    GearmanClient::setWorkloadCallback — Set a callback for accepting incremental data updates

    説明

    public GearmanClient::setWorkloadCallback(callable $callback): bool

    Sets a callback function to be called when a worker needs to send back data prior to job completion. A worker can do this when it needs to send updates, send partial results, or flush data during long running jobs.

    注意:

    The callback will only be triggered for tasks that are added (e.g. by calling GearmanClient::addTask()) after calling this method.
