Build fast, concurrent applications with PHP

Benefit from concurrency by replacing your blocking I/O with non-blocking I/O,
or designing your system with non-blocking I/O from the ground up.

We shipped fibers in PHP 8.1 to extend its capabilities for concurrent applications.

The PHP standard library has already provided everything else we needed for years now, but it only ships the low-level building blocks. AMPHP provides higher-level libraries using non-blocking I/O under the hood. Fibers allow these libraries to just work, no matter whether they're used in concurrent or traditional contexts.
