Authentication programming

Hi, I'm about to start a new project which will require a login system. The system should allow for different types of access on a per page basis. I'm going to achieve the login system using sessions, which I have done before. My problem is that I don't want to have to do much login checking on the actual pages within the system. I would like it to be included and handled oustide of the main application. <?php /* authenticate */ $page_permission = 'admin'; include('includes/login.inc'); /* other page functionality */ ?> So, you set the permission for the individual page. I would also like to do this as a class, which I am not experienced in. I haven't found any very elegent solutions to this. Could anyone point out some urls or anything to show me in the right direction? Cheers, Jord -- Jordan Elver There's no 'I' in 'team'. But then there's no 'I' in 'useless smug colleague', either.
