Suggestion on how to deal with different user right

I have a page which have different version, one is member, one is admin, and one is guest. You may know what is the different, if the user, they have: login button register button

if the user is a member, they have: logout button edit button in they conten开发者_如何学编程t

and the admin, will have: logout button banned button for all content

So, my question is, they are similar content, show I make 3 separate page? or one page to do all this stuff? Thank you.

I suggest you use one page and use ACL to define what every user can do. I heard ZEND_Acl is a good start.
