Jeremy Kendall has started up a new blog that's a sort of "WTF in PHP" listing of some of the random (and bad) code that he comes across daily - CSI:PHP.
It all began with a new gig and an amazingly horrific codebase. I began tweeting the most unbelievable, most frustrating snippets I could find. After quite a few of those tweets, Chris Hartjes replied with, "Looking at your tweets I cannot even fathom what your job is. CSI:PHP ?" A concept was born.
Some of the posts so far include eval() hell, a bad use of preg_replace and a bad method for calling mail(). Currently there's not a way for others to contribute their own code WTFs, but from what I hear it's possible for the future.
