The Wrong Way?
Well...kind of.

OOP will not magically make your code better.
As a methodology, OO has issues.
It's still good to know.

Common patterns
Front Controller
Front Controller
- Used in non-OO applications (Drupal, Wordpress, Joomla)
- One file routes all requests to the code that should handle that request
- Usually involves some kind of URL munging by the web server
MVC
MVC
- Models: Represent data your application cares about (sometimes correlates to database tables)
- Views: Present information to the user (templates)
- Controllers: Orchestrate the process of getting data from Models and outputting the data via a View
