workerman使用教程（以WebSocket为例）

创建workerman.websocket.php文件，代码如下：

<?php
// +-----------------------------------------------------------------------------------------+ //
// | 使用WebSocket协议对外提供服务                                                           | //
// | 启动方式：/program/php/bin/php /inetpub/wwwroot/workerman/workerman.websocket.php start | //
// +-----------------------------------------------------------------------------------------+ //

use Workerman\Worker;
use Workerman\Connection\TcpConnection;

require_once __DIR__ . '/workerman/vendor/autoload.php';

$worker = new Worker('websocket://0.0.0.0:2000');

$worker->count = 4; // 启动4个进程对外提供服务

// 接收到客户端发送过来的消息的回调函数
$worker->onMessage = static function (TcpConnection $connection, $data) {
    $connection->send("{$data}，人生无处不青山。"); // 向客户端发送消息
};

Worker::runAll(); // 运行worker

启动服务器

[root@localhost ~]# /program/php/bin/php /inetpub/wwwroot/workerman/workerman.websocket.php start

Workerman[/inetpub/wwwroot/workerman/workerman.websocket.php] start in DEBUG mode

------------------------------------------- WORKERMAN --------------------------------------------

Workerman version:4.1.4 PHP version:8.1.7 Event-Loop:\Workerman\Events\Select

-------------------------------------------- WORKERS ---------------------------------------------

proto user worker listen processes status

tcp root none websocket://0.0.0.0:2000 4 [OK]

--------------------------------------------------------------------------------------------------

Press Ctrl+C to stop. Start success. # 按Ctrl+C可停止服务器

^CWorkerman[workerman.websocket.php] stopping ...

Workerman[workerman.websocket.php] has been stopped
