On the Zend Developer Zone there's a recent post about a contest they're running to give one lucky winner a free pass to this year's Zend/PHP Conference in November in Santa Clara, California.
Summer is upon us, which means that the annual Zend/PHP Conference (ZendCon), the world's largest gathering of the PHP community, is drawing near. Preparations are already in high gear, and you can make an impact on what fellow PHPers will wear in Fall of 2010! Submit your cool t-shirt designs or just cast your vote. The winning design will be used for the new 'official' PHP t-shirt. Every ZendCon attendee (and some others) will be getting the free t-shirt, and you get a free pass to the conference!
Besides the ticket to ZendCon, there's also two other prizes for the runners up - a free pass for a Zend Certification Exam (5.3) and a pass for a Zend Framework Certification Exam. There's about seven weeks left to submit your design and are currently eight entries on the list, so get your design in early to give it the best chance for the most votes. The submission round will end September 30th, so get your designs in soon!
