PHP Class to handle concurrent running Jobs to utilize the power of multiple cores

After some search I was not able to find a php-queue alike class. This code was inspired by php-resque

• PHP 5.3+
• php-pctnl
• Composer

The easiest way to work with php-queue is when it's installed as a Composer package inside your project. Composer isn't strictly required, but makes life a lot easier.

If you're not familiar with Composer, please see http://getcomposer.org/.

1. Add php-queue to your application's composer.json.

{
    // ...
    "require": {
        "jesusch/php-queue": "*"  
    },
    // ...
}

2. Run composer install.

3. If you haven't already, add the Composer autoload to your project's initialization file. (example)

require 'vendor/autoload.php';

Jobs are queued as follows:

$queue = new \JobQueue\Queue();
$queue->setMaxProcs(10);

$job = new \JobQueue\Job();

$queue->appendJob($job);

$queue->waitForJobs();

Each job should be in its own class, must extend \JobQueue\AbstractJob and include a public run method.

class My_Job extends \JobQueue\AbstractJob
{
    public function run()
    {
        
        // Work work work
        echo 'some fancy job';
        $sleep = rand(1,5);
        sleep($sleep);
    }
}
