workermanWhat is it?
Workerman is an asynchronous event-driven PHP framework with high performance, making it easy to build fast, scalable web applications. Supports HTTP, Websocket, SSL and other custom protocols. Support libevent, HHVM, ReactPHP.
Recommended: "workerman Tutorial"
Requirements
PHP 5.3或更高版本 兼容POSIX的操作系统（Linux，OSX，BSD） 用于PHP的POSIX和PCNTL扩展
Installation
composer require workerman/workerman
Basic usage
websocket server
<?php
require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
// 创建一个Websocket服务器
$ws_worker = new Worker("websocket://0.0.0.0:2346");

// 在新连接到来时发出
$ws_worker->onConnect = function($connection)
{
echo "New connection\n";
};
// 接收数据时发出
$ws_worker->onMessage = function($connection, $data)
{
// Send hello $data
$connection->send('hello ' . $data);
};
// 连接关闭时发出
$ws_worker->onClose = function($connection)
{

};
// 运行worker

//$_GET、$_POST、$_COOKIE、$_SESSION、$_SERVER、$_FILES都是可用的
var_dump($_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES);
// 发送数据给客户端

// 运行所有workers
Worker::runAll();WebServer

// 创建一个带有ssl的Websocket服务器。
$ws_worker = new Worker("websocket://0.0.0.0:2346", $context);
// 启用SSL。WebSocket+SSL意味着安全的WebSocket (wss://)。
//类似的Https方法等等。
