Basically, a "Simple OO Example" is an oxymoron, or a Bad Example (apologies to Ralph Covert). OO really only shows its strength when you have a certain set of pre-conditions: 1. Multiple programmers working on large-scale project -- OO safely sub-divides functionality so that they can code with less risk of screwing each other up. 2. "Library" release code (eg PHPLib) -- OO allows you to have minimal impact on the main application's variables/constants etc by providing a separate name-space 3. "Real-World Object" being modeled in complex/interesting ways -- OO provides a more "natural" coding style for this in some cases. None of these pre-conditions is met in a "Simple Example" That said, there are a zillion PHP OO applications/solutions "out there" for you to look at. Some even have comments. A few even have *GOOD* comments. :-) It is entirely possible, however, that you don't even *NEED* OO for anything you're doing. If your project doesn't meet any of the above three pre-conditions, chances are Really Good that OO would be like swatting a fly with a cannon. You can do it. And if a cannon is all you know how to work properly, maybe that's the best answer. But it's usually not the "best" answer in a general sense. NOTE: I'm an old-school Lisp hacker. I *LOVE* Object-Oriented systems. Yet I rarely feel a need for OO in my PHP scripts. YMMV. -- Like Music? http://l-i-e.com/artists.htm I'm looking for a PRO QUALITY two-input sound card supported by Linux (any major distro).
