ReactPHP is a low-level PHP library for event-driven, non-blocking I/O built around a core event loop (reactor pattern). It provides reusable components including streams, async DNS resolution, TCP/UDP sockets, HTTP client/server, promises, and process interaction for building concurrent network applications.

Use cases

• build an async http server in php without a web server
• handle thousands of concurrent tcp connections in php
• make concurrent non-blocking http requests from php
• run long-running php processes with an event loop
• stream large files without loading them into memory
• write async php code with promises and fibers
• build a udp datagram client or server in php

When to choose

• you need high-concurrency network servers or clients in PHP
• you want non-blocking I/O for long-running PHP applications
• you need streaming processing of large data in small chunks
• you want a Node.js-style async programming model in PHP

When to avoid

• your app is a typical short-lived request/response PHP web app under Apache/nginx
• you need to run blocking legacy libraries that can't be made async
• your team is unfamiliar with event-driven programming and deadlines are tight
