[PHP] Automated Scripts

[Tait Grove at DIGITAL]

I need to run a script that renames a file and deletes an old one then ships it to 
another server every Monday at a certain time.... I know this is possible, but what is 
the technology called? Does PERL or PHP have the ability to do this? Can I get CRON 
objects to run PHP source code?

PLEASE HELP!!!
