Zend Framework Cron for FIFO Queue

Question

I am trying to run a cron job in my application my set up is like this: My zend application Version 1.12

inside my public/index.php

function Mylib_init_settings($settings, $environment)
{
    if (getenv('LOCAL_ENV') && file_exists($serverConfigFile = __DIR__ . '/../application/configs/' . getenv('LOCAL_ENV') . '.ini')) {
        $settings->addOverrideFile($serverConfigFile);
    }
}

define('MYLIB_APPLICATION_ENV', 'production');
require __DIR__ . '/../library/Mylib/Application/start.php';

Inside Start.php

<?php
use Mylib\Config;
use Mylib\Config\Loader\SecondGeneration;
function mylib_trigger_hook($hook, $params = array())
{
    $func = 'mylib_init_' . strtolower(trim($hook));
    if (function_exists($func)) {
        call_user_func_array($func, $params);
    }
}

    if (MYLIB_APPLICATION_RUN) {
        $application->run();
        macq_trigger_hook('run', array($application));
    }

}

What I did is :

I followed the following link: http://www.magentozend.com/blog/2012/02/03/setting-up-cronjobs-for-zend-framework-envoirment/

what I did is create a "cron" folder at the level in which my application folders are present.

inside the folder created init.php file inside that I added my index.php code and start.php code.

and my controller file is as like this:

application/modules/myproject/controller/cronjop.php

inside the cron job file I just called init.php by

require_once('/../../../../cron/init.php');

but the cron is not working can some one help me..

thanks in advance..

it has nothing to do with zend just open is as normal PHP site. Show your crontab. — Robert
If you echo something after the $application->bootstrap(); line, do you get output then? — Tim Fountain

I see you miss the point of using Cron and Zend as well. Zend site is just normal site so you can use for example lynx browser to run the site.

 */10 * * * * lynx -dump http://www.myzendsite.com/mycontroller/mycronaction

just create My Controller add mycron Action and put in this method what you want cron to do. Lynx will open it as normal user would do. Cron will run lynx after some time.

The line */10 means every 10 minutes. You can fit it to your needs.

There are other ways to run php script for example via php parser or curl.
