请教一个UDP接收数据并显示的问题

<?php
  require_once __DIR__ . '/../Workerman/Autoloader.php';
  use Workerman\Worker;
  $ws_worker = new Worker('websocket://0.0.0.0:1234');
  $ws_worker->onWorkerStart = function($ws_worker) {
      $udp_worker = new Worker('udp://0.0.0.0:5678');
      $udp_worker->onMessage = function($udp_connection, $data)use($ws_worker) {
          foreach($ws_worker->connections as $ws_connection) {
              $ws_connection->send($data);
          }
      };
      $udp_worker->listen();
  };

  $http_worker = new Worker('http://0.0.0.0:8080');
  $http_worker->onMessage = function($http_connection, $http_data) {
      $http_connection->send('
  <script>
      var ws = new WebSocket("ws://127.0.0.1:1234");
      ws.onmessage = function(e){
          alert(e.data)
      };
  </script>');
  };
  Worker::runAll();

浏览器访问8080端口，
udp数据发送到5678端口，数据会在8080端口的网页上弹出来。
