"What? A PHP coding contest. This is your chance to show off your skills to the whole world.
When? A new contest every month or so.
Why? To prove you can do it. You will get recognition on the front page of codewalkers.com, and if you have a web site it will be listed also. Your winning code will also be posted on Zend.com in a special section of their code gallery.
Give me some details! All you have to do is check out the current contest and then code it. All submissions must be PHP only. Yes, HTML is allowed. Yes, any extension commonly available to PHP is allowed. Disallowed is any other type of scripting language (server-side or client-side)."
