Creating a schedule

[bigfella]

Hello,

I am building a diet/weight loss website where a customer would
subscribe for 1,3,6 or 12 months. I am using Paypal IPN to handle the
subscription payments. I would like to create a schedule when the
customer first logs on, from the date they signed up to the date when
the subscription ends and every 7 days is highlighted as the weigh in
day.

Basically I would like to generate a list of dates from one date to
another with every 7th day highlighted.

From Paypal I get the following info recur_times :- The number of

payment installments that will occur at the regualar rate. I also have
the date when they signed up. Both in a MySQL database.

Many thanks

Darren
