Workerman开发实战：搭建高效的即时通讯系统

<?php
require_once __DIR__.'/vendor/autoload.php';

use WorkermanWorker;

// 创建一个Worker监听2345端口，使用websocket协议通信
$ws_worker = new Worker("websocket://0.0.0.0:2345");

// 设置进程数
$ws_worker->count = 4;

// 当客户端连接时
$ws_worker->onConnect = function($connection){
    echo "New connection
";
};

// 当客户端发送消息时
$ws_worker->onMessage = function($connection, $data){
    foreach($connection->worker->connections as $clientConnection){
        $clientConnection->send($data);
    }
};

// 当客户端断开连接时
$ws_worker->onClose = function($connection){
    echo "Connection closed
";
};

// 运行worker
Worker::runAll();

<?php
require_once __DIR__.'/vendor/autoload.php';

use WorkermanWorker;
use WorkermanAutoloader;
use WorkermanConnectionAsyncTcpConnection;

$connect_list = array();

// 当用户输入消息时
function onMessage($connect)
{
    // 从终端读取用户输入的消息
    $message = trim(fgets(STDIN));
    
    // 发送消息到服务端
    $connect->send($message);
}

// 创建一个异步TCP连接到服务端
$connect = new AsyncTcpConnection('ws://127.0.0.1:2345');
$connect->onConnect = function($connection){
    echo "Connected to server
";
};
$connect->onMessage = function($connection, $data){
    echo "Received message: ".$data."
";
};
$connect->onClose = function($connection){
    echo "Disconnected from server
";
};

// 运行连接
$connect->connect();

// 将连接对象保存到连接列表中
$connect_list[] = $connect;

// 监听用户输入消息
Worker::addWorker(function(){
    readline_callback_handler_install('', function(){});
    while (true) {
        if (count($GLOBALS['connect_list']) > 0) {
            $read = array_values($GLOBALS['connect_list']);
            $write = null;

            if (false === ($num_changed_streams = stream_select($read, $write, $except, 1))) {
