How does a cronjob work? [Easy Guide]
Now suppose I have a webapp which makes temporary xml files when user logs-in and stores their activity till they are online. When the leave the webapp, or remain inactive for about a hour, I want to delete them. So, how to i instruct my server to delete them ? How do I tell my server “Go Delete All Messages every 1 hour” ?
In this case, I make a php script which deletes those files when run. Then I setup a cronjob to run that php file every 1 hour/60 minutes/3600 seconds automatically.
