### Examples

Example #1 Object-oriented style

    <?php

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

    var_dump($stomp->error());

    if (!$stomp->abort('unknown-transaction', array('receipt' => 'foo'))) {
        var_dump($stomp->error());
    }

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

    ?>

The above example will output something similar to:

    bool(false)
    string(43) "Invalid transaction id: unknown-transaction"

Example #2 Procedural style

    <?php

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

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

    var_dump(stomp_error($link));

    if (!stomp_abort($link, 'unknown-transaction', array('receipt' => 'foo'))) {
        var_dump(stomp_error($link));
    }

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

    ?>

The above example will output something similar to:

    bool(false)
    string(43) "Invalid transaction id: unknown-transaction"
