    GearmanClient::addTaskHigh — Add a high priority task to run in parallel

    Açıklama

    public GearmanClient::addTaskHigh(
        string $function_name,
        string|int|float $workload,
        mixed $context = null,
        ?string $unique_key = null
    ): GearmanTask|false

    Adds a high priority task to be run in parallel with other tasks. Call this method for all the high priority tasks to be run in parallel, then call GearmanClient::runTasks() to perform the work. Tasks with a high priority will be selected from the queue before those of normal or low priority.

    Örnekler

    Örnek 1 A high priority task along with two normal tasks

    A high priority task is included among two other tasks. A single worker is available, so that tasks are run one at a time, with the high priority task run first.

    <?php

    # create the gearman client
    $gmc= new GearmanClient();

    # add the default job server
    $gmc->addServer();

    # set the callback for when the job is complete
    $gmc->setCompleteCallback("reverse_complete");

    # add tasks, one of which is high priority
    $task= $gmc->addTask("reverse", "Hello World!", null, "1");
    $task= $gmc->addTaskHigh("reverse", "!dlroW olleH", null, "2");
    $task= $gmc->addTask("reverse", "Hello World!", null, "3");

    if (!     $gmc->runTasks())
    {
    echo     "ERROR " . $gmc->error() . "\n";
    exit;
    }
    echo     "DONE\n";

    function     reverse_complete($task)
    {
    echo     "COMPLETE: " . $task->unique() . ", " . $task->data() . "\n";
    }

    ?>

    Yukarıdaki örnek şuna benzer bir çıktı üretir:

    COMPLETE: 2, Hello World!
COMPLETE: 3, !dlroW olleH
COMPLETE: 1, !dlroW olleH
DONE
