As Chris Jones mentions on his blog today, the "Underground PHP & Oracle Manual" has gotten a bit of a facelift:

Thanks to the Oracle Technology Network design team our very popular, free Underground PHP & Oracle Manual has had a makeover and gained a snazzy new front cover. Farewell to the photo of the underground car park door that used to greet me each night on the way out of the office.

The book not only has a new cover but it also has a new page where you can download the latest copy. (The contents of the book haven't changed since the end of last year, though.)
