    One shall note, that callback function MUST either return a valid Gearman status code, or return nothing (do not return).

    I.e. these are valid complete callbacks:

    <?php
    function goodCallbackOne(GearmanTask $task)
    {
            print_r($task);
    }
    ?>

    <?php
    function goodCallbackTwo(GearmanTask $task)
    {
            print_r($task);
        return     GEARMAN_SUCCESS;
    }
    ?>

    While following is NOT, unless you want your client code to fail with Gearman error 'german wait:no active file descriptors':

    <?php
    function badCallbackTwo(GearmanTask $task)
    {
            print_r($task);
        return     true;
    }
    ?>
