Swow is a coroutine-based concurrent I/O engine for PHP, implemented as a C extension with most functionality exposed through PHP code. It enables high-performance asynchronous network programming on Linux, Windows, and macOS with PHP 8+.
Use cases
- build high-performance async PHP servers
- write coroutine-based concurrent I/O in PHP
- run non-blocking HTTP or WebSocket servers in PHP
- replace Swoole with a modern coroutine engine
- handle thousands of concurrent connections in PHP
When to choose
- you need coroutine-based async I/O in PHP 8+
- you want cross-platform support including Windows
- you value debuggability and a small C core with PHP-level extensibility
When to avoid
- you are on PHP below 8.0
- you need a batteries-included framework rather than an engine
- your project is simple synchronous web development where coroutines add complexity
