Instead of passing localhost to mysqli_connect as the $host parameter
I think it'd be useful if you could pass something like
ssh2.tunnel://user:[email protected]:22/192.168.0.1:14 to it as well.

The main advantage I see of doing that is that you could tunnel
through SSH2, through SOCKS, through HTTP CONNECT, etc, a lot more
easily than you currently can. Like you could have an SSH connection
re-created every time a PHP script is called and a tunnel dynamically
made instead of having a persistent tunnel created with autossh or
whatever.

And even if SSH2 / SOCKS / CONNECT don't exist as built-in wrappers
custom stream wrappers could be made. This would additionally make it
easy for people to examine the underpinnings of MySQL. Instead of
intercepting the packets the MySQL client sends out and placing them
into an SSH tunnel or whatever one could just dump them to a log file
to better understand how MySQL clients work internally.


Instead of adding all that gear to PHP itself, wouldn't it make more
sense to just use something like autossh to maintain your ssh tunnel and
have PHP connect to your tunnel endpoint? mysqli_connect() in PHP is
just a thin wrapper on top of the underlying library.


Oh - I didn't know that. I thought (hoped) it might have been like a
two second code change lol.



a very easy way is to write a mysqlnd plugin that overwrites mysqlnd_connect, maybe some small changes to mysqlnd_net. You can pass whatever you want and it will connect the way you want. At the end there should be opened PHP stream. Upload it to pecl.php.net and let the people use it. If many people decide to use it it might get its way into the core of mysqlnd.

Best,
Andrey
