int Worker::$count

Set how many processes the current Worker instance will start. When not set, the default value is 1.

For instructions on how to set the number of processes, please refer to here.

Note: This property must be set before Worker::runAll(); is called in order to take effect. This feature is not supported on Windows systems.

$worker->count = 8;
$worker->onWorkerStart = function($worker)
    echo "Worker starting...\n";
// Run worker
