Ive built a script which allows me to add domains which have a name, expiration date and the date it was registered. However everytime i log into the admin panel i would like it to show me all domains which are about to expire in a supplied time.

However im unsure how i would go about doing it. Ive had an idea using the time() function but i would like it to be user friendly so they could just enter a date like 11/11/05.

Thanks in advance,
Simon

Can you give me any less information to work with?
