integrating paypal

automating subscriptions to my site

What is the best way to go about keeping website subscriptions to my site automated, as well as when a user's subscription runs out automatically reverting the account to the standard version...

I'd like to write a script to keep the whole process automated... like, how can i keep my users correllated with their paypal payments? This has to be possible. Can i pass a variable along with a pay-pal payment, like the user's username and what not?

The thought just occured to me that i can have a column in my database with the date their subscription ought to expire... just add the '6 months' or whatever to the current date... but that still leaves me with the issue of automatically activating their premium services upon payment. Any thoughts? Thanks a lot.

I have a working knowledge of PHP, so this shouldn't be too hard for me to figure out :)

Zend has a great tutorial - worked fine for me:

Thankyou for this.

This should set me along the right track.
