## What it is
Swoole is an event-driven, asynchronous, coroutine-based concurrency library implemented as a PHP extension in C++. It enables PHP to run high-performance TCP/UDP/HTTP/WebSocket servers and concurrent I/O without external web servers.

## Use cases
- build high-concurrency websocket servers in php
- run async coroutines in php
- serve http without nginx php-fpm
- write tcp/udp socket servers in php
- make concurrent http requests in php
- build realtime applications with php

## When to choose
- you need high-throughput, long-running PHP services like websocket or game servers
- you want coroutine-based async I/O in PHP without rewriting in another language

## When to avoid
- you run simple shared-hosting or short-lived PHP scripts
- you depend on extensions/libraries incompatible with Zend extension hooks or long-running processes

## Facets
- artifact type: library
- maturity: active
- function: concurrency, http-server, websocket, networking
- domain: web-development, backend, networking
- platform: windows, php
- tags: coroutines, event-driven, php-extension, high-performance, async-io, real-time, linux, macos, docker
