Helpful PHP Codes for Efficiency

1. Clean Logs Created Under /home

If you need to clean all logs created under /home with filenames like cron.php?2323 every 12 hours, you can achieve this using a cron job.

Step 1: Create a file named clean-cron-logs.php and add the following code:

array_map('unlink', glob("../cron.php?*"));

Step 2: Add this file to your cron jobs:

/usr/bin/php /home/public_html/clean-cron-logs.php

This setup ensures that all matching log files are deleted every 12 hours.

2. Change Moodle’s Root Path

To change Moodle’s root path, you can modify the config.php file.

Step 1: Locate the line below in config.php:

$CFG->wwwroot = 'http://yourdomain.com';

Step 2: Change it to the desired path:

$CFG->wwwroot = 'http://yourdomain.com/the_path_to_be_the_root';

Remember to comment out the previous line to keep track of the change:

//$CFG->wwwroot = 'http://yourdomain.com';

3. Dynamic Root Path Based on Domain

To set Moodle’s root path dynamically based on the client’s domain, you can use the following code:

if (false !== strpos($_SERVER['HTTP_HOST'], "yourrefdomain")) {
    $CFG->wwwroot = 'https://yourrefdomain.com';
} else {
    $CFG->wwwroot = 'https://yournormaldomain.com';
}

This allows Moodle to serve different root paths depending on the domain from which the client is accessing the site.
