Simple PHP script to change text on website weekly

I need a simple script to swap a chunk of pre-defined HTML text on my website every week. Every week I manually post a schedule for our organization by editing the HTML code in Dreamweaver. I would like a simple (I think PHP would work best for this) script that I can insert anywhere into the site which would then show that weeks information. The script would change the info for the next week every Saturday Night, at 11:59 PM. This would have to be coupled with a database of some sort to store every week's info. I just need it to be easy to edit, so you can use a simple text file if you'd like. If you want to use MySQL that is fine as well but you will have to show me how to edit the file with the information in either case. If you'd like you can build a web-interface, but for a lower cost I am perfectly fine editing some code (once instructed) and using text files. ------------------------------------------------------------- I don't think this should be a hard project, as you can build on open-source code for Quote displays: [login to view URL] Money is an issue as we are a non-profit so please keep that in mind. --------------------------------------------------------------- BONUSES: If you can do these let me know, they would make the script better for me: 1. Could I choose exactly when the script "refreshes", i.e. gets the next weeks information from the database and it displays it? Even if this is a line in the PHP script to edit, that would be useful. 2. Could I run copies of the script? For example, 1 script, named [login to view URL], would show schedule info weekly, while the same script named [login to view URL] (with some simple changes) could run a monthly schedule, or anything I'd like. 3. An optional line on the bottom printing out when the script was last refreshed, and when it's next refresh date/time is, would be helpful, but is not required. ------------------------------------------------------------- Thanks and let me know if you have any questions.
