A simple, light-weight Codeigniter 2.0 CLI / CRON / Boot-strap loader script. Access your controllers from the command-line, helping you to effectively utilize your models / libraries and other code efficiently.

This package is based loosely on the codeigniter CLI script written by Jonathon Hill. It has been greatly modified, modularized & updated to support multi Web site implementations, more CRON specific tasks, and of course, it has been tailored to run with CI 2.0.

We elected to utilize the MVC style of CI to better suit our needs and so we use a "bootstrap" style PHP script to start our CI environment.  We have stripped the script down to where it is generic enough to support any web site you might need it for. 

If you want the script to support multiple web sites, wish to only maintain one copy of the script and are not using symbolic links to accomplish this - you'll need to modify the script slightly to capture an additional parameter VIA command-line: the application folder name. It is a simple modification, but if you are having a problem accomplishing it, please feel free to contact us for help.

Installation

1. Download the compressed package above, which contains the cron script, the config file & the example controller and save it anywhere on your server.
2. Unpack the package and merge the files into your desired CI installation.
3. Modify the cron.php file in the application/config folder to match your site installation.
4. Ensure the the cron.php file in the system/cron folder has execution permissions with the command: $> chmod +x cron.php
5. Run the cron script from command line with the command: $> php cron.php

* Note: if you plan to use more than one controller you can remove the config over-ride array and then supply the controller and method VIA command line with the command: $> php cron.php controller/method
