Say the you are going to create a simple forum and you want to have a number of classes:
Class Sql - handles the DB interface Class User - handles users Class Messages - handles messages When you are writing the code, you first creates a new sql object in order to read or write data from or to the database. Secondly you create a user object in order to handle users, for an example, to authenticate the user which is going to write a new message in your forum. The user object have a method which reads user information from the database. Since you alread have created a sql object, this method should use the sql object in order to fecth data from the database. I nice way to do this, would be to send the sql object as an reference to the user object constructor and store the object reference to the sql object in the user object. This is not working very well in PHP yet because PHP cannot treat objects as references. When you send the sql object to the user object constructor method, it will be a copy, not a reference! How do I get around this? There must be a way to handle this and create nice OOO PHP-code? I don't like using global variables as object handles.
