Thread:Extension talk:DailyFeaturedPage/How do I make it rotate articles without editing the php file

How can I make it change to a new article every day without having to edit the PHP file. For example:

I want to display a random article from a collection of articles with the same category, but I don't want to have to edit this php file just to add new article names. I want the new article to change at midnight every day.

Is there a way to do this without a lot of case statements?

Thanks, W
