ACKNOWLEDGEMENTS

This book could not have been written without feedback from our technical
reviewers; therefore, we would like to thank Marcus Börger, Steph Fox, Martin
Jansen, and Rob Richards for their excellent comments and feedback. Besides
these four reviewers, there are a few more people who helped answer several
questions during the writing of this book, more specifically Christian Stocker for
helping with the XML chapter, Wez Furlong and Sara Golemon for answering
questions about the streams layer, Pierre-Alain Joye for providing some insights
in the inner workings of the GD library, and less specifically the PEAR commu-
nity for their support and dedication to a great repository of usable PEAR com-
ponents. Some sections in this book were contributed by co-authors; Georg
Richter contributed the MySQLi section of the database chapter, and Zeev
Suraski added the section on Zend’s Performance Suite.
We would also like to thank Mark L. Taub and the editorial team of Pear-
son PTR for the things they are good at doing: organizing, planning, and mar-
keting this book, and making sure everything fits together. Thanks to Janet
Valade, for helpful developmental editing support, and our project editor
Kristy Hart, who helped us wrap up the book under pressure and put the final
touches on it.
Enjoy!
Andi, Stig, and Derick
