One of the biggest challenges for PHP programmers just coming in off the streets (so to speak), is changing from a procedural way of programming into the infamous OOP style (Object Oriented). This leap can be made quickly and somewhat easily with the help of a few friends - and articles like this one from DevArticles to help.

Unfortunately, there hasn't been a good, solid OOP tutorial posted out there yet (that I've seen), but this new article comes close to showing you how to get the ball rolling with objects. It explains more of the terminology behind the objects (something a few others completely leave out), and gives examples of each - things like constructors, overloading, and even polymorphism.

They briefly get into some mention of the structure behind these classes, but don't really show any "real life" examples. Personally, I'd love to see a "part two" to this article, with more examples and structure details on the terms and contents of this article.
