Beispiel #1 Objektorientierter Stil

    <?php

    $queue  = '/queue/foo';
    $msg    = 'bar';

    /* connection */
    try {
        $stomp = new Stomp('tcp://localhost:61613');
    } catch(StompException $e) {
        die('Connection failed: ' . $e->getMessage());
    }

    /* send a message to the queue 'foo' */
    $stomp->send($queue, $msg);

    /* subscribe to messages from the queue 'foo' */
    $stomp->subscribe($queue);

    /* read a frame */
    $frame = $stomp->readFrame();

    if ($frame->body === $msg) {
        var_dump($frame);

        /* acknowledge that the frame was received */
        $stomp->ack($frame);
    }

    /* close connection */
    unset($stomp);

    ?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    object(StompFrame)#2 (3) {
      ["command"]=>
      string(7) "MESSAGE"
      ["headers"]=>
      array(5) {
        ["message-id"]=>
        string(41) "ID:php.net-55293-1257226743606-4:2:-1:1:1"
        ["destination"]=>
        string(10) "/queue/foo"
        ["timestamp"]=>
        string(13) "1257226805828"
        ["expires"]=>
        string(1) "0"
        ["priority"]=>
        string(1) "0"
      }
      ["body"]=>
      string(3) "bar"
    }

Beispiel #2 Prozeduraler Stil

    <?php

    $queue  = '/queue/foo';
    $msg    = 'bar';

    /* connection */
    $link = stomp_connect('ssl://localhost:61612');

    /* check connection */
    if (!$link) {
        die('Connection failed: ' . stomp_connect_error());
    }

    /* begin a transaction */
    stomp_begin($link, 't1');

    /* send a message to the queue 'foo' */
    stomp_send($link, $queue, $msg, array('transaction' => 't1'));

    /* commit a transaction */
    stomp_commit($link, 't1');

    /* subscribe to messages from the queue 'foo' */
    stomp_subscribe($link, $queue);

    /* read a frame */
    $frame = stomp_read_frame($link);

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

        /* acknowledge that the frame was received */
        stomp_ack($link, $frame['headers']['message-id']);
    }

    /* close connection */
    stomp_close($link);

    ?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    array(3) {
      ["command"]=>
      string(7) "MESSAGE"
      ["body"]=>
      string(3) "bar"
      ["headers"]=>
