I’ve put together this simple bootstrapper file that you can use to directly run your CodeIgniter controllers from the commandline. It’s a very easy and elegant solution for using CI controllers for cron jobs. It also supports logging.
Note: this file must have UNIX-style line breaks. If you try to run it and it complains “Invalid interpreter: /usr/bin/php^M” then you probably need to convert your line breaks.
#!/usr/bin/php

| CRON JOB BOOTSTRAPPER
|--------------------------------------------------------------
|
| This section is used to get a cron job going, using standard
| CodeIgniter controllers and functions.
|
| 1) Set the CRON_CI_INDEX constant to the location of your
| CodeIgniter index.php file
| 2) Make this file executable (chmod a+x cron.php)
| 3) You can then use this file to call any controller function:
| ./cron.php --run=/controller/method [--show-output] [--log-file=logfile] [--time-limit=N]
|
| GOTCHA: 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.
