mwGearman

Version 0.1.0 Created by Mike Willbanks

Introduction

mwGearman is a module that handles interfacing with the Gearman extension. This module presently can handle client and worker communication and abstracts portions of task handling. The overall goal is once Zend\Console has been completed to integrate workers into the Console to make building out gearman worker models far more simplistic.

Requirements

• Zend Framework 2 (beta4+)
• PECL Gearman

	    }
}

Git Submodule

• git submodule add [repo-url] ./vendor/mwGearman
• add 'mwGearman' to your application.config.php file

Usage

DI Configuration for Connection Handling

<?php
return array(
    'di' => array(
        'instance' => array(
            'mwGearman\Client\Pecl' => array(
                'parameters' => array(
                    'servers' => array(
                        array('localhost'),
                    ),
                ),
            ),
            'mwGearman\Worker\Pecl' => array(
                'parameters' => array(
                    'servers' => array(
                        array('localhost'),
                    ),
                ),
            ),
        ),
    ),
);

Submitting a Job to Gearman

<?php
$gearman = $serviceMananger->get('mwGearman\Client\Pecl');
$gearman->connect();

$workload = 'some-string';

$task = new mwGearman\Task\Task();
$task->setBackground(true)
     ->setFunction('myJob')
     ->setWorkload($workload)
     ->setUnique(crc32($workload));

$handle = $gearman->doTask($task);

Retrieving a Job from Gearman

<?php
$gearman = $serviceMananger->get('mwGearman\Worker\Pecl');
$gearman->register('myJob', 'handleJob');
$gearman->connect();
while($gearman->work());

function handleJob($job) {
    $workload = $job->workload();
    echo $workload;
}

Roadmap

• Integrate Net_Gearman from PEAR
• Integrate Zend\Console for a BaseWorker
