IBM has just published the Redbook that I wrote with a team of IBMers from across the globe in San Jose earlier this year.
The book had three goals; to demonstrate best practices for developing PHP applications with IBM database servers, to provide detailed instructions for administrators to set up all the required software, and to help users migrate from MySQL to DB2.
I expect you will all dedicate your long weekend to reading it. It makes an excellent beach or barbecue companion. :)
