In this post from his blog, Justin Silverton takes a quick look back at the November meeting of a few of the main PHP developers on what needs to happen in PHP6.
In November of 2005, the major developers working on the core of PHP met up in Paris and discussed various additions that would possibly make version 6.
Attendees included Wez Furlong, Derick Rethans, Rasmus Lerdorf, and Zeev Suraski and some of the topics that were discussed included: filename encoding, optimizing the use of brackets in strings, and register_globals.
Of course, some of these issues have already been worked out of the PHP builds and will be coming to a web server near you with a whole new feel.
