Best PHP source to build a CMS with user-based roles
What would be the easiest to understand and implement quickly PHP book that goes in depth of bulding a content management system (where a user can insert and retrieve records from a mysql database with a GUI that allows them to make queries) with user authorization (e.g. user must sign up to and be of role type A or B to access page to make query), and preferably using some type of MVC diagram? What I don't need is another PHP book that just explains the syntax of the language with no practical in-depth examples of building a CMS. Thanks for any response.
