Andi Gutmans has a note of celebration on his blog today - the book that he, Stig Bakken, and Derick Rethans worked on, "PHP 5 Power Programming", has officially passed one million downloads.

A few days ago I was informed that the PHP 5 Power Programming book has now been downloaded over 1 million times. Exposure no doubt. And considering that there are about 4.5 million developers out there, it's safe to say that probably between 1 in 5 PHP developers have actually laid their hands on it (or should I say their computer screens on it).

Andi mentions also being happy to see this milestone crossed for many reasons, one of which that it's a sign of the PHP community maturing. To grab your copy, check out this page on phptr.com.
