On the KillerPHP blog today, Stefan Mischook has written up a book review of a popular book from Sams Publishing - "PHP 5 in Practice" by Elliott White and Jonathan D. Eisenhamer.
This is a very good book, actually one of the best recipe books I've read period. You can tell that the authors are still actively writing code - you can feel it as you read the chapters.
The review also lists out some of the contents of the book including sample recipes and the "quick hits" section.
