Brian Swan (of Microsoft) has posted his wrapup of the recent Jump In! Camp they held around integration of SQL Server functionality into several popular PHP projects like the Zend Framework and PEAR.
During each day of the camp, PHP developers worked side-by-side with Microsoft developers to add SQL Server and SQL Azure support to their projects, but nearly everyone put in many extra hours late at night (and even early morning!) to add support for other Microsoft technologies (such as IIS, Web Platform Installer, and Windows Azure).
I can’t say thanks enough to all the participants for being 100% invested in the camp and for going the extra mile to investigate how their projects might be able to integrate Microsoft technologies beyond SQL Server and SQL Azure. I know that the entire SQL Server team echoes my thanks.
