| CRON JOB BOOTSTRAPPER
|--------------------------------------------------------------
|
| By Jonathon Hill (http://jonathonhill.net)
| CodeIgniter forum member "compwright" (http://codeigniter.com/forums/member/60942/)
|
| Created 08/19/2008
| Version 1.2 (last updated 12/25/2008)
|
|
| PURPOSE
| -------------------------------------------------------------
| This script is designed to enable CodeIgniter controllers and functions to be easily called from the command line on UNIX/Linux systems.
|
|
| SETUP
| -------------------------------------------------------------
| 1) Place this file somewhere outside your web server's document root
| 2) Set the CRON_CI_INDEX constant to the location of your CodeIgniter index.php file
| 3) Make this file executable (chmod a+x cron.php)
| 4) You can then use this file to call any controller function:
|    ./cron.php --run=/controller/method [--show-output] [--log-file=logfile] [--time-limit=N] [--server=http_server_name]
|
|
| OPTIONS
| -------------------------------------------------------------
|   --run=/controller/method   Required   The controller and method you want to run.
|   --show-output              Optional   Display CodeIgniter's output on the console (default: don't display)
|   --log-file=logfile         Optional   Log the date/time this was run, along with CodeIgniter's output
|   --time-limit=N             Optional   Stop running after N seconds (default=0, no time limit)
|   --server=http_server_name  Optional   Set the $_SERVER['SERVER_NAME'] system variable (useful if your application needs to know what the server name is)
|
|
| NOTE: Do not load any authentication or session libraries in controllers you want to run via cron. If you do, they probably won't run right.
|
