delete all files in a drirectory php script

I need a script that will run via a cron job written in php to delete all the files in a directory. VEry easy for someone who know php. I'll use GET <[login to view URL]> to run the cron job. The script will have to delete all files in a directory that I assign and have a little error handling so it does not kill the server if no files are found. Again should be a quick job for the right person.
