I recently completed my first web application using PHP and MySQL. It basically allows users to update scores and other information using a database. I'd like to add it to my porfolio but seeing as anyone would be able to change values in that case, i'd like the database values to be reset periodically. I'd say, every 20 minutes to an hour or so. What's the best way to accomplish this task?
Ideally, I would only want it reset if values had changed but if that's too complicated, a clean wipe every so often would suffice.
I'm running Linux shared hosting with GoDaddy as far as server specs.
Any advice would be much appreciated.
