Like most complex subjects, design patterns are best learned over a period of time, not in a few sittings. Eric Freeman and Elisabeth Freeman, coauthors of Head First Design Patterns, suggest one way to ease the learning curve (and have some fun along the way): form a study group, using their book. If you're ready to get your engineering team together, the Freemans get you started in this article with a plan to follow and chapter-by-chapter questions to help generate discussion.

Simple web apps can start simple, but when they grow more complex, they often need pruning and refactoring to be maintainable. The Page Controller design pattern can help separate concerns such as templates and logic. Ethan McCallum demonstrates this language-neutral technique with PHP.
