php怎么向websocket服务端发送信息啊

composer require cboden/ratchetCopy

<?php

require __DIR__.'/vendor/autoload.php';

use Ratchet\Client\WebSocket;

// 要连接的 WebSocket URL
$wsUrl = 'wss://your-websocket-url.com';

// 创建 WebSocket 客户端实例
$wsClient = new WebSocket($wsUrl);

// 连接事件处理
$wsClient->on('connect', function ($conn) {
    echo "已连接到 WebSocket 服务器\n";

    // 向服务器发送一条消息
    $conn->send('你好，服务器！');
});

// 消息事件处理
$wsClient->on('message', function ($msg) {
    echo "收到消息：$msg\n";
});

// 错误事件处理
$wsClient->on('error', function ($e) {
    echo "发生错误：{$e->getMessage()}\n";
});

// 关闭事件处理
$wsClient->on('close', function ($code = null, $reason = null) {
    echo "连接已关闭\n";
});

// 连接到 WebSocket 服务器
$wsClient->connect();
Copy

$client = stream_socket_client(ws服务地址);
if (!$client) {
    return;
}
$data = [ ... ];
fwrite($client, json_encode($cmd) . "\n");
fclose($client);Copy
