要處理PHP STOMP消息，您需要遵循以下步驟：

  1. 安裝STOMP庫：首先，確保您的PHP環(huán)境中已安裝stomp.php庫。您可以使用Composer進(jìn)行安裝：
composer require cboden/ratchet
  1. 創(chuàng)建一個WebSocket服務(wù)器：接下來，創(chuàng)建一個WebSocket服務(wù)器以便與STOMP客戶端通信。這里是一個簡單的例子：
// server.php
require 'vendor/autoload.php';

use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use MyApp\StompHandler;

$server = IoServer::factory(
    new HttpServer(
        new WsServer(
            new StompHandler()
        )
    ),
    8080
);

$server->run();
  1. 創(chuàng)建一個STOMP處理器：現(xiàn)在，我們需要創(chuàng)建一個處理器來處理傳入的STOMP消息。在這個例子中，我們將簡單地將接收到的消息原樣返回：
// MyApp/StompHandler.php
namespace MyApp;

use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
use Stomp\Client as StompClient;

class StompHandler implements MessageComponentInterface {
    protected $clients;

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

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

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

    public function onError(ConnectionInterface $conn, \Exception $e) {
        echo "An error has occurred: {$e->getMessage()}\n";
        $conn->close();
    }

    public function onMessage(ConnectionInterface $from, $msg) {
        foreach ($this->clients as $client) {
            if ($from !== $client) {
                $client->send($msg);
            }
        }
    }
}
  1. 運(yùn)行WebSocket服務(wù)器：最后，運(yùn)行WebSocket服務(wù)器以偵聽傳入的STOMP連接：
php server.php

現(xiàn)在，您可以使用STOMP客戶端連接到WebSocket服務(wù)器并發(fā)送/接收消息。這是一個簡單的STOMP客戶端示例：

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

use Stomp\Client;

$client = new Client('ws://localhost:8080');

$client->connect();

$client->subscribe('/topic/my_topic', function ($message) {
    echo "Received message: {$message->body}\n";
});

$client->send('/topic/my_topic', '', 'Hello, World!');

sleep(10);

$client->disconnect();

運(yùn)行此客戶端以發(fā)送消息到STOMP服務(wù)器，服務(wù)器將把消息廣播給所有訂閱了該主題的其他客戶端。
