Write some Software

I need a short snippet of code for my existing home page that will call different content (image, text and links) into the same div / block every 24 hours, as determined by calendar date at my end. There are 72 different sets of daily content to cycle through, that when a cycle is complete, begins all over again. I'd like the file that contains all 72 pieces of unique content to be in a file that's called with php. I don't need you to code the content for the 72 - once I know how to format it, within the php file, I can do / replicate that 72 times. I just need the working code for it all to do what I want it to do. I've built my own website with Dreamweaver. Just don't know any php ... nor found any plugins that'll do this ... Thank you!
