+Once the proxy is ready, use one of the following commands to start the proxy in the background.
+
+You may connect to your instance via TCP. To connect via TCP, you must provide a port as part of the instance name, as demonstrated below.
+
+```bash
+$ ./cloud_sql_proxy \
+    --instances=$INSTANCE_CONNECTION_NAME=tcp:1433 \
+    --credential_file=$GOOGLE_APPLICATION_CREDENTIALS
+```
+
+### Set Configuration Values
+
+Set the required environment variables for your connection to Cloud SQL.
+
+```bash
+export DB_USER='<DB_USER_NAME>'
+export DB_PASS='<DB_PASSWORD>'
+export DB_NAME='<DB_NAME>'
+export DB_HOST='127.0.0.1'
+```
+
+Note: Saving credentials in environment variables is convenient, but not secure - consider a more secure solution such as [Secret Manager](https://cloud.google.com/secret-manager/) to help keep secrets safe.
+
+Execute the following:
+
+```bash
+$ php -S localhost:8080
+```
+
+Navigate towards http://localhost:8080 to verify your application is running correctly.
+
+## Google App Engine Flex
+
+To run on App Engine Flex, create an App Engine project by following the setup for these [instructions](https://cloud.google.com/appengine/docs/standard/php7/quickstart#before-you-begin).
+
+First, update [app.yaml](app.yaml) with the correct values to pass the environment variables into the runtime.
+
+In order to use the `sqlsrv` extension, you will need to build a [custom runtime](https://cloud.google.com/appengine/docs/flexible/custom-runtimes/quickstart). The `Dockerfile` in this sample contains a simple example of a custom PHP 7.2 runtime based off of the default App Engine Flex image with the `pdo_sqlsrv` extension installed.
+
+Then, make sure that the App Engine default service account
+`<PROJECT-ID>@appspot.gserviceaccount.com` has
+the IAM role `Cloud SQL Client`.
+
+Also, make sure that the Cloud Build service account
+`cloudbuild@<PROJECT-ID>.iam.gserviceaccount.com` has
+the IAM role `Cloud SQL Client`.
+
+Next, the following command will deploy the application to your Google Cloud project:
+
+```bash
+$ gcloud beta app deploy
+```

+Google Cloud Compute Engine PHP Samples - Firewall
+==================================================

+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=compute/cloud-client/instances
+
+This directory contains samples for calling [Google Cloud Compute Engine][compute] APIs
+from PHP. Specifically, they show how to manage your [VPC firewall rules][firewall_rules].
+
+[compute]: https://cloud.google.com/compute/docs/apis
+[firewall_rules]: https://cloud.google.com/vpc/docs/firewalls
+
+## Setup
+
+### Authentication
+
+Authentication is typically done through [Application Default Credentials][adc]
+which means you do not have to change the code to authenticate as long as
+your environment has credentials. You have a few options for setting up
+authentication:
+
+1. When running locally, use the [Google Cloud SDK][google-cloud-sdk]
+
+        gcloud auth application-default login
+
+1. When running on App Engine or Compute Engine, credentials are already
+   set. However, you may need to configure your Compute Engine instance
+   with [additional scopes][additional_scopes].
+
+1. You can create a [Service Account key file][service_account_key_file]. This file can be used to
+   authenticate to Google Cloud Platform services from any environment. To use
+   the file, set the ``GOOGLE_APPLICATION_CREDENTIALS`` environment variable to
+   the path to the key file, for example:
+
+        export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account.json
+
+[adc]: https://cloud.google.com/docs/authentication#getting_credentials_for_server-centric_flow
+[additional_scopes]: https://cloud.google.com/compute/docs/authentication#using
+[service_account_key_file]: https://developers.google.com/identity/protocols/OAuth2ServiceAccount#creatinganaccount
+
+## Install Dependencies
+
+1. **Install dependencies** using [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+
+1. Create a [service account](https://cloud.google.com/iam/docs/creating-managing-service-accounts#creating).
+
+1. [Download the json key file](https://cloud.google.com/iam/docs/creating-managing-service-account-keys#getting_a_service_account_key)
+   of the service account.
+
+1. Set the `GOOGLE_APPLICATION_CREDENTIALS` environment variable pointing to that file.
+
+## Samples
+
+To run the Compute samples, run any of the files in `src/` on the CLI to print
+the usage instructions:
+
+```
+$ php list_firewall_rules.php
+
+Usage: list_firewall_rules.php $projectId
+
+  @param string $projectId Project ID or project number of the Cloud project you want to list rules from.
+```
+
+### Create a firewall rule
+
+```
+$ php src/create_firewall_rule.php $YOUR_PROJECT_ID "my-firewall-rule"
+Created rule my-firewall-rule
+```
+
+### List firewall rules
+
+```
+$ php src/list_firewall_rules.php $YOUR_PROJECT_ID
+--- Firewall Rules ---
+ -  default-allow-icmp : Allow ICMP from anywhere : https://www.googleapis.com/compute/v1/projects/$YOUR_PROJECT_ID/global/networks/default
+ -  default-allow-internal : Allow internal traffic on the default network : https://www.googleapis.com/compute/v1/projects/$YOUR_PROJECT_ID/global/networks/default
+```
+
+### Print firewall rule
+
+```
+$ php src/print_firewall_rule.php $YOUR_PROJECT_ID "my-firewall-rule"
+ID: $ID
+Kind: compute#firewall
+Name: my-firewall-rule
+Creation Time: $TIMESTAMP
+Direction: INGRESS
+Network: https://www.googleapis.com/compute/v1/projects/$YOUR_PROJECT_ID/global/networks/default
+Disabled: false
+Priority: 100
+Self Link: https://www.googleapis.com/compute/v1/projects/$YOUR_PROJECT_ID/global/firewalls/my-firewall-rule
+Logging Enabled: false
+--Allowed--
+Protocol: tcp
+ - Ports: 80
+ - Ports: 443
+--Source Ranges--
+ - Range: 0.0.0.0/0
+```
+
+### Delete a firewall rule
+
+```
+$ php src/delete_firewall_rule.php $YOUR_PROJECT_ID "my-firewall-rule"
+Rule my-firewall-rule deleted successfully!
+```
+
+### Set firewall rule priority
+
+```
+$ php src/patch_firewall_priority.php $YOUR_PROJECT_ID "my-firewall-rule" 100
+Patched my-firewall-rule priority to 100.
+```
+
+## Troubleshooting
+
+If you get the following error, set the environment variable `GCLOUD_PROJECT` to your project ID:
+
+```
+[Google\Cloud\Core\Exception\GoogleException]
+No project ID was provided, and we were unable to detect a default project ID.
+```
+
+## The client library
+
+This sample uses the [Google Cloud Compute Client Library for PHP][google-cloud-php-compute].
+You can read the documentation for more details on API usage and use GitHub
+to [browse the source][google-cloud-php-source] and [report issues][google-cloud-php-issues].

 # Google Compute Engine PHP Sample Application
 
 ## Description
+
 This is a simple web-based example of calling the Google Compute Engine API
 in PHP.
 
 ## Prerequisites
-Please make sure that all of the following is installed before trying to run
-the sample application.
-
-- [PHP 5.2.x or higher](http://www.php.net/)
-- [PHP Curl extension](http://www.php.net/manual/en/intro.curl.php)
-- [PHP JSON extension](http://php.net/manual/en/book.json.php)
-- The [`google-api-php-client`](https://github.com/google/google-api-php-client)
-  library checked out locally
-
-## Setup Authentication
-NOTE: This README assumes that you have enabled access to the Google Compute
-Engine API via the Google API Console page.
-
-1) Visit https://code.google.com/apis/console/?api=compute to register your
-application.
-- Click on "API Access" in the left column
-- Click the button labeled "Create an OAuth2 client ID..." if you have not
-  generated any client IDs, or "Create another client ID..." if you have
-- Give your application a name and click "Next"
-- Select "Web Application" as the "Application type"
-- Click "Create client ID"
-- Click "Edit settings..." for your new client ID
-- Under the redirect URI, enter the location of your application
-- Click "Update"
-- Click on "Overview" in the left column and note the Project ID
-
-2) Update app.php with the redirect uri, consumer key, secret, and Project ID
-obtained in step 1.
-- Update `YOUR_CLIENT_ID` with your oauth2 client id.
-- Update `YOUR_CLIENT_SECRET` with your oauth2 client secret.
-- Update `YOUR_REDIRECT_URI` with the fully qualified
-  redirect URI.
-- Update `YOUR_GOOGLE_COMPUTE_ENGINE_PROJECT` with your Project ID from the
-  API Console.
+
+ * Run `composer install` in this directory to install the `google/cloud-compute`
+library.
+ * Follow [Getting started with authentication](https://cloud.google.com/docs/authentication/getting-started) to authenticate with Service Account credentials.
 
 ## Running the Sample Application
-3) Load app.php on your web server, and visit the appropriate website in
-your web browser.
+
+Run app.php on your web server:
+
+```
+php -S localhost:8080
+```
+
+Visit the website (http://localhost:8080/app.php) in your web browser.

+Google Cloud Compute Engine PHP Samples - Instances
+===================================================
+
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=compute/cloud-client/instances
+
+This directory contains samples for calling [Google Cloud Compute Engine][compute] APIs
+from PHP. Specifically, they show how to manage your Compute Engine [instances][instances].
+
+[compute]: https://cloud.google.com/compute/docs/apis
+[instances]: https://cloud.google.com/compute/docs/instances/stop-start-instance
+
+## Setup
+
+### Authentication
+
+Authentication is typically done through [Application Default Credentials][adc]
+which means you do not have to change the code to authenticate as long as
+your environment has credentials. You have a few options for setting up
+authentication:
+
+1. When running locally, use the [Google Cloud SDK][google-cloud-sdk]
+
+        gcloud auth application-default login
+
+1. When running on App Engine or Compute Engine, credentials are already
+   set. However, you may need to configure your Compute Engine instance
+   with [additional scopes][additional_scopes].
+
+1. You can create a [Service Account key file][service_account_key_file]. This file can be used to
+   authenticate to Google Cloud Platform services from any environment. To use
+   the file, set the ``GOOGLE_APPLICATION_CREDENTIALS`` environment variable to
+   the path to the key file, for example:
+
+        export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account.json
+
+[adc]: https://cloud.google.com/docs/authentication#getting_credentials_for_server-centric_flow
+[additional_scopes]: https://cloud.google.com/compute/docs/authentication#using
+[service_account_key_file]: https://developers.google.com/identity/protocols/OAuth2ServiceAccount#creatinganaccount
+
+## Install Dependencies
+
+1. **Install dependencies** using [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+
+1. Create a [service account](https://cloud.google.com/iam/docs/creating-managing-service-accounts#creating).
+
+1. [Download the json key file](https://cloud.google.com/iam/docs/creating-managing-service-account-keys#getting_a_service_account_key)
+   of the service account.
+
+1. Set the `GOOGLE_APPLICATION_CREDENTIALS` environment variable pointing to that file.
+
+## Samples
+
+To run the Compute samples, run any of the files in `src/` on the CLI to print
+the usage instructions:
+
+```
+$ php src/list_instances.php
+
+Usage: list_instances.php $projectId $zone
+
+  @param string $projectId Your Google Cloud project ID.
+  @param string $zone The zone to create the instance in (e.g. "us-central1-a")
+```
+
+### Create an instance
+
+```
+$ php src/create_instance.php $YOUR_PROJECT_ID "us-central1-a" "my-new-instance-name"
+Created instance my-new-instance-name
+```
+
+### List instances
+
+```
+$ php src/list_instances.php $YOUR_PROJECT_ID "us-central1-a"
+Instances for YOUR_PROJECT_ID (us-central1-a)
+ - my-new-instance-name
+```
+
+### List all instances
+
+```
+$ php src/list_all_instances.php $YOUR_PROJECT_ID
+All instances for YOUR_PROJECT_ID
+Zone - zones/us-central1-a
+ - my-new-instance-name
+Zone - zones/us-central1-b
+ - my-new-instance-name-2
+ - my-new-instance-name-3
+```
+
+### Stop an instance
+
+```
+$ php src/stop_instance.php $YOUR_PROJECT_ID "us-central1-a" "my-new-instance-name"
+Instance my-new-instance-name stopped successfully
+```
+
+### Start an instance
+
+```
+$ php src/start_instance.php $YOUR_PROJECT_ID "us-central1-a" "my-new-instance-name"
+Instance my-new-instance-name started successfully
+```
+
+### Start an instance with encrypted disk
+
+```
+$ php src/start_instance_with_encryption_key.php $YOUR_PROJECT_ID "us-central1-a" "my-new-instance-name" $ENC_KEY
+Instance my-new-instance-name started successfully
+```
+
+### Reset an instance
+
+```
+$ php src/reset_instance.php $YOUR_PROJECT_ID "us-central1-a" "my-new-instance-name"
+Instance my-new-instance-name reset successfully
+```
+
+### Delete an instance
+
+```
+$ php src/delete_instance.php $YOUR_PROJECT_ID "us-central1-a" "my-new-instance-name"
+Deleted instance my-new-instance-name
+```
+
+### Set usage export bucket
+
+```
+$ php src/set_usage_export_bucket.php $YOUR_PROJECT_ID "my-gcs-bucket-name" "my-report-name-prefix"
+```
+
+### Get usage export bucket
+
+```
+$ php src/get_usage_export_bucket.php $YOUR_PROJECT_ID
+```
+
+### Disable usage export bucket
+
+```
+$ php src/disable_usage_export_bucket.php $YOUR_PROJECT_ID
+```
+
+## Troubleshooting
+
+If you get the following error, set the environment variable `GCLOUD_PROJECT` to your project ID:
+
+```
+[Google\Cloud\Core\Exception\GoogleException]
+No project ID was provided, and we were unable to detect a default project ID.
+```
+
+## The client library
+
+This sample uses the [Google Cloud Compute Client Library for PHP][google-cloud-php-compute].
+You can read the documentation for more details on API usage and use GitHub
+to [browse the source][google-cloud-php-source] and [report issues][google-cloud-php-issues].

+# Dialogflow: PHP Samples
+
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=dialogflow
+
+## Description
+
+This command-line application demonstrates how to invoke Dialogflow
+API from PHP.
+
+## Before you begin
+1. Follow the first 2 steps of [this quickstart](https://cloud.google.com/dialogflow-enterprise/docs/quickstart-api).
+Feel free to stop after you've created an agent.
+
+2. This sample comes with a [sample agent](https://github.com/GoogleCloudPlatform/php-docs-samples/blob/main/dialogflow/resources/RoomReservation.zip) which you can use to try the samples with. Follow the instructions on [this page](https://dialogflow.com/docs/best-practices/import-export-for-versions) to import the agent from the [console](https://console.dialogflow.com/api-client).
+> WARNING: Importing the sample agent will add intents and entities to your Dialogflow agent. You might want to use a different Google Cloud Platform Project, or export your Dialogflow agent before importing the sample agent to save a version of your agent before the sample agent was imported.
+
+3.  Clone the repo and cd into this directory
+```
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/dialogflow
+```
+
+4. Follow [this guide](https://cloud.google.com/php/grpc) to install gRPC for PHP.
+
+5.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).

+## The client library
+
+This sample uses the [Dialogflow Client Library for PHP][google-cloud-php-dialogflow].
+You can read the documentation for more details on API usage and use GitHub
+to [browse the source][google-cloud-php-source] and [report issues][google-cloud-php-issues].
+
+## Troubleshooting
+
+If you get the following error, set the environment variable `GCLOUD_PROJECT` to your project ID:
+
+```
+[Google\Cloud\Core\Exception\GoogleException]
+No project ID was provided, and we were unable to detect a default project ID.
+```
+
+If you have not set a timezone you may get an error from php. This can be resolved by:
+
+  1. Finding where the php.ini is stored by running `php -i | grep 'Configuration File'`
+  1. Finding out your timezone from the list on this page: http://php.net/manual/en/timezones.php
+  1. Editing the php.ini file (or creating one if it doesn't exist)
+  1. Adding the timezone to the php.ini file e.g., adding the following line: `date.timezone = "America/Los_Angeles"`

+## Troubleshooting
+
+### bcmath extension missing
 
+If you see an error like this:
+
+```
+PHP Fatal error:  Uncaught Error: Call to undefined function Google\Protobuf\Internal\bccomp() in /usr/local/google/home/crwilson/github/GoogleCloudPlatform/php-docs-samples/dlp/vendor/google/protobuf/src/Google/Protobuf/Internal/Message.php:986
+```
+
+You may need to install the bcmath PHP extension.
+e.g. (may depend on your php version)
+```
+$ sudo apt-get install php8.1-bcmath
+```

Illustrates using the InspectConfig property for the purpose of scanning a medical database for patient names. You can use Cloud DLP's built-in PERSON_NAME infoType detector, but that causes Cloud DLP to match on all names of people, not just names of patients. To fix this, you can include a hotword rule that looks for the word "patient" within a certain character proximity from the first character of potential matches. You can then assign findings that match this pattern a likelihood of "very likely," since they correspond to your special criteria. Setting the minimum likelihood to VERY_LIKELY within InspectConfig ensures that only matches to this configuration are returned in findings.

+# Google Cloud Document AI Samples
+
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=documentai
+
+These samples show how to use the [Google Cloud Document AI][document-ai]
+
+This repository contains samples that use the [Cloud Document AI Client
+Library for PHP][google-cloud-php-documentai] to make REST calls as well as
+contains samples using the more-efficient (though sometimes more
+complex) [GRPC][grpc] API. The GRPC API also allows streaming requests.
+
+## Installation
+
+Install the dependencies for this library via [composer](https://getcomposer.org)
+
+    $ cd /path/to/php-docs-samples/documentai
+    $ composer install
+
+Configure your project using [Application Default Credentials][adc]
+
+    $ export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credentials.json
+
+## Usage
+
+Run `php src/SNIPPET_NAME.php`. The usage will print for each if no arguments
+are provided:
+
+## Troubleshooting
+
+If you get the following error, set the environment variable `GCLOUD_PROJECT` to your project ID:
+
+```
+[Google\Cloud\Core\Exception\GoogleException]
+No project ID was provided, and we were unable to detect a default project ID.
+```
+
+If you have not set a timezone you may get an error from php. This can be resolved by:
+
+  1. Finding where the php.ini is stored by running php -i | grep 'Configuration File'
+  1. Finding out your timezone from the list on this page: http://php.net/manual/en/timezones.php
+  1. Editing the php.ini file (or creating one if it doesn't exist)
+  1. Adding the timezone to the php.ini file e.g., adding the following line: date.timezone = "America/Los_Angeles"

+[error-reporting]: https://cloud.google.com/error-reporting/docs/setup/php
+
+`quickstart.php` and `src/report_error.php` are simple command-line programs to
+demonstrate logging exceptions, errors, and PHP fatal errors to
+Stackdriver Error Reporting.
 
 # Installation
 
 1. To use this sample, you must first [enable the Stackdriver Error Reporting API][0]
 1. Next, **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md):
-    1. Run `php composer.phar install --ignore-platform-reqs` (if composer is installed locally) or `composer install --ignore-platform-reqs`
+    1. Run `php composer.phar install` (if composer is installed locally) or `composer install`
     (if composer is installed globally).
     ```sh
-    composer install --ignore-platform-reqs
+    composer install
+    ```
+    1. To use the [gRPC PHP Extension][php_grpc], which will be more performant than
+    REST/HTTP,
+    install and enable the gRPC extension using PECL:
+    ```sh
+    pecl install grpc
     ```
-    1. If the [gRPC PHP Extension][php_grpc] is enabled for your version of PHP,
-    install your dependencies without the `--ignore-platform-reqs` flag. **Note**
-    some samples in `error_reporting.php` require gRPC.
 1. Create a service account in the [Service Account section of the Cloud Console][2]
 1. Download the JSON key file of the service account.
 1. Set `GOOGLE_APPLICATION_CREDENTIALS` environment variable to point to that file.

+Throwing a test exception. You can view the message at https://console.cloud.google.com/errors.
 ```
 
-View [Stackdriver Error Reporting][1] in the Cloud Console to see the logged

-# Running error_reporting.php
+# Running src/report_error.php
 
-Run the sample:
+This sample shows how to report an error by creating a `ReportedErrorEvent`. The
+`ReportedErrorEvent` object gives you more control over how the error appears
+and the details associated with it.
 
-```sh
-$ php error_reporting.php report YOUR_PROJECT_ID
-Reported an error to Stackdriver
-```
-
-For an example of how to register the Stackdriver exception handler in your custom application, see
-[src/register_exception_handler.php](src/register_exception_handler.php). You can test this out
-using the samples:
+Run the sample:
 
 ```sh
-# Test registering an exception handler and then throwing a PHP Fatal Error
-$ php error_reporting.php test-exception-handler YOUR_PROJECT_ID --fatal
-Triggering a PHP Fatal Error by eval-ing a syntax error...
+$ php src/report_error.php YOUR_PROJECT_ID "This is a test message"
+Reported an exception to Stackdriver
 ```
 
-For more granular control over your error reporting, and better performance, you can use the gRPC
-library to throw errors. Follow the instructions to install and enable the
-[gRPC PHP Extension][php_grpc]. Now run the gRPC example in `error_reporting.php`:
-
-```sh
-$ php error_reporting.php report-grpc YOUR_PROJECT_ID
-Reported an error to Stackdriver
-```

+# Eventarc – Generic – PHP Sample
+
+This directory contains a sample for receiving a generic event using Cloud Run
+and Eventarc with PHP. For testing purposes, we use Cloud Pub/Sub as an event
+source for our sample.
+
+## Setup
+
+1. [Set up for Cloud Run development](https://cloud.google.com/run/docs/setup)
+
+1. Install the gcloud command-line tool beta components:
+
+    ```sh
+    gcloud components install beta
+    ```
+
+1. Set the following gcloud configurations, where `PROJECT_ID` is your Google
+   Cloud project ID:
+
+    ```sh
+    gcloud config set project PROJECT_ID
+    gcloud config set run/region us-central1
+    gcloud config set run/platform managed
+    gcloud config set eventarc/location us-central1
+    ```
+
+1. [Enable the Cloud Run, Cloud Logging, Cloud Build, Pub/Sub, and Eventarc APIs][enable_apis_url].
+
+1. Clone this repository and navigate to this directory:
+
+    ```sh
+    git clone https://github.com/GoogleCloudPlatform/php-docs-samples.git
+    cd php-docs-samples/eventarc/generic
+    ```
+
+## Run the sample locally
+
+1. [Install docker locally](https://docs.docker.com/install/)
+
+1. [Build the container locally](https://cloud.google.com/run/docs/building/containers#building_locally_and_pushing_using_docker):
+
+    ```sh
+    docker build --tag eventarc-generic .
+    ```
+
+1. [Run containers locally](https://cloud.google.com/run/docs/testing/local)
+
+    With the built container:
+
+    ```sh
+    PORT=8080 && docker run --rm -p 8080:${PORT} -e PORT=${PORT} eventarc-generic
+    ```
+
+    Test the web server with `cURL`:
+
+    ```sh
+    curl -XPOST localhost:8080 -d '{ "test": "foo" }'
+    ```
+
+    Observe the output logs your HTTP request:
+
+    ```
+    Event received!
+
+    HEADERS:
+    Host: localhost:8080
+    User-Agent: curl/7.64.1
+    Accept: */*
+    Content-Length: 17
+    Content-Type: application/x-www-form-urlencoded
+
+    BODY:
+    { "test": "foo" }
+    ```
+
+    Exit the container with `Ctrl-D`.
+
+## Run the sample on Cloud Run
+
+1. [Build the container using Cloud Build](https://cloud.google.com/run/docs/building/containers#builder)
+
+    ```sh
+    gcloud builds submit --tag gcr.io/$(gcloud config get-value project)/eventarc-generic-php
+    ```
+
+1. [Deploy the container](https://cloud.google.com/run/docs/deploying#service)
+
+    ```sh
+    gcloud run deploy eventarc-generic-php \
+      --image gcr.io/$(gcloud config get-value project)/eventarc-generic-php \
+      --allow-unauthenticated
+    ```
+
+    The command line will display the service URL when deployment is complete.
+
+### Create an Eventarc Trigger
+
+1. Create an Eventarc trigger for your Cloud Run service
+
+    ```sh
+    gcloud beta eventarc triggers create eventarc-generic-php-trigger \
+      --destination-run-service=eventarc-generic-php \
+      --destination-run-region=us-central1 \
+      --matching-criteria="type=google.cloud.pubsub.topic.v1.messagePublished"
+    ```
+
+1. Confirm the trigger was successfully created, run:
+
+    ```sh
+    gcloud beta eventarc triggers describe eventarc-generic-php-trigger
+    ```
+
+    > Note: It can take up to 10 minutes for triggers to be fully functional.
+
+### Send an Event
+
+1. Find and set the Pub/Sub topic as an environment variable:
+
+    ```sh
+    export RUN_TOPIC=$(gcloud beta eventarc triggers describe eventarc-generic-php-trigger \
+    --format='value(transport.pubsub.topic)')
+    ```
+
+1. Send a message to the Pub/Sub topic to generate an event:
+
+    ```sh
+    gcloud pubsub topics publish $RUN_TOPIC --message="Hello, PHP"
+    ```
+
+    The event is sent to the Cloud Run (fully managed) service, which logs the generic HTTP request.
+
+### View an Event in Logs
+
+1. To view the event, go to the Cloud Run (fully managed) service logs:
+
+    1. Go to the [Google Cloud Console](https://console.cloud.google.com/run).
+
+    1. Click the `eventarc-generic-php` service.
+
+    1. Select the **Logs** tab.
+
+        > Logs might take a few moments to appear. If you don't see them immediately, check again after a few moments.
+
+    1. Look for the log message "Event received!" followed by other log entries. This log entry indicates a request was sent by Eventarc to your Cloud Run service.
+
+### Cleaning Up
+
+To clean up, delete the resources created above:
+
+1. Delete the Cloud Build container:
+
+    ```sh
+    gcloud container images delete gcr.io/$(gcloud config get-value project)/eventarc-generic-php
+    ```
+
+1. Delete the Cloud Run service:
+
+    ```sh
+    gcloud run services delete eventarc-generic-php
+    ```
+
+1. Delete the Eventarc trigger:
+
+    ```sh
+    gcloud beta eventarc triggers delete eventarc-generic-php-trigger
+    ```
+
+1. Delete the Pub/Sub topic:
+
+    ```sh
+    gcloud pubsub topics delete $RUN_TOPIC
+    ```

+# Google Cloud Firestore API Samples
+
+These samples show how to use the [Google Cloud Firestore API][cloud-firestore-api] to store and query data.
+
+[cloud-firestore-api]: https://cloud.google.com/firestore/docs/quickstart-servers
+
+## Setup
+
+### Prerequisites
+
+1. Open the [Firebase Console][firebase-console] and create a new project. (You can't use both Cloud Firestore and Cloud Datastore in the same project, which might affect apps using App Engine. Try using Cloud Firestore with a different project if this is the case).
+
+1. In the Database section, click Try Firestore Beta.
+
+1. Click Enable.
+
+[firebase-console]: https://console.firebase.google.com
+
+
+### Authentication
+
+Authentication is typically done through [Application Default Credentials][adc]
+which means you do not have to change the code to authenticate as long as
+your environment has credentials. You have a few options for setting up
+authentication:
+
+1. When running locally, use the [Google Cloud SDK][google-cloud-sdk]
+
+        gcloud auth application-default login
+
+1. When running on App Engine or Compute Engine, credentials are already
+   set-up. However, you may need to configure your Compute Engine instance
+   with [additional scopes][additional_scopes].
+
+1. You can create a [Service Account key file][service_account_key_file]. This file can be used to
+   authenticate to Google Cloud Platform services from any environment. To use
+   the file, set the ``GOOGLE_APPLICATION_CREDENTIALS`` environment variable to
+   the path to the key file, for example:
+
+        export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account.json
+
+[adc]: https://cloud.google.com/docs/authentication#getting_credentials_for_server-centric_flow
+[additional_scopes]: https://cloud.google.com/compute/docs/authentication#using
+[service_account_key_file]: https://developers.google.com/identity/protocols/OAuth2ServiceAccount#creatinganaccount
+
+## Install Dependencies
+
+1. [Enable the Cloud Firestore API](https://console.cloud.google.com/flows/enableapi?apiid=firestore.googleapis.com).
+
+1. **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+
+1. Create a service account at the
+[Service account section in the Cloud Console](https://console.cloud.google.com/iam-admin/serviceaccounts/)
+
+1. Download the json key file of the service account.
+
+1. Set `GOOGLE_APPLICATION_CREDENTIALS` environment variable pointing to that file.
+
+## Samples
+
+To run the Firestore Samples, run any of the files in `src/` on the CLI:
+
+```
+$ php src/setup_dataset.php
+
+Usage: setup_dataset.php $projectId
+
+    @param string $projectId The Google Cloud Project ID
+```
+
+## The client library
+
+This sample uses the [Firestore Client Library for PHP][google-cloud-php-firestore].
+You can read the documentation for more details on API usage and use GitHub
+to [browse the source][google-cloud-php-source] and [report issues][google-cloud-php-issues].
+
+## Troubleshooting
+
+If you get the following error, set the environment variable `GCLOUD_PROJECT` to your project ID:
+
+```
+[Google\Cloud\Core\Exception\GoogleException]
+No project ID was provided, and we were unable to detect a default project ID.
+```
+
+If you have not set a timezone you may get an error from php. This can be resolved by:
+
+  1. Finding where the php.ini is stored by running `php -i | grep 'Configuration File'`
+  1. Finding out your timezone from the list on this page: http://php.net/manual/en/timezones.php
+  1. Editing the php.ini file (or creating one if it doesn't exist)
+  1. Adding the timezone to the php.ini file e.g., adding the following line: `date.timezone = "America/Los_Angeles"`

+Every highlight needs it's own personal shadow. In your world you can create anything you desire. Be so very light. Be a gentle whisper. You don't have to be crazy to do this but it does help.
+
+You can do it. Making all those little fluffies that live in the clouds. Put your feelings into it, your heart, it's your world. If we're gonna walk though the woods, we need a little path. Let's get crazy.
+
+Brown is such a nice color. Follow the lay of the land. It's most important. This piece of canvas is your world. Talk to trees, look at the birds. Whatever it takes.
+
+Volunteering your time; it pays you and your whole community fantastic dividends. Just a little indication. Van Dyke Brown is a very nice brown, it's almost like a chocolate brown. Work on one thing at a time. Don't get carried away - we have plenty of time. Now then, let's play.
+
+I spend a lot of time walking around in the woods and talking to trees, and squirrels, and little rabbits and stuff. Let your heart be your guide. We start with a vision in our heart, and we put it on canvas.
+
+This painting comes right out of your heart. You gotta think like a tree. It's hard to see things when you're too close. Take a step back and look. There are no mistakes. You can fix anything that happens. Be brave. Now we don't want him to get lonely, so we'll give him a little friend.
+
+I'm gonna add just a tiny little amount of Prussian Blue. The more we do this - the more it will do good things to our heart. Working it up and down, back and forth.

 These samples show how to use the [Google Cloud Identity Aware Proxy][iap]. Cloud Identity-Aware Proxy (Cloud IAP) controls access to your cloud applications running on Google Cloud Platform. Cloud IAP works by verifying a user’s identity and determining if that user should be allowed to access the application.
 
 If this is your first time using the Google Cloud Identity Aware Proxy, try out our [quickstart tutorial][iap-quickstart].

 # Google Cloud KMS API Samples
 
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=kms
+
 ## Description
 
-These samples show how to use the [Google Cloud KMS API]
-(https://cloud.google.com/kms/).
+These samples demonstrate how to invoke [Google Cloud KMS][kms] from PHP.
 
 ## Build and Run
-1.  **Enable APIs** - [Enable the KMS API](https://console.cloud.google.com/flows/enableapi?apiid=cloudkms.googleapis.com)
+
+1.  **Enable APIs** - [Enable the KMS
+    API](https://console.cloud.google.com/flows/enableapi?apiid=cloudkms.googleapis.com)
     and create a new project or select an existing project.
-2.  **Activate your Credentials** - If you do not already have an active set of credentials, create and download a [JSON Service Account key](https://pantheon.corp.google.com/apis/credentials/serviceaccountkey). Set the environment variable `GOOGLE_APPLICATION_CREDENTIALS` as the path to the downloaded JSON file.
-4.  **Clone the repo** and cd into this directory
 
-    ```
+1.  **Download The Credentials** - Click "Go to credentials" after enabling the
+    APIs. Click "New Credentials" and select "Service Account Key". Create a new
+    service account, use the JSON key type, and select "Create". Once
+    downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS` to
+    the path of the JSON key that was downloaded.
+
+1.  **Clone the repo** and cd into this directory
+
+    ```text
     $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
     $ cd php-docs-samples/kms
-```
-5.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
-    Run `php composer.phar install` (if composer is installed locally) or `composer install`
-    (if composer is installed globally).
-6.  Run `php kms.php`. The following commands are available:
-
-    ```sh
-    encryption    Manage encryption for KMS
-    iam           Manage IAM for KMS
-    key           Manage keys for KMS
-    keyring       Manage keyrings for KMS
-    version       Manage key versions for KMS
-```
-7. Run `php kms.php COMMAND --help` to print information about the usage of each command.
+    ```
+
+1.  **Install dependencies** via [Composer][install-composer]. If composer is
+    installed locally:
+
+    ```text
+    $ php composer.phar install
+    ```
+
+    If composer is installed globally:
+
+    ```text
+    $ composer install
+    ```
+
+1.  Execute the snippets in the [src/](src/) directory by running:
+
+    ```text
+    $ php src/SNIPPET_NAME.php
+    ```
+
+    The usage will print for each if no arguments are provided.
+
+See the [Cloud KMS Documentation](https://cloud.google.com/kms/docs) for more
+information.

+# Google Cloud Live Stream PHP Sample Application
+
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=media/livestream
+
+## Description
+
+This simple command-line application demonstrates how to invoke
+[Cloud Live Stream API][livestream-api] from PHP.
+
+[livestream-api]: https://cloud.google.com/livestream/docs/reference/libraries
+
+## Build and Run
+1.  **Enable APIs** - [Enable the Live Stream API](
+    https://console.cloud.google.com/flows/enableapi?apiid=livestream.googleapis.com)
+    and create a new project or select an existing project.
+2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click
+    "New Credentials"
+    and select "Service Account Key". Create a new service account, use the JSON key type, and
+    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
+    to the path of the JSON key that was downloaded.
+3.  **Clone the repo** and cd into this directory
+```
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd media/livestream
+```
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+5.  Execute the snippets in the [src/](src/) directory by running
+    `php src/SNIPPET_NAME.php`. The usage will print for each if no arguments
+    are provided:
+    ```sh
+    $ php src/create_input.php
+    Usage: create_input.php $callingProjectId $location $inputId
+
+        @param string $callingProjectId     The project ID to run the API call under
+        @param string $location             The location of the input
+        @param string $inputId              The name of the input to be created
+
+    $ php create_input.php my-project us-central1 my-input
+    Input: projects/123456789012/locations/us-central1/inputs/my-input
+    ```
+
+See the [Live Stream Documentation](https://cloud.google.com/livestream/docs/) for more information.

+# Google Transcoder PHP Sample Application
+
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=media/transcoder
+
+## Description
+
+This simple command-line application demonstrates how to invoke
+[Google Transcoder API][transcoder-api] from PHP.
+
+[transcoder-api]: https://cloud.google.com/transcoder/docs/reference/libraries
+
+## Build and Run
+1.  **Enable APIs** - [Enable the Transcoder API](
+    https://console.cloud.google.com/flows/enableapi?apiid=transcoder.googleapis.com)
+    and create a new project or select an existing project.
+2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click
+    "New Credentials"
+    and select "Service Account Key". Create a new service account, use the JSON key type, and
+    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
+    to the path of the JSON key that was downloaded.
+3.  **Clone the repo** and cd into this directory
+```
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd media/transcoder
+```
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+5.  Execute the snippets in the [src/](src/) directory by running
+    `php src/SNIPPET_NAME.php`. The usage will print for each if no arguments
+    are provided:
+    ```sh
+    $ php php src/create_job_from_ad_hoc.php
+    Usage: create_job_from_ad_hoc.php $projectId $location $inputUri $outputUri
+
+      @param string $projectId The ID of your Google Cloud Platform project.
+      @param string $location The location of the job.
+      @param string $inputUri Uri of the video in the Cloud Storage bucket.
+      @param string $outputUri Uri of the video output folder in the Cloud Storage bucket.
+
+
+    $ php create_job_from_ad_hoc.php my-project us-central1 gs://my-bucket/input.mp4 gs://my-bucket/adhoc/
+    Job: projects/657323817858/locations/us-central1/jobs/13beaa6b-5a33-4a86-b280-04b524546291
+    ```
+
+See the [Transcoder Documentation](https://cloud.google.com/transcoder/docs/) for more information.
+
+## Troubleshooting
+
+### bcmath extension missing
+
+If you see an error like this:
+
+```
+PHP Fatal error:  Uncaught Error: Call to undefined function Google\Protobuf\Internal\bcsub()
+```
+
+You need to install the BC-Math extension.
+
+See the [Troubleshooting guide](https://cloud.google.com/transcoder/docs/troubleshooting) for more information.

+# Google Cloud Video Stitcher PHP Sample Application
+
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=media/videostitcher
+
+## Description
+
+This simple command-line application demonstrates how to invoke
+[Cloud Video Stitcher API][videostitcher-api] from PHP.
+
+[videostitcher-api]: https://cloud.google.com/video-stitcher/docs/reference/libraries
+
+## Build and Run
+1.  **Enable APIs** - [Enable the Video Stitcher API](
+    https://console.cloud.google.com/flows/enableapi?apiid=videostitcher.googleapis.com)
+    and create a new project or select an existing project.
+2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click
+    "New Credentials"
+    and select "Service Account Key". Create a new service account, use the JSON key type, and
+    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
+    to the path of the JSON key that was downloaded.
+3.  **Clone the repo** and cd into this directory
+```
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd media/videostitcher
+```
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`

+# Google Parameter Manager PHP Sample Application
+
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=parametermanager
+
+## Description
+
+This simple command-line application demonstrates how to invoke
+[Google Parameter Manager][parametermanager] from PHP.
+
+## Build and Run
+
+1.  **Enable APIs** - [Enable the Parameter Manager
+    API](https://console.cloud.google.com/apis/enableflow?apiid=parametermanager.googleapis.com)
+    and create a new project or select an existing project.
+
+1.  **Download The Credentials** - Click "Go to credentials" after enabling the
+    APIs. Click "New Credentials" and select "Service Account Key". Create a new
+    service account, use the JSON key type, and select "Create". Once
+    downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS` to
+    the path of the JSON key that was downloaded.
+
+1.  **Clone the repo** and cd into this directory
+
+    ```text
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/parametermanager
+    ```
+
+1.  **Install dependencies** via [Composer][install-composer]. If composer is
+    installed locally:
+
+
+    ```text
+    $ php composer.phar install
+    ```
+
+    If composer is installed globally:
+
+    ```text
+    $ composer install
+    ```
+
+1.  Execute the snippets in the [src/](src/) directory by running:
+
+    ```text
+    $ php src/SNIPPET_NAME.php
+    ```
+
+    The usage will print for each if no arguments are provided.
+
+See the [Parameter Manager Documentation](https://cloud.google.com/secret-manager/parameter-manager/docs/overview) for more information.

 ## Description
 
-This simple command-line application demonstrates how to invoke Google Pub\Sub from PHP.
-
-## Build and Run
-1.  **Enable APIs** - [Enable the Pub\Sub API](https://console.cloud.google.com/flows/enableapi?apiid=pubsub)
-    and create a new project or select an existing project.
-2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click "New Credentials"
-    and select "Service Account Key". Create a new service account, use the JSON key type, and
-    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
-    to the path of the JSON key that was downloaded.
-3.  **Clone the repo** and cd into this directory
-
-    ```sh
-    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
-    $ cd php-docs-samples/pubsub/api
-```
-4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+This simple command-line application demonstrates how to invoke
+[Google Pub\Sub][pubsub] from PHP.
+
+[pubsub]: https://cloud.google.com/pubsub/docs/quickstart-client-libraries
+
+## Setup
+
+### Authentication
+
+Authentication is typically done through [Application Default Credentials][adc]
+which means you do not have to change the code to authenticate as long as
+your environment has credentials. You have a few options for setting up
+authentication:
+
+1. When running locally, use the [Google Cloud SDK][google-cloud-sdk]
+
+        gcloud auth application-default login
+
+1. When running on App Engine or Compute Engine, credentials are already
+   set-up. However, you may need to configure your Compute Engine instance
+   with [additional scopes][additional_scopes].
+
+1. You can create a [Service Account key file][service_account_key_file]. This file can be used to
+   authenticate to Google Cloud Platform services from any environment. To use
+   the file, set the ``GOOGLE_APPLICATION_CREDENTIALS`` environment variable to
+   the path to the key file, for example:
+
+        export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account.json
+
+[adc]: https://cloud.google.com/docs/authentication#getting_credentials_for_server-centric_flow
+[additional_scopes]: https://cloud.google.com/compute/docs/authentication#using
+[service_account_key_file]: https://developers.google.com/identity/protocols/OAuth2ServiceAccount#creatinganaccount
+
+## Install Dependencies
+
+1. Ensure the [gRPC PHP Extension][php_grpc] is installed and enabled on your machine.
+1. [Enable the Cloud Pub/Sub API](https://console.cloud.google.com/flows/enableapi?apiid=pubsub.googleapis.com).
+
+1. **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
     Run `php composer.phar install` (if composer is installed locally) or `composer install`
     (if composer is installed globally).
-5.  Run `php pubsub.php`. The following commands are available:
 
-    ```sh
-    iam           Manage IAM for Pub\Sub
-    subscription  Manage subscriptions for Pub\Sub
-    topic         Manage topics for Pub\Sub
+1. Create a service account at the
+[Service account section in the Cloud Console](https://console.cloud.google.com/iam-admin/serviceaccounts/)
+
+1. Download the json key file of the service account.
+
+1. Set `GOOGLE_APPLICATION_CREDENTIALS` environment variable pointing to that file.
+
+## Samples
+
+To run the Pub/Sub Samples, run any of the files in `src/` on the CLI:
+
+```
+$ php src/create-topic.php
+
+Usage: create_topic.php $projectId $topicName
+
+	@param string $projectId  The Google project ID.
+	@param string $topicName  The Pub/Sub topic name.
+```
+
+## PHPUnit Tests
+
+At this time, the GitHub actions in this repo fail to run the tests written in this folder. The developer is responsible for locally running and confirming their samples and corresponding tests.
+
+### PubSub Emulator
+Some tests in the pubsubTest.php requires PubSub emulator. These tests start with ```$this->requireEnv('PUBSUB_EMULATOR_HOST')```.
+
+#### Prerequisites
+- Python
+```
+xcode-select --install
+brew install pyenv
+pyenv install <version>
+python3 --version
+```
+- JDK
+```
+brew install openjdk
+export JAVA_HOME=<path to openjdk folder>
+export PATH="$JAVA_HOME/bin:$PATH"
 ```
-6. Run `php pubsub.php COMMAND --help` to print information about the usage of each command.
 
-## Contributing changes
+Once python, JDK, and GCloud CLI are installed, follow [these instructions](https://cloud.google.com/pubsub/docs/emulator) to run the emulator.
+
+### Setting up environment variables
+Open a new tab in terminal, separate from the one running your emulator.
+
+```
+// php-docs-samples/testing folder
+$ cd ../../../testing
+
+$ export GOOGLE_PROJECT_ID=<project id>
+$ export GOOGLE_PUBSUB_TOPIC=<topic name>
+$ export GOOGLE_PUBSUB_STORAGE_BUCKET=<bucket name>
+$ export GOOGLE_PUBSUB_SUBSCRIPTION=<subscription name>
+
+// only set if your test requires the emulator
+$ export PUBSUB_EMULATOR_HOST=localhost:<emulator port>
+
+// unset the PUBSUB emulator host variable if you want to run a test that doesn't require an emulator
+$ unset PUBSUB_EMULATOR
+```
+
+### Running the tests
+Run your test(s) like so in the same terminal tab that you set your env variables in the previous step.
+
+```
+// Run all tests in pubsubTest.php. --verbose tag is recommended to see any issues or stack trace
+$ php-docs-samples/testing/vendor/bin/phpunit ../pubsub/api/test/pubsubTest.php --verbose
+
+// Run a single test in pubsubTest.php
+$ php-docs-samples/testing/vendor/bin/phpunit ../pubsub/api/test/pubsubTest.php --filter testSubscriptionPolicy --verbose
+```
+
+## Fixing Styling Errors
+If you create a PR and the Lint / styles (pull_request) check fails, this is a quick fix.
+
+```
+$ php-docs-samples/testing/vendor/bin/php-cs-fixer fix <path to your file>
+```
+
+## Troubleshooting
+
+If you get the following error, set the environment variable `GCLOUD_PROJECT` to your project ID:
+
+```
+[Google\Cloud\Core\Exception\GoogleException]
+No project ID was provided, and we were unable to detect a default project ID.
+```

+# Google reCAPTCHA Enterprise PHP Sample Application
+
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=recaptcha
+
+## Description
+
+This simple command-line application demonstrates how to invoke
+[Google reCAPTCHA Enterprise][recaptcha-enterprise] from PHP.
+
+## Build and Run
+
+1.  **Enable APIs** - [Enable the reCAPTCHA Enterprise
+    API](https://console.cloud.google.com/flows/enableapi?apiid=recaptchaenterprise.googleapis.com)
+    and create a new project or select an existing project.
+
+1.  **Download The Credentials** - Click "Go to credentials" after enabling the
+    APIs. Click "New Credentials" and select "Service Account Key". Create a new
+    service account, use the JSON key type, and select "Create". Once
+    downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS` to
+    the path of the JSON key that was downloaded.
+
+1.  **Clone the repo** and cd into this directory
+
+    ```text
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/recaptcha
+    ```
+
+1.  **Install dependencies** via [Composer][install-composer]. If composer is
+    installed locally:
+
+    ```text
+    $ php composer.phar install
+    ```
+
+    If composer is installed globally:
+
+    ```text
+    $ composer install
+    ```
+
+1.  Execute the snippets in the [src/](src/) directory by running:
+
+    ```text
+    $ php src/SNIPPET_NAME.php
+    ```
+
+    The usage will print for each if no arguments are provided.
+
+See the [reCAPTCHA Enterprise Documentation](https://cloud.google.com/recaptcha-enterprise/docs) for more information.

+# Google Cloud Run PHP Samples
+
+[Cloud Run][run_docs] runs stateless [containers](https://cloud.google.com/containers/) on a fully managed environment or in your own GKE cluster.
+
+## Samples
+
+|                 Sample                  |        Description       |     Deploy    |
+| --------------------------------------- | ------------------------ | ------------- |
+|[Hello World][helloworld]  | Quickstart | [<img src="https://storage.googleapis.com/cloudrun/button.svg" alt="Run on Google Cloud" height="30"/>][run_button_helloworld] |
+|[Laravel][laravel]                        | Deploy Laravel on Cloud Run                | -|
+|[Multi-container][multicontainer]          | Multi-container samples (i.e nginx) | -|
+
+
+For more Cloud Run samples beyond PHP, see the main list in the [Cloud Run Samples repository](https://github.com/GoogleCloudPlatform/cloud-run-samples).
+
+## Setup
+
+1. [Set up for Cloud Run development](https://cloud.google.com/run/docs/setup)
+
+2. Clone this repository:
+
+    ```sh
+    git clone https://github.com/GoogleCloudPlatform/php-docs-samples.git
+    cd php-docs-samples/run
+    ```
+
+## How to run a sample locally
+
+1. [Install docker locally](https://docs.docker.com/install/)
+
+2. [Build the sample container](https://cloud.google.com/run/docs/building/containers#building_locally_and_pushing_using_docker):
+
+    ```sh
+    export SAMPLE='helloworld'
+    cd $SAMPLE
+    docker build --tag $SAMPLE .
+    ```
+
+3. [Run containers locally](https://cloud.google.com/run/docs/testing/local)
+
+    With the built container:
+
+    ```sh
+    PORT=8080 && docker run --rm -p 8080:${PORT} -e PORT=${PORT} $SAMPLE
+    ```
+
+    Overriding the built container with local code:
+
+    ```sh
+    PORT=8080 && docker run --rm \
+        -p 8080:${PORT} -e PORT=${PORT} \
+        -v $PWD:/usr/src/app $SAMPLE
+    ```
+
+    Injecting your service account key:
+
+    ```sh
+    export SA_KEY_NAME=my-key-name-123
+    PORT=8080 && docker run --rm \
+        -p 8080:${PORT} -e PORT=${PORT} \
+        -e GOOGLE_APPLICATION_CREDENTIALS=/tmp/keys/${SA_KEY_NAME}.json \
+        -v $GOOGLE_APPLICATION_CREDENTIALS:/tmp/keys/${SA_KEY_NAME}.json:ro \
+        -v $PWD:/usr/src/app $SAMPLE
+    ```
+
+    Opening a shell in the container:
+
+    1. Build the container.
+
+    2. Run the container with a shell:
+
+       ```sh
+       PORT=8080 && docker run --rm \
+           --interactive --tty \
+           -p 8080:${PORT} -e PORT=${PORT} \
+           -v $PWD:/var/www/html $SAMPLE \
+           /bin/bash
+       ```
+
+    3. Exit the container: `Ctrl-D`
+

+To add composer to this example, add the following to the minimum `Dockerfile`
+included in this sample:
+
+```
+# composer prefers to use libzip and requires git for dev dependencies
+RUN apt-get update && apt-get install git libzip-dev -y
+
+# RUN docker-php-ext-configure zip --with-libzip
+RUN docker-php-ext-install zip
+
+# Install compoesr dependencies

+# Laravel on Cloud Run
+
+This sample shows you how to deploy Laravel on Cloud Run, connecting to a Cloud SQL database, and using Secret Manager for credential management.
+
+The deployed example will be a simple CRUD application listing products, and a customised Laravel welcome page showing the deployment information.
+
+![Laravel Demo Screenshot](laravel-demo-screenshot.png)
+
+
+## Objectives
+
+In this tutorial, you will:
+
+* Create and connect a Cloud SQL database.
+* Create and use Secret Manager secret values.
+* Deploy a Laravel app to Cloud Run.
+* Host static files on Cloud Storage.
+* Use Cloud Build to automate deployment.
+* Use Cloud Run Jobs to apply database migrations.
+
+## Costs
+
+This tutorial uses the following billable components of Google Cloud:
+
+* Cloud SQL
+* Cloud Storage
+* Cloud Run
+* Cloud Build
+* Artifact Registry
+* Secret Manager
+
+
+## Prerequisites
+
+* Create a [Google Cloud project](https://cloud.google.com/resource-manager/docs/creating-managing-projects)
+* Ensure [Billing](https://cloud.google.com/billing/docs/how-to/verify-billing-enabled) is enabled.
+* [Install](https://cloud.google.com/sdk/docs/install) and [initialize](https://cloud.google.com/sdk/docs/initializing) the Google Cloud CLI
+   * You can run the gcloud CLI in the Google Cloud console without installing the Google Cloud CLI. To run the gcloud CLI in the Google Cloud console, use [Cloud Shell](https://console.cloud.google.com/home/dashboard?cloudshell=true).
+* [Enable the required APIs](https://console.cloud.google.com/flows/enableapi?apiid=run.googleapis.com,sql-component.googleapis.com,sqladmin.googleapis.com,compute.googleapis.com,cloudbuild.googleapis.com,secretmanager.googleapis.com,artifactregistry.googleapis.com)
+    ```bash
+    gcloud services enable \
+        run.googleapis.com \
+        sql-component.googleapis.com \
+        sqladmin.googleapis.com \
+        compute.googleapis.com \
+        cloudbuild.googleapis.com \
+        secretmanager.googleapis.com \
+        artifactregistry.googleapis.com
+    ```
+* Ensure sufficient permissions are available to the account used for this tutorial
+   * Note: In cases where the [Owner](https://cloud.google.com/iam/docs/understanding-roles#basic) permissions role cannot be used, the following minimum roles are required to complete the tutorial: Cloud SQL Admin, Storage Admin, Cloud Run Admin, and Secret Manager Admin.
+
+## Prepare your environment
+
+* Clone a copy of the code into your local machine;
+
+    ```bash
+    git clone https://github.com/GoogleCloudPlatform/php-docs-samples.git
+    cd php-docs-samples/run/laravel/
+    ```
+
+## Confirm your PHP setup
+
+You will need PHP on your local system in order to run `php artisan` commands later.
+
+* Check you have PHP 8.1 or higher installed (or [install it](https://www.php.net/manual/en/install.php)):
+
+    ```bash
+    php --version
+    ```
+
+* Check you have `composer` installed (or [install it](https://getcomposer.org/download/)):
+
+    ```bash
+    composer --version
+    ```
+
+* Install the PHP dependencies:
+
+    ```bash
+    composer install
+    ```
+
+## Confirm your Node setup
+
+You will need Node on your local system in order to generate static assets later.
+
+* Check you have node and npm installed (or [install them](https://cloud.google.com/nodejs/docs/setup)):
+
+    ```bash
+    node --version
+    npm --version
+    ```
+
+
+* Install the Node dependencies:
+
+    ```bash
+    npm install
+    ```
+
+
+## Preparing backing services
+
+There are many variables in this tutorial. Set these early to help with copying code snippets:
+
+```
+export PROJECT_ID=$(gcloud config get-value project)
+export PROJECTNUM=$(gcloud projects describe ${PROJECT_ID} --format='value(projectNumber)')
+export REGION=us-central1
+export INSTANCE_NAME=myinstance
+export DATABASE_NAME=mydatabase
+export DATABASE_USERNAME=myuser
+export DATABASE_PASSWORD=$(cat /dev/urandom | LC_ALL=C tr -dc '[:alpha:]'| fold -w 30 | head -n1)
+export ASSET_BUCKET=${PROJECT_ID}-static
+```
+
+### Cloud SQL
+
+* Create a MySQL instance:
+
+    ```bash
+    gcloud sql instances create ${INSTANCE_NAME} \
+        --project ${PROJECT_ID} \
+        --database-version MYSQL_8_0 \
+        --tier db-f1-micro \
+        --region ${REGION}
+    ```
+
+    Note: if this operation takes longer than 10 minutes to complete, run the suggested `gcloud beta sql operations wait` command to track ongoing progress.
+
+* Create a database in that MySQL instance:
+
+    ```bash
+    gcloud sql databases create ${DATABASE_NAME} \
+        --instance ${INSTANCE_NAME}
+    ```
+
+* Create a user for the database:
+
+    ```bash
+    gcloud sql users create ${DATABASE_USERNAME} \
+        --instance ${INSTANCE_NAME} \
+        --password ${DATABASE_PASSWORD}
+    ```
+
+### Setup Cloud Storage
+
+
+* Create a Cloud Storage bucket:
+
+    ```bash
+    gsutil mb gs://${ASSET_BUCKET}
+    ```
+
+### Setup Artifact Registry
+
+* Create an Artifact Registry:
+
+    ```bash
+    gcloud artifacts repositories create containers \
+        --repository-format=docker \
+        --location=${REGION}
+    ```
+
+* Determine the registry name for future operations:
+
+    ```bash
+    export REGISTRY_NAME=${REGION}-docker.pkg.dev/${PROJECT_ID}/containers
+    ```
+
+### Configuring the Laravel Application
+
+
+* Copy the `.env.example` file into `.env`
+    ```bash
+    cp .env.example .env
+    ```
+
+* Update the values in `.env` with your values.
+
+    ⚠️ Replace `${}` with your values, don't use the literals. Get these values with e.g. `echo ${DATABASE_NAME}`
+
+    * DB_CONNECTION: `mysql`
+    * DB_SOCKET:  `/cloudsql/${PROJECT_ID}:${REGION}:${INSTANCE_NAME}`
+    * DB_DATABASE: `${DATABASE_NAME}`
+    * DB_USERNAME: `${DATABASE_USERNAME}`
+    * DB_PASSWORD: `${DATABASE_PASSWORD}`
+    * ASSET_BUCKET: `${ASSET_BUCKET}`
+
+    Note: `ASSET_URL` is generated from `ASSET_BUCKET` and doesn't need to be hardcoded.
+
+* Update the `APP_KEY` by generating a new key:
+    ```bash
+    php artisan key:generate
+    ```
+* Confirm the `APP_KEY` value in `.env` has been updated.
+
+
+### Store secret values in Secret Manager
+
+* Create a secret with the value of your `.env` file:
+
+    ```bash
+    gcloud secrets create laravel_settings --data-file .env
+    ```
+
+### Configure access to the secret
+
+* Allow Cloud Run access to the secret:
+
+    ```bash
+    gcloud secrets add-iam-policy-binding laravel_settings \
+        --member serviceAccount:${PROJECTNUM}-compute@developer.gserviceaccount.com \
+        --role roles/secretmanager.secretAccessor
+    ```
+
+## Build, Migrate, and Deploy
+
+### Build the app into a container
+
+* Using Cloud Build and Google Cloud Buildpacks, create the container image:
+
+    ```bash
+    gcloud builds submit \
+        --pack image=${REGISTRY_NAME}/laravel
+    ```
+
+### Applying database migrations
+
+With Cloud Run Jobs, you can use the same container from your service to perform administration tasks, such as database migrations.
+
+The configuration is similar to the deployment to Cloud Run, requiring the database and secret values.
+
+1. Create a Cloud Run job to apply database migrations:
+
+    ```
+    gcloud run jobs create migrate \
+        --image=${REGISTRY_NAME}/laravel \
+        --region=${REGION} \
+        --set-cloudsql-instances ${PROJECT_ID}:${REGION}:${INSTANCE_NAME} \
+        --set-secrets /config/.env=laravel_settings:latest \
+        --command launcher \
+        --args "php artisan migrate"
+    ```
+
+1. Execute the job:
+
+    ```
+    gcloud run jobs execute migrate --region ${REGION} --wait
+    ```
+
+* Confirm the application of database migrations by clicking the "See logs for this execution" link.
+
+  * You should see "INFO Running migrations." with multiple items labelled "DONE".
+  * You should also see "Container called exit(0).", where `0` is the exit code for success.
+
+### Upload static assets
+
+Using the custom `npm` command, you can use `vite` to compile and `gsutil` to copy the assets from your application to Cloud Storage.
+
+* Upload static assets:
+
+    ```bash
+    npm run update-static
+    ```
+
+    This command uses the `update-static` script in `package.json`.
+
+* Confirm the output of this operation
+
+   * You should see vite returning "N modules transformed", and gsutil returning "Operation completed over N objects"
+
+### Deploy the service to Cloud Run
+
+1. Deploy the service from the previously created image, specifying the database connection and secret configuration:
+
+    ```bash
+    gcloud run deploy laravel \
+        --image ${REGISTRY_NAME}/laravel \
+        --region $REGION \
+        --set-cloudsql-instances ${PROJECT_ID}:${REGION}:${INSTANCE_NAME} \
+        --set-secrets /config/.env=laravel_settings:latest \
+        --allow-unauthenticated
+    ```
+
+### Confirm deployment success
+
+1. Go to the Service URL to view the website.
+
+1. Confirm the information in the lower right of the Laravel welcome screen.
+
+   * You should see a variation of "Laravel v9... (PHP v8...)" (the exact version of Laravel and PHP may change)
+   * You should see the a variation of "Service: laravel. Revision laravel-00001-vid." (the revision name ends in three random characters, which will differ for every deployment)
+   * You should see "Project: (your project). Region (your region)."
+
+1. Click on the "demo products" link, and create some entries.
+
+   * You should be able to see a styled page, confirming static assets are being served.
+You should be able to write entries to the database, and read them back again, confirming database connectivity.
+
+## Updating the application
+
+While the initial provisioning and deployment steps were complex, making updates is a simpler process.
+
+To make changes: build the container (to capture any new application changes), then update the service to use this new container image:
+
+    ```bash
+    gcloud builds submit \
+        --pack image=${REGISTRY_NAME}/laravel
+    ```
+
+To apply application code changes, update the Cloud Run service with this new container:
+
+    ```bash
+    gcloud run services update laravel \
+        --image ${REGISTRY_NAME}/laravel \
+        --region ${REGION}
+    ```
+
+    Note: you do not have to re-assert the database or secret settings on future deployments, unless you want to change these values.
+
+To apply database migrations, run the Cloud Run job using the newly built container:
+
+    ```bash
+    gcloud run jobs execute migrate --region ${REGION}
+    ```
+
+    Note: To generate new migrations to apply, you will need to run `php artisan make:migration` in a local development environment.
+
+To update static assets, run the custom npm command from earlier:
+
+    ```bash
+    npm run update-static
+    ```
+
+
+## Understanding the Code
+
+### Database migrations
+
+This tutorial opts to use Cloud Run Jobs to process database applications in an environment where connections to Cloud SQL can be done in a safe and secure manner.
+
+This operation could be done on the user's local machine, which would require the installation and use of [Cloud SQL Auth Proxy](https://cloud.google.com/sql/docs/mysql/sql-proxy). Using Cloud Run Jobs removes that complexity.
+
+### Static compilation
+
+This tutorial opts to use the user's local machine for compiling and uploading static assets. While this could be done in Cloud Run Jobs, this would require building a container with both PHP and NodeJS runtimes. Because NodeJS isn't required for running the service, this isn't required to be in the container.
+
+### Secrets access
+
+`bootstrap/app.php` includes code to load the mounted secrets, if the folder has been mounted. This relates to the `--set-secrets` command used earlier.  (Look for the `cloudrun_laravel_secret_manager_mount` tag.)
+
+### Environment information
+
+`routes/web.php` includes code to retrieve the service and revision information from Cloud Run environment variable, and from the\ Cloud Run metadata service (Look for the `cloudrun_laravel_get_metadata` tag.)

+# Deploy simple nginx multi-container service NGINX/PHP-FPM
+
+A Google Cloud Project is required in order to run the sample. 
+
+## Enable required APIs
+
+The project should have the following API's enabled:
+
+* Cloud Run
+* Artifact Registry
+
+```bash
+gcloud services enable run.googleapis.com artifactregistry.googleapis.com
+```
+
+## Getting started
+
+Declare the following environment variables.
+```bash
+# References your Google Cloud Project
+export PROJECT_ID=<your-project-id>
+# References your Artifact Registry repo name
+export REPO_NAME="default"
+# References your resource location
+export REGION="us-west1"
+# References final Cloud Run multi-contaienr service name
+export MC_SERVICE_NAME="mc-php-example"
+```
+
+1. Authenticate in [gcloud cli](https://cloud.google.com/sdk/gcloud).
+
+```bash
+gcloud auth login
+```
+
+2. Create a repository within [Artifact Registry](https://cloud.google.com/artifact-registry).
+
+```bash
+gcloud artifacts repositories create ${REPO_NAME} --repository-format=docker
+```
+
+3. Build the `nginx` and `hellophp` container images for our multi-container service.
+
+```bash
+# Creating image from the Dockerfile within nginx/ dir.
+gcloud builds submit --tag=${REGION}-docker.pkg.dev/${PROJECT_ID}/${REPO_NAME}/nginx ./nginx
+
+# Creating image from the Dockerfile within php-app/ dir.
+gcloud builds submit --tag=${REGION}-docker.pkg.dev/${PROJECT_ID}/${REPO_NAME}/php ./php-app
+```
+
+4. Configure the service with the appropriate memory limit.
+
+You will see as you read through `service.yaml`, that the memory limit has been explicitly set to `335M`. This leaves ~143M for PHP processes after allocating 192M for opcache. 
+See how we got [here](https://cloud.google.com/run/docs/configuring/services/memory-limits#optimizing) and read more about how to [optimize for concurrency](https://cloud.google.com/run/docs/tips/general#optimize_concurrency).
+
+**Note:** This sample does not contain extra configuration to tune php-fpm settings to specify the number of workers to correlate with the container concurrency.
+
+5. Deploy the multi-container service.
+
+From within `service.yaml`, customize the `service.yaml` file with your own project values by replacing
+the following `PROJECT_ID`, `MC_SERVICE_NAME`, `REGION`, and `REPO_NAME`.
+
+Once you've replaced the values, you can deploy from root directory (`hello-php-nginx-sample/`).
+
+```sh
+gcloud run services replace service.yaml
+```
+
+By default, the above command will deploy the following containers into a single service:
+
+* `nginx`: `serving` ingress container (entrypoint)
+* `hellophp`: `application` container
+
+The Cloud Run Multi-container service will default access to port `8080`,
+where `nginx` container will be listening and proxy request over to `hellophp` container at port `9000`.
+
+Verify by using curl to send an authenticated request:
+
+```bash
+curl --header "Authorization: Bearer $(gcloud auth print-identity-token)" <cloud-run-mc-service-url>
+```

+# Google Secret Manager PHP Sample Application
+
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=secretmanager
+
+## Description
+
+This simple command-line application demonstrates how to invoke
+[Google Secret Manager][secretmanager] from PHP.
+
+## Build and Run
+
+1.  **Enable APIs** - [Enable the Secret Manager
+    API](https://console.cloud.google.com/flows/enableapi?apiid=secretmanager.googleapis.com)
+    and create a new project or select an existing project.
+
+1.  **Download The Credentials** - Click "Go to credentials" after enabling the
+    APIs. Click "New Credentials" and select "Service Account Key". Create a new
+    service account, use the JSON key type, and select "Create". Once
+    downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS` to
+    the path of the JSON key that was downloaded.
+
+1.  **Clone the repo** and cd into this directory
+
+    ```text
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/secretmanager
+    ```
+
+1.  **Install dependencies** via [Composer][install-composer]. If composer is
+    installed locally:
+
+
+    ```text
+    $ php composer.phar install
+    ```
+
+    If composer is installed globally:
+
+    ```text
+    $ composer install
+    ```
+
+1.  Execute the snippets in the [src/](src/) directory by running:
+
+    ```text
+    $ php src/SNIPPET_NAME.php
+    ```
+
+    The usage will print for each if no arguments are provided.
+
+See the [Secret Manager Documentation](https://cloud.google.com/secret-manager/docs) for more information.

+# Google Service Directory PHP Sample Application
+
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=servicedirectory
+
+## Description
+
+This simple command-line application demonstrates how to invoke the
+[Google Service Directory API][servicedirectory-api] from PHP.
+
+[servicedirectory-api]: https://cloud.google.com/service-directory/
+
+## Build and Run
+1.  **Enable APIs** - [Enable the Service Directory API](
+    https://console.cloud.google.com/flows/enableapi?apiid=servicedirectory.googleapis.com)
+    and create a new project or select an existing project.
+2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click
+    "New Credentials"
+    and select "Service Account Key". Create a new service account, use the JSON key type, and
+    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
+    to the path of the JSON key that was downloaded.
+3.  **Clone the repo** and cd into this directory
+```
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/servicedirectory
+```
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+5.  Execute the snippets in the [src/](src/) directory by running
+    `php src/SNIPPET_NAME.php`. The usage will print for each if no arguments
+    are provided:
+    ```sh
+    $ php src/quickstart.php
+    Usage: php src/quickstart.php PROJECT_ID STRING
+
+    $ php src/quickstart.php your-project-id us-east1
+    Namespaces: projects/you-project-id/locations/us-east1/namespaces/your-namespace
+    ```
+
+See the [Service Directory Documentation](https://cloud.google.com/service-directory/docs/) for more information.
+
+## Troubleshooting
+
+### bcmath extension missing
+
+If you see an error like this:
+
+```
+PHP Fatal error:  Uncaught Error: Call to undefined function Google\Protobuf\Internal\bccomp() in /usr/local/google/home/crwilson/github/GoogleCloudPlatform/php-docs-samples/dlp/vendor/google/protobuf/src/Google/Protobuf/Internal/Message.php:986
+```
+
+You may need to install the bcmath PHP extension.
+e.g. (may depend on your php version)
+```
+$ sudo apt-get install php8.1-bcmath
+```

 # Google Cloud Storage PHP Sample Application
 
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=storage
+
 ## Description
 
-This simple command-line application demonstrates how to invoke Google Cloud Storage from PHP.
+This simple command-line application demonstrates how to invoke
+[Google Cloud Storage][gcs-api] from PHP.
+
+[gcs-api]: https://cloud.google.com/storage/docs/reference/libraries
 
 ## Licensing
 
 * See [LICENSE](../../LICENSE)
 
-## Build and Run
-1.  **Enable APIs** - [Enable the Storage API](https://console.cloud.google.com/flows/enableapi?apiid=storage_api)
-    and create a new project or select an existing project.
-2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click "New Credentials"
-    and select "Service Account Key". Create a new service account, use the JSON key type, and
-    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
-    to the path of the JSON key that was downloaded.
-3.  **Clone the repo** and cd into this directory
-
-    ```sh
-    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
-    $ cd php-docs-samples/storage
-    ```
-4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+### Authentication
+
+Authentication is typically done through [Application Default Credentials][adc]
+which means you do not have to change the code to authenticate as long as
+your environment has credentials. You have a few options for setting up
+authentication:
+
+1. When running locally, use the [Google Cloud SDK][google-cloud-sdk]
+
+        gcloud auth application-default login
+
+1. When running on App Engine or Compute Engine, credentials are already
+   set-up. However, you may need to configure your Compute Engine instance
+   with [additional scopes][additional_scopes].
+
+1. You can create a [Service Account key file][service_account_key_file]. This file can be used to
+   authenticate to Google Cloud Platform services from any environment. To use
+   the file, set the ``GOOGLE_APPLICATION_CREDENTIALS`` environment variable to
+   the path to the key file, for example:
+
+        export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account.json
+
+[adc]: https://cloud.google.com/docs/authentication#getting_credentials_for_server-centric_flow
+[additional_scopes]: https://cloud.google.com/compute/docs/authentication#using
+[service_account_key_file]: https://developers.google.com/identity/protocols/OAuth2ServiceAccount#creatinganaccount
+
+## Install Dependencies
+
+1. [Enable the Cloud Storage API](https://console.cloud.google.com/flows/enableapi?apiid=storage.googleapis.com).
+
+1. **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
     Run `php composer.phar install` (if composer is installed locally) or `composer install`
     (if composer is installed globally).
-5.  Run `php storage.php`. The following commands are available:
-
-    ```sh
-    bucket-acl          Manage the ACL for Cloud Storage buckets.
-    bucket-default-acl  Manage the default ACL for Cloud Storage buckets.
-    bucket-labels       Manage Cloud Storage bucket labels
-    buckets             Manage Cloud Storage buckets
-    encryption          Upload and download Cloud Storage objects with encryption
-    object-acl          Manage the ACL for Cloud Storage objects
-    objects             Manage Cloud Storage objects
-    requester-pays      Manage Cloud Storage requester pays buckets and objects
-    ```
-6. Run `php storage.php COMMAND --help` to print information about the usage of each command.
+
+1. Create a service account at the
+[Service account section in the Cloud Console](https://console.cloud.google.com/iam-admin/serviceaccounts/)
+
+1. Download the json key file of the service account.
+
+1. Set `GOOGLE_APPLICATION_CREDENTIALS` environment variable pointing to that file.
+
+## Samples
+
+To run the Storage Samples, run any of the files in `src/` on the CLI:
+
+```
+$ php src/create_bucket.php
+
+Usage: create_bucket.php $bucketName
+
+  @param string $projectId The Project ID
+  @param string $bucketName The Storage bucket name
+```
+
+## Troubleshooting
+
+If you get the following error, set the environment variable `GCLOUD_PROJECT` to your project ID:
+
+```
+[Google\Cloud\Core\Exception\GoogleException]
+No project ID was provided, and we were unable to detect a default project ID.
+```
+
+## The client library
+
+This sample uses the [Cloud Storage Client Library for PHP][google-cloud-php-storage].
+You can read the documentation for more details on API usage and use GitHub
+to [browse the source][google-cloud-php-source] and  [report issues][google-cloud-php-issues].

+# Google Cloud Storage Batch Operations Samples
+
+## Description
+
+All code in the snippets directory demonstrates how to invoke
+[Cloud Storage Batch Operations][google-cloud-php-storage-batch-operations] from PHP.
+
+[cloud-storage-batch-operations]: https://cloud.google.com/storage/docs/batch-operations/overview
+
+## Setup:
+
+1.  **Enable APIs** - [Enable the Storage Batch Operations Service API](https://console.cloud.google.com/flows/enableapi?apiid=storage.googleapis.com)
+    and create a new project or select an existing project.
+2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click "New Credentials"
+    and select "Service Account Key". Create a new service account, use the JSON key type, and
+    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
+    to the path of the JSON key that was downloaded.
+3.  **Clone the repo** and cd into this directory
+
+    ```sh
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/storagebatchoperations
+    ```
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+
+
+## Samples
+
+To run the Storage Batch Operations Samples, run any of the files in `src/` on the CLI:
+
+```
+$ php src/create_job.php
+
+Usage: create_job.php $jobId $bucketName $objectPrefix
+
+  @param string $projectId The Project ID
+  @param string $jobId The new Job ID
+  @param string $bucketName The Storage bucket name
+  @param string $objectPrefix The Object prefix
+```
+
+## The client library
+
+This sample uses the [Cloud Storage Batch Operations Client Library for PHP][google-cloud-php-storage-batch-operations].
+You can read the documentation for more details on API usage and use GitHub
+to [browse the source][google-cloud-php-source] and  [report issues][google-cloud-php-issues].
+
+[google-cloud-php-storage-batch-operations]: https://cloud.google.com/php/docs/reference/cloud-storagebatchoperations/latest

+# Google Cloud Storage Control Samples
+
+## Description
+
+All code in the snippets directory demonstrate how to invoke
+[Cloud Storage Control][google-cloud-php-storage-control] from PHP.
+
+[cloud-storage-control]: https://cloud.google.com/storage/docs/access-control
+
+## Setup:
+
+1.  **Enable APIs** - [Enable the Storage Control Service API](https://console.cloud.google.com/flows/enableapi?apiid=storage.googleapis.com)
+    and create a new project or select an existing project.
+2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click "New Credentials"
+    and select "Service Account Key". Create a new service account, use the JSON key type, and
+    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
+    to the path of the JSON key that was downloaded.
+3.  **Clone the repo** and cd into this directory
+
+    ```sh
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/storagecontrol
+    ```
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+
+
+## Samples
+
+To run the Storage Control Quickstart Samples, run any of the files in `src/` on the CLI:
+
+```
+$ php src/quickstart.php
+
+Usage: quickstart.php $bucketName
+
+  @param string $bucketName The Storage bucket name
+```
+
+Above command returns the storage layout configuration for a given bucket.
+
+## The client library
+
+This sample uses the [Cloud Storage Control Client Library for PHP][google-cloud-php-storage-control].
+You can read the documentation for more details on API usage and use GitHub
+to [browse the source][google-cloud-php-source] and  [report issues][google-cloud-php-issues].

+# Google Cloud Storage Insights Samples
+
+## Description
+
+All code in the snippets directory demonstrate how to invoke
+[Cloud Storage Insights][cloud-storage-insights] from PHP.
+
+[cloud-storage-insights]: https://cloud.google.com/storage/docs/insights/inventory-reports
+
+## Setup:
+
+1.  **Enable APIs** - [Enable the Storage Insights Service API](https://console.cloud.google.com/flows/enableapi?apiid=storageinsights.googleapis.com)
+    and create a new project or select an existing project.
+2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click "New Credentials"
+    and select "Service Account Key". Create a new service account, use the JSON key type, and
+    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
+    to the path of the JSON key that was downloaded.
+3.  **Clone the repo** and cd into this directory
+
+    ```sh
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/storageinsights
+    ```
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+
+
+## Samples
+
+To run the Storage Insights Samples, run any of the files in `src/` on the CLI:
+
+```
+$ php src/create_inventory_report_config.php
+
+Usage: create_inventory_report_config.php $bucketName $sourceGcsBucketName $sinkGcsBucketName
+
+  @param string $projectId The Project ID
+  @param string $location The location of bucket
+  @param string $sourceBucketName The Storage bucket name
+  @param string $destinationBucketName The Storage bucket name
+```
+
+## The client library
+
+This sample uses the [Cloud Storage Insights Client Library for PHP][google-cloud-php-storage-insights].
+You can read the documentation for more details on API usage and use GitHub
+to [browse the source][google-cloud-php-source] and  [report issues][google-cloud-php-issues].
+
+[google-cloud-php-storage-insights]: https://cloud.google.com/storage/docs/insights/inventory-reports

+# Google Cloud Storage Transfer Samples
+
+## Description
+
+All code in the snippets directory demonstrate how to invoke
+[Cloud Storage Trasfer][cloud-storage-transfer] from PHP.
+
+`src/quickstart.php` is a sample function to create and run a transfer job between two GCS buckets.
+
+[cloud-storage-transfer]: https://cloud.google.com/storage-transfer/docs/create-transfers
+
+## Setup:
+
+1.  **Enable APIs** - [Enable the Storage Transfer Service API](https://console.cloud.google.com/flows/enableapi?apiid=storagetransfer.googleapis.com)
+    and create a new project or select an existing project.
+2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click "New Credentials"
+    and select "Service Account Key". Create a new service account, use the JSON key type, and
+    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
+    to the path of the JSON key that was downloaded.
+3.  **Clone the repo** and cd into this directory
+
+    ```sh
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/storagetransfer
+    ```
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+
+
+## Samples
+
+To run the Storage Transfer Samples, run any of the files in `src/` on the CLI:
+
+```
+$ php src/quickstart.php
+
+Usage: quickstart.php $bucketName $sourceGcsBucketName $sinkGcsBucketName
+
+  @param string $projectId The Project ID
+  @param string $sourceGcsBucketName The Storage bucket name
+  @param string $sinkGcsBucketName The Storage bucket name
+```
+
+
+## The client library
+
+This sample uses the [Cloud Storage Transfer Client Library for PHP][google-cloud-php-storage-transfer].
+You can read the documentation for more details on API usage and use GitHub
+to [browse the source][google-cloud-php-source] and  [report issues][google-cloud-php-issues].

-# Google Cloud Tasks Pull Queue Samples
+# Google Cloud Tasks Samples
 
-Sample command-line program for interacting with the Google Cloud Tasks API
-using pull queues.
+## Description
 
-Pull queues let you add tasks to a queue, then programatically remove and
-interact with them. Tasks can be added or processed in any environment,
-such as on Google App Engine or Google Compute Engine.
+All code in the snippets directory demonstrate how to invoke
+[Cloud Tasks][cloud-tasks] from PHP.
 
-`tasks.php` is a simple command-line program to demonstrate listing queues,
- creating tasks, and pulling and acknowledging tasks.
+`src/create_http_task.php` is a simple function to create tasks with an HTTP target.
 
-`src/create_task.php` is a simple function to create pull queue tasks.
-
-`src/pull_task.php` is a simple function to retrieve a pull queue task.
-
-`src/acknowledge_task.php` is a simple function to acknowledge successful
-completion of a task to remove it from the pull queue.
+[cloud-tasks]: https://cloud.google.com/tasks/docs/quickstart-appengine
 
 ## Setup:
 
@@ -34,42 +26,36 @@ completion of a task to remove it from the pull queue.
 4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
     Run `php composer.phar install` (if composer is installed locally) or `composer install`
     (if composer is installed globally).
+5.  Create a Queue
+    To create a queue using the Cloud SDK, use the following gcloud command:
+    ```sh
+    gcloud tasks queues create <QUEUE_NAME>
+    ```
 
-## Creating a queue
-
-To create a queue using the Cloud SDK, use the following gcloud command:
-
-    gcloud alpha tasks queues create-pull-queue my-pull-queue
-
-## Running the Samples
-
-Set the environment variables:
-
-Set environment variables:
-
-First, your project ID:
-
-    export PROJECT_ID=my-project-id
-
-Then the queue ID, as specified at queue creation time. Queue IDs already
-created can be listed with `gcloud alpha tasks queues list`.
-
-    export QUEUE_ID=my-pull-queue
-
-And finally the location ID, which can be discovered with
-`gcloud alpha tasks queues describe $QUEUE_ID`, with the location embedded in
-the "name" value (for instance, if the name is
-"projects/my-project/locations/us-central1/queues/my-pull-queue", then the
-location is "us-central1").
+## Using an HTTP Target
+1. Run `php src/create_http_task.php`. The usage will print for each if no arguments are provided:
 
-    export LOCATION_ID=us-central1
+    ```
+    $> php src/create_http_task.php
+    Usage: php src/create_http_task.php PROJECT_ID LOCATION_ID QUEUE_ID URL [PAYLOAD]
+    ```
 
-Create a task for a queue:
+    where:
+    * `PROJECT_ID` is your Google Cloud Project id.
+    * `QUEUE_ID` is your queue id.
+      Queue IDs already created can be listed with `gcloud tasks queues list`.
+    * `LOCATION_ID` is the location of your queue.
+      Determine the location ID, which can be discovered with
+      `gcloud tasks queues describe <QUEUE_NAME>`, with the location embedded in
+      the "name" value (for instance, if the name is
+      "projects/my-project/locations/us-central1/queues/my-queue", then the
+      location is "us-central1").
+    * `URL` is the full URL to your target endpoint.

+# Cloud Text-to-Speech: PHP Samples
+
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=texttospeech
+
+## Description
+
+These command-line samples demonstrates how to invoke
+[Cloud Text-to-Speech API][tts-api] from PHP.
+
+[tts-api]: https://cloud.google.com/text-to-speech/docs/quickstart-client-libraries
+
+## Setup
+
+### Authentication
+
+This sample requires you to have authentication setup. Refer to the [Authentication Getting Started Guide](https://cloud.google.com/docs/authentication/getting-started) for instructions on setting up credentials for applications.
+
+## Install Dependencies
+
+1. [Enable the Cloud Text-to-Speech API](https://console.cloud.google.com/flows/enableapi?apiid=texttospeech.googleapis.com).
+
+1. **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `composer install` (if composer is installed globally).
+
+## Samples
+
+### List voices
+
+Run `php src/SNIPPET_NAME.php`. The usage will print for each if arguments are required:
+
+```sh
+$ php src/synthesize_text.php
+Usage: php src/synthesize_text.php TEXT
+
+$ php src/list_voices.php
+Name: ar-XA-Wavenet-A
+Supported language: ar-XA
+SSML voice gender: FEMALE
+Natural Sample Rate Hertz: 24000
+...
+```
+
+### Synthesize text/ssml
+
+```
+Usage:
+  php src/synthesize_text.php <TEXT>
+  php src/synthesize_ssml.php <SSML>
+
+Examples:
+  php src/synthesize_text_audio_profile.php
+  php src/synthesize_text.php "Hello there."
+  php src/synthesize_ssml.php "<speak>Hello there.</speak>"
+  php src/synthesize_text_effects_profile.php "Hello there." "handset-class-device"
+```
+
+### Synthesize file
+```
+Usage:
+  php src/synthesize_text_file.php <FILE_PATH>
+  php src/synthesize_ssml_file.php <FILE_PATH>
+  php src/synthesize_text_effects_profile_file.php <FILE_PATH> <AUDIO_PROFILE>
+
+Examples:
+  php src/synthesize_text_file.php
+  php texttospeech.php synthesize_ssml_file.php
+  php src/synthesize_text_audio_profile_file.php
+  php src/synthesize_text_file.php resources/hello.txt
+  php src/synthesize_ssml_file.php resources/hello.ssml
+  php src/synthesize_text_effects_profile_file.php resources/hello.txt "handset-class-device"
+```
+
+## The client library
+
+This sample uses the [Cloud Text To Speech Client Library for PHP][google-cloud-php-tts].
+You can read the documentation for more details on API usage and use GitHub
+to [browse the source][google-cloud-php-source] and [report issues][google-cloud-php-issues].
+
+## Troubleshooting
+
+If you get the following error, set the environment variable `GCLOUD_PROJECT` to your project ID:
+
+```
+[Google\Cloud\Core\Exception\GoogleException]
+No project ID was provided, and we were unable to detect a default project ID.
+```
+
+If you have not set a timezone you may get an error from php. This can be resolved by:
+
+  1. Finding where the php.ini is stored by running `php -i | grep 'Configuration File'`
+  1. Finding out your timezone from the list on this page: http://php.net/manual/en/timezones.php
+  1. Editing the php.ini file (or creating one if it doesn't exist)
+  1. Adding the timezone to the php.ini file e.g., adding the following line: `date.timezone = "America/Los_Angeles"`

     Run `php composer.phar install` (if composer is installed locally) or `composer install`
     (if composer is installed globally).
 5.  For a basic demonstration of the Cloud Vision API, run `php quickstart.php`.
-6.  Run `php vision.php`. The following commands are available:
+6.  Execute the snippets in the [src/](src/) directory by running
+    `php src/SNIPPET_NAME.php`. The usage will print for each if no arguments

-7. Run `php vision.php COMMAND --help` to print information about the usage of each command.
+
+If you have not set a timezone you may get an error from php. This can be resolved by:
+
+  1. Finding where the php.ini is stored by running `php -i | grep 'Configuration File'`
+  1. Finding out your timezone from the list on this page: http://php.net/manual/en/timezones.php
+  1. Editing the php.ini file (or creating one if it doesn't exist)
+  1. Adding the timezone to the php.ini file e.g., adding the following line: `date.timezone = "America/Los_Angeles"`
