    if (    $frame['body'] === $msg) {

    stomp_ack($link, $frame['headers']['message-id']);
    }


    stomp_unsubscribe($link, $queue);


    stomp_close($link);

    ?>

    Notlar

    Bilginize:

    A transaction header may be specified, indicating that the message acknowledgment should be part of the named transaction.

    İpucu

    Stomp is inherently asynchronous. Synchronous communication can be implemented adding a receipt header. This will cause methods to not return anything until the server has acknowledged receipt of the message or until read timeout was reached.
