It’s easy to configure a cron job in cpanel, in order to run a php script automatically. You must know the physical path of the script. That will be:
/home/username/public_html/folder/filename
Replace username, folders and filename.
And the php path, which will be /usr/local/bin/php
The command will then be:
/usr/local/bin/php -f /home/username/public_html/folder/filename
Configure the time settings. And it’s done.
