This code is designed to accompany the lynda.com video course "Design Patterns in PHP" by Keith Casey. If you've received this code without seeing the videos, go watch the videos. It will make way more sense and be more useful in general.

======================

In each of the numbered folders, you will find a few directories. The first folder - called before - is what your code might look like before the pattern. While it's not beautiful, it isn't necessarily wrong.. but it can be better. After exploring the "before" folder, check out the "after" folder to see what the code might look like after a bit of refactoring for the design pattern. This isn't the only possible solution or implementation. It just happens to be the one I chose to share.
