Implementing ACL for my PHP application

Question

My RealEstate PHP Application have following user groups,

Admins, Moderators Agents

i want to specify following permission to the following users.

Answer 1

The way that I have done this in the past was to create a users table in the database that had an access level (Admin, Moderator, and agents).

Then if you have a menu system, implement a check to see what privileges are needed for what links... Admins will see all links, Moderator will only see links he/she is supposed to, and agents will only see what they are supposed to see.

Also on the pages that you may want to restrict users you will want to check for the users access level. If they pass, they will see the page, if not, they will be redirected or a javascript error will need to pop up.

Something like the access level may do you some good to store it in a cookie as you can cut down your calls to your database.

Hope this helps, Mike
