#Codeigniter Gearman Library

This is a library to use gearman within codeigniter. The original source was pulled from Sunil here https://github.com/sunils34/codeigniter-gearman-library. I add some feature and remove deprecated function.

Please make sure you have setuped gearman daemon environment and gearman pecl drivers. (http://pecl.php.net/package/gearman).

##Set up gearman environment

For Ubuntu/Debian OS (apt-get install):

install gearman server

$ aptitude -y install gearman gearman-job-server libgearman-dev libdrizzle0

install gearman extension

$ pecl install channel://pecl.php.net/gearman-1.1.2

Installation

You can install via http://getsparks.org/packages/codeigniter-gearman/show

$ php tools/spark install -v1.0.1 codeigniter-gearman

or manual install

$ cp config/gearman.php your_application/config/
$ cp libraries/lib_gearman.php your_application/libraries/

Usage

load library from spark:

$this->load->spark('codeigniter-gearman/1.0.1');

or load library from manual install:

$this->load->library('lib_gearman');

Client Example

Please refer: example/cli.php

public function client()
{
    $this->lib_gearman->gearman_client();

    $emailData = array(
        'name'  => 'web',
        'email' => 'member@example.com',
    );
    $imageData = array(
        'image' => '/var/www/pub/image/test.png',
    );

    $this->lib_gearman->do_job_background('sendEmail', serialize($emailData));
    echo "Email sending is done.\n";
    $this->lib_gearman->do_job_background('resizeImage', serialize($imageData));
    echo "Image resizing is done.\n";
}

Worker example

public function worker()
{
    $worker = $this->lib_gearman->gearman_worker();

    $this->lib_gearman->add_worker_function('sendEmail', 'Cli::doSendEmail');
    $this->lib_gearman->add_worker_function('resizeImage', 'Cli::doResizeImage');

    while ($this->lib_gearman->work()) {
        if (!$worker->returnCode()) {
            echo "worker done successfully \n";
        }
        if ($worker->returnCode() != GEARMAN_SUCCESS) {
            echo "return_code: " . $this->lib_gearman->current('worker')->returnCode() . "\n";
            break;
        }
    }
}

Define job function

public static function doSendEmail($job)
{
    $data = unserialize($job->workload());
    print_r($data);
    sleep(2);
    echo "Email sending is done really.\n\n";
}

public static function doResizeImage($job)
{
    $data = unserialize($job->workload());
    print_r($data);
    sleep(2);
    echo "Image resizing is really done.\n\n";
}

$ php app/index.php cli worker
