I'm hoping for a few recommendations on simple GPL OOP projects that I can inspect the source code to learn from. I'd like to keep the relative complexity low. The main things I'm looking for are:
  • What coding standards did they use?
  • What logic did they employ
  • directory structures
  • the templaing (if any) system
  • just a chance to read other people's well-written, OOP PHP code

Any suggestions? Thanks!
