PHPMyibill

PHPMyibill is a PHP4/MySQL-based program that allows a membership based site to manage its users and let them automatically sign-up using credit card via the Ibill system. The webmaster can, via the administration page, see in real time how many members sign-up daily, edit or delete users, e-mail all of them at once, set users active or inactive, etc. On the user side, customers sign-in only once per session to access all your protected pages. If they forget their password, they can have it e-mailed to them automatically without your intervention. Limited scope installation available for free.
