 # Swoole
 
-?> `Swoole` is a parallel network communication engine based on asynchronous event-driven and coroutine, written in `C++`, providing [coroutine](/coroutine) and [high-performance](/question/use?id=swoole performance how) network programming support for `PHP`. It provides various network server and client modules for multiple communication protocols, making it easy to quickly implement `TCP/UDP services`, `high-performance Web`, `WebSocket services`, `IoT`, `real-time communication`, `games`, `microservices`, etc., breaking the limits of `PHP` in traditional web domains.
