Chris Shiflett has started up a PHP project for the holidays - a PHP Advent Calendar to share helpful hints and knowledge from members of the PHP community:

Welcome to the PHP Advent Calendar. If you are unfamiliar with the format of an Advent calendar, Wikipedia has a pretty good description. The PHP Advent Calendar is similar in spirit to the Perl Advent Calendar, a tradition the Perl community has sustained for several years.

So far he's posted the first (Sean Coates) and second (Elizabeth Naramore) days. Keep an eye on his blog for more holiday PHP goodness!
