Background Worker Manager

If you ever want to run something in the background(i.e. a callable that is often referred to as worker), you should have a look at BackgroundWorkerManager class. This class provides the following features:

• Run multiple workers in the background (forked process)
• An ordered worker queue which limits the concurrent running worker to a preset number
• Wait functionality for the parent process

Example:

<?php

$man = new BackgroundWorkerManager(2);
$man->addWorker(
    function (WorkerInfo $info) {
        echo sprintf(
            "This is the #%d worker executed out of a total of %d",
            $info->currentWorkerIndex,
            $info->totalWorkers
            );
    },
    10
    ); // add 10 workers to the manager

$man->run(); // all workers will be executed in order, no more than 2 workes will be running at the same time

$man->wait();
