PHP を使用して WeChat アプレットのリアルタイム チャット機能を実装するにはどうすればよいですか?

require 'vendor/autoload.php';
use RatchetMessageComponentInterface;
use RatchetConnectionInterface;

class ChatServer implements MessageComponentInterface {
   protected $clients;

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

   public function onOpen(ConnectionInterface $conn) {
      $this->clients->attach($conn);
   }

   public function onMessage(ConnectionInterface $from, $msg) {
      // 处理客户端发送的消息
      $data = json_decode($msg, true);
      // 将消息发送给所有连接的客户端
      foreach ($this->clients as $client) {
         $client->send(json_encode($data));
      }
   }

   public function onClose(ConnectionInterface $conn) {
      $this->clients->detach($conn);
   }

   public function onError(ConnectionInterface $conn, Exception $e) {
      $conn->close();
   }
}

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

const socket = wx.connectSocket({
   url: 'ws://localhost:8080',
   success: function() {
      console.log('WebSocket连接成功');
   }
});

socket.onOpen(function() {
   console.log('WebSocket连接已打开');
   // 发送消息
   socket.send({
      message: 'Hello, WebSocket!'
   });
});

socket.onMessage(function(res) {
   console.log('收到消息：', res.data);
   // 处理收到的消息
});

socket.onClose(function() {
   console.log('WebSocket连接已关闭');
});
