I was wondering if there was a way to create a sort of cronjob without actually having to add a new cronjob? I'm not sure if it would be possible in PHP/MySQL or if it would be better created in a dynamic scripting language.

Basically, I want to create an addition to my script that allows it to control cron's without having to rely on that server being setup with a cron tab or the user knowing how to use them. Any suggestions or pointing in the right direction would be greatly appreciated.

-Thanks (=
