When looking at tutorials and tips, you'll hear phrases like "the objects 'x' method" and "returns an 'x' object". If you're not sure what this means, it definitely helps to get a grasp of the concept of objects when you are programming.
A big problem I had when I first learned about Object Oriented Programming was that tutorials all needed to be so damn correct. Since I was only a noob this lead to confusion and frustration.
This post is not entirely correct, and in some ways just flat wrong. But it serves to bridge the gap between procedural programming and OOP for the newbie. If you continue down the golden path of OOP you'll find that a lot of the stuff I said here was fallacious, but it was a means to an end.
