    If you suddenly start getting a:

    PHP Fatal error: Uncaught exception 'GearmanException' with message 'Failed to set exception option' in

    ...on your GearmanWorker::work() calls, I was able to fix this by specifying values to GearmanWorker::addServer(), even if they are the same as the documented default values.

    Crashes:

    <?php
    $gmw     = new GearmanWorker();
    $gmw->addServer();
    $gmw->work();
    ?>

    Works:

    <?php
    $gmw     = new GearmanWorker();
    $gmw->addServer("127.0.0.1", 4730);
    $gmw->work();
    ?>

    Go figure. :)

    To properly test the server added you could use the following code:

    <?php
    // create the worker
    $worker= new GearmanWorker();

    // add the job server (bad host/port)
    $worker->addServer('127.0.0.2', 4731);

    // define a variable to hold application data
    $count = 0;

    // add the reverse function
    $worker->addFunction('reverse', 'my_reverse_function', $count);

    // test job server response
    if (!@$worker->echo('test data')) {
    die(    $worker->error());
    }

    // start the worker listening for job submissions
    while ($worker->work());

    function     my_reverse_function($job, &$count)
    {
    $count++;

    return     $count . ': ' . strrev($job->workload()) . "\n";
    }
    ?>

    The manual states that you get a TRUE on success and FALSE on failure. When I have attempted to connect to a server that is powered off I still get TRUE. The return from returnCode() is 0 which is the same as the returnCode() from a successful connection.

    I have not yet found a way around this.
