    Örnekler

    Örnek 1 Submit and monitor a background job

    The worker in this example has an artificial delay introduced to mimic a long running job. The client script periodically checks the status of the running job.

    <?php


    $gmclient= new GearmanClient();


    $gmclient->addServer();


    $job_handle = $gmclient->doBackground("reverse", "this is a test");

    if (    $gmclient->returnCode() != GEARMAN_SUCCESS)
    {
    echo     "bad return code\n";
    exit;
    }

    $done = false;
    do
    {
    sleep(3);
    $stat = $gmclient->jobStatus($job_handle);
    if (!    $stat[0]) // the job is known so it is not done
    $done = true;
    echo     "Running: " . ($stat[1] ? "true" : "false") . ", numerator: " . $stat[2] . ", denominator: " . $stat[3] . "\n";
    }
    while(!    $done);

    echo     "done!\n";

    ?>

    Yukarıdaki örnek şuna benzer bir çıktı üretir:

    Running: true, numerator: 3, denominator: 14 Running: true, numerator: 6, denominator: 14 Running: true, numerator: 9, denominator: 14 Running: true, numerator: 12, denominator: 14 Running: false, numerator: 0, denominator: 0 done!
