As is mentioned here on Ben Ramsey's blog and here on the Zend Developer Zone - the "official" shirts of the PHP community channel on freenode, #phpc, have been created and can be ordered.

Ben notes that the decision was made to create the shirts because of the good number of #phpc-ers that were attending the Zend/PHP Conference and Expo this year. The design has been created and the order will soon be placed, so if you want to get in on the order, let Ben know (via email - tshirts [at] benramsey.com) and they'll add another name to the list. The cost on them is about $13 USD.
