I am working on a PHP login system but I am stumped. The system right now can do the following: 1) User can create an account 2) User can confirm their e-mail address 3) User can login to the account and see member-only pages The problem is that once a user logs in and sees the web pages that only registered users can see, they can only see it once. Once they leave the page, they have to login again. I know you have to use $_SESSION and session_start() but I am confused. Can someone please assist? Also, if there is an already developed login system for PHP that is similar to the ASP.NET 2.0 Membership system, can you please let me know?
