Swoole: Redefining PHP

PHP’s asynchronous, parallel, high-performance network communication engine, written in pure C language, provides 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 a network communication framework can greatly improve the efficiency of enterprise IT R&D teams and focus more on developing innovative products.

Simple case:

</span><span>//</span><span> 启动服务器</span>
<span>$server</span> = <span>new</span> Server();

<?<span>php

}

</span><span>$client</span> = <span>new</span><span> Client();
</span><span>$client</span>->connect();

Open two terminals respectively and enter: php server.php | php client.php to see the effect!
