Category-Proposal: Patterns

Hi everybody! Since i learned "real" programming with PHP i do not really know much about patterns. But the point is i'd liked to. Because of this i thought about a new category on the PEAR website. What about a collection of patterns and their implementation in PHP? I think that'd be very usefull for everyone who's not so skilled on programming. Maybe there are some patterns which only exist in PHP. What does everone of you think about that? Thanks for your feedback!
