To each their own I guess. Just out of curiosity, are you primarily writing entire web applications or one off scripts? I used to say "you don't need all that" but over time I just can't say it much anymore. It seems easy to just dive in and throw something out the door, but then new features need to be added. One of my favorite programming books, Design Patterns Explained, says "Change happens! Deal with it." Using patterns helped me do just that with minimal crying because the underlying architecture could be easily modified. Also maybe look at Head First Design Patterns if you are interested in ever understanding them. Most of the books I've read say something along the lines of it should be obvious when to use these patterns when you read their book. This might be true for some/most people but I couldn't get my head wrapped around them till I read Head First. Seeing their examples with the fun writing just made things click for me. After reading that not only could I use them, but I started spotting them in peoples code. Another benefit of knowing patterns is having a common language for explaining solutions to problems between developers. Saying I'm using the decorator pattern makes much more sense then saying I'm wrapping this thing with another thing that makes it do something else so I can swap out behaviors because they work together, etc. ...but that is just the world I like to live in. :) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
