Swoole: Redefines PHP

PHP's asynchronous, parallel, high-performance network communication engine, written in pure C language, provides an asynchronous multi-threaded server in PHP language, asynchronous TCP/UDP network client, asynchronous MySQL, asynchronous Redis, database connection pool, AsyncTask, message queue, millisecond timer, asynchronous file reading and writing, asynchronous DNS query. Swoole has built-in Http/WebSocket server/client and Http2.0 server.
Swoole can be widely used in the Internet, mobile communications, enterprise software, cloud computing, online games, Internet of Things, Internet of Vehicles, smart homes and other fields. Using PHP+Swoole as the network communication framework can greatly improve the efficiency of the enterprise IT R&D team and focus more on developing innovative products.
