Tobias Schlitt has covered the PHPWeekender event that happened this past weekend in two new posts over on his blog:
Day one (10.07.06) saw the start of the meeting, and included a three hour tutorial session giving people a crash course to what PHP is and how it functions at a basic level. Pizza for lunch, then right back into the classes - more basics, some XML talk, and XML-RPC/REST/SOAP as well (two different tracks).
Day two (10.07.06) is described in this post along with a summary of how the event went and the feedback from those attending. Topics today included best practices, PHP5's advanced OOP features, "Enterprise PHP", and a final keynote.
Keep an eye out on the PHPWeekender website for complete information, slides, and examples from the event as well.
