It's only like 2% done, but I want to see what people think of the idea. Basically what I am doing is going through the official documentation and creating sample code for each method. Comments are enabled for the entire site (except for the homepage) so I am hoping to get some good discussion started. The site is loosely modelled after the php.net documentation. The site is targeted at beginners, experts will have little use for it.
