I've been trying to create a specialised CMS, as none of the current open-source ones fit my needs for this project.

I'm trying to create a CMS for a TV/episode guide which is similar to this:

(one such example) - where records expire and delete from the database after expiration.

This is the type I'm trying to emulate:
(a TV guide description of programme)
(a typical episode, could use .htaccess)
(paginated episode display, auto-deleting when record expires)
I don't have access to cron job, so that's out the question for this one.

I'm not sure how to go about this successfully, anyone got any advice?

(Note:Although the linked site runs in ASP.NET, it's the design and feel of it I'm trying to emulate, except in PHP)

I should add, I tried with what I gleaned from searching, but it didn't quite work out.

I'm only a beginner at this, but it's a skill I feel I could get better at.
