The Zend Developer Zone site has posted a review of a recent Day Camp 4 Developers event, specifically the PSR-7 presentation from Matthew Weier O'Phiney (PSR-7 is the proposed standard for HTTP request/response interfaces).

Having a keen interest in PSR-7 myself, I was delighted to see that Matthew Weier O'Phinney (the Supreme Allied Commander of Zend Framework) was going to be speaking on it himself at the latest Day Camp 4 Developers day. [...] PSR-7 deals with specifying interfaces to define HTTP messages (namely request and response messages), and in this talk Matthew introduces the concepts around HTTP messaging, and the PSR-7 implementation that models them. Matthew is the current editor of the proposed PSR-7 standard so this talk was obviously going to be given straight from the horse's mouth.

The author (Gary Hockin) walks you through the content provided in the video including:

• an overview of the proposal
• how other languages solve the same problem
• how PST-7 will solve these same problems

Overall Gary found the talk well-presented and full of good content, especially for those just learning about PSR-7. You can find out more about Day Camp for developers and future events on their site.
