Tagged cakephp, cron, job  Languages php

First copy webroot/index.php to webroot/cron_scheduler.php. Replace everything below require CORE_PATH . 'cake' . DS . 'bootstrap.php'; with the following code:

#
# BEGIN
#
# This was added to webroot/cron_scheduler.php
#

# Check that URI was specified and that we're called from the command line (not the web)
if($argc == 2 && php_sapi_name() === "cli") 
{
    # Set request URI
    $_SERVER['REQUEST_URI'] = $argv[1];
    # Set user-agent, so we can do custom processing
    $_SERVER['HTTP_USER_AGENT'] = 'cron';
    
    $Dispatcher= new Dispatcher();
    $Dispatcher->dispatch($argv[1]);
} 

#
# END
#
# 
#

Now you can execute CakePHP from the command line with the following command:

$ php cron_scheduler.php /controller/action

If you get the following error, remove the lines containing line feeds in bootstrap.php:

ootstrap.php:48) in .../app/app_controller.php on line 46
