| 19 | * Web cron | |
| 20 | * | |
| 21 | * This script looks through all the module directories for cron.php files | |
| 22 | * and runs them. These files can contain cleanup functions, email functions | |
| 23 | * or anything that needs to be run on a regular basis. | |
| 24 | * | |
| 25 | * This file is best run from cron on the host system (ie outside PHP). | |
| 26 | * It is strongly recommended to add password protection via admin settings. | |
| 27 | * | |
| 28 | * eg wget -q -O /dev/null 'http: *moodle.somewhere.edu/admin/cron.php?password=SeCreT666' | |
| 29 | * | |
| 30 | * It is also possible to use CLI script admin/cli/cron.php instead, | |
| 31 | * you can not call this script from command line any more. | |
| 32 | * | |
| 33 | * @package core | |
| 34 | * @subpackage admin | |
