PHP 实现 WebSocket

使用 `Ratchet` 库

Ratchet 是一个流行的 PHP WebSocket 库，基于 ReactPHP 实现，适合构建实时应用。

安装 Ratchet：

composer require cboden/ratchet

创建 WebSocket 服务器：

<?php
use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use MyApp\Chat;

require dirname(__DIR__) . '/vendor/autoload.php';

class Chat implements \Ratchet\MessageComponentInterface {
    protected $clients;

    public function __construct() {
        $this->clients = new \SplObjectStorage;
    }

    public function onOpen(\Ratchet\ConnectionInterface $conn) {
        $this->clients->attach($conn);
        echo "New connection: {$conn->resourceId}\n";
    }

    public function onMessage(\Ratchet\ConnectionInterface $from, $msg) {
        foreach ($this->clients as $client) {
            if ($from !== $client) {
                $client->send($msg);
            }
        }
    }

    public function onClose(\Ratchet\ConnectionInterface $conn) {
        $this->clients->detach($conn);
        echo "Connection closed: {$conn->resourceId}\n";
    }

    public function onError(\Ratchet\ConnectionInterface $conn, \Exception $e) {
        echo "Error: {$e->getMessage()}\n";
        $conn->close();
    }
}

$server = IoServer::factory(
    new HttpServer(new WsServer(new Chat())),
    8080
);
$server->run();

运行服务器：

php server.php

使用 `Swoole` 扩展

Swoole 是一个高性能 PHP 协程框架，内置 WebSocket 支持。

安装 Swoole：

pecl install swoole

创建 WebSocket 服务器：

<?php
$server = new Swoole\WebSocket\Server("0.0.0.0", 9501);

$server->on('open', function (Swoole\WebSocket\Server $server, $request) {
    echo "Connection open: {$request->fd}\n";
});

$server->on('message', function (Swoole\WebSocket\Server $server, $frame) {
    foreach ($server->connections as $fd) {
        if ($fd !== $frame->fd) {
            $server->push($fd, $frame->data);
        }
    }
});

$server->on('close', function ($server, $fd) {
    echo "Connection closed: {$fd}\n";
});

$server->start();

运行服务器：

php server.php

客户端连接示例

使用 JavaScript 连接 WebSocket 服务器：

php实现websochet

const socket = new WebSocket('ws://localhost:8080');

socket.onopen = function(e) {
    console.log('Connected to server');
    socket.send('Hello Server!');
};

socket.onmessage = function(event) {
    console.log('Message from server:', event.data);
};

socket.onclose = function(event) {
    console.log('Connection closed');
};
