如何实现PHP表单提交后的数据推送和订阅

use RatchetMessageComponentInterface;
use RatchetConnectionInterface;

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

class PushServer implements MessageComponentInterface
{
    protected $clients;

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

    public function onOpen(ConnectionInterface $conn)
    {
        echo "新连接（{$conn->resourceId}）加入
";
        $this->clients->attach($conn);
    }

    public function onMessage(ConnectionInterface $from, $msg)
    {
        echo "收到来自（{$from->resourceId}）的消息：{$msg}
";
        foreach ($this->clients as $client) {
            $client->send($msg);
        }
    }

    public function onClose(ConnectionInterface $conn)
    {
        echo "连接（{$conn->resourceId}）关闭
";
        $this->clients->detach($conn);
    }

    public function onError(ConnectionInterface $conn, Exception $e)
    {
        echo "出现错误：{$e->getMessage()}
";
        $conn->close();
    }
}

$server = RatchetServerIoServer::factory(
    new RatchetHttpHttpServer(
        new RatchetWebSocketWsServer(
            new PushServer()
        )
    ),
    8080
);

$server->run();

<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // 处理表单提交的数据
    $data = $_POST['data'];

    // 将数据发送给WebSocket服务器
    $client = new RatchetClientWebSocket('ws://localhost:8080');
    $client->send($data);
    $client->close();
}
?>
