This article by Tony Marston is an important one since it deals with the best practices of OO programming. I could say the article is not language specific but since he mostly deals with PHP and MySQL, the codes are based on PHP. Describes topics such as Data Dictionary, Entities, and OOP pagination system. He also shows how to store the state of an object in one page and then “resume” that state in another PHP script by using PHP’s built-in session object. Pretty neat, huh?
