How to execute a CakePHP controller's action from a cron job

First copy webroot/index.php to **webroot/cron\_scheduler.php**. Replace everything below **require CORE\_PATH . 'cake' . DS . 'bootstrap.php';** with the following code: ```php # # 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 $ php cron_scheduler.php /controller/action ``` If you get the following error, remove the lines containing line feeds in bootstrap.php: ```php Warning: Cannot modify header information - headers already sent by (output started at .../app/config/b ootstrap.php:48) in .../app/app_controller.php on line 46 ```
