Getting Started with ReactPHP

ReactPHP logo

ReactPHP is a powerful library for event-driven, non-blocking I/O with PHP, allowing for the creation of high-performance, scalable applications. It provides a toolkit for handling asynchronous operations using an event loop and promises.

ReactPHP is separated into different packages to maintain modularity and flexibility. This design allows developers to include only the components they need, leading to leaner and more efficient applications.
