Her main focus is in e-commerce, but she develops sites across numer- ous industries. She is currently a moderator at PHPBuilder.com, an online help center for PHP. She lives in Cincinnati, Ohio with her husband and two children, and looks forward to someday returning to Miami to get her Masters in Computer Science. Thanks to my husband and soul mate who continues to be supportive of everything I do, and who inspires me to always do a little better. Thanks to my children who make me understand the importance of looking outside the box and keeping my sense of humor, and for making me proud to be a mom. Also, thank you to Debra for always keeping us on track, and for having faith in us. Jason “goldbug” Gerner Jason currently spends his days working as a Web developer in Cincinnati and burns free time com- plaining about lack of support for Web standards and abusing XML. He can often be found lurking in the PHPBuilder.com discussion forums, waiting to chime in with nagging comments about CSS or code efficiency. Yann “Bunkermaster” Le Scouarnec Yann is the senior developer for Jolt Online Gaming, a British gaming company. He is a moderator at PHPBuilder.com and a developer of open source PHP software for the gaming community. He has also worked for major software corporations as a software quality expert. I thank all the innocent bystanders who got pushed around because of this project: Debra and Nancy, who were patient enough not to have homicidal thoughts; and my wife and kids, who barely saw me for six months. Jeremy “stolzyboy” Stolz Jeremy is a Web Developer at J&M Companies, Inc. (www.jmcompanies.com), a print company in Fargo, North Dakota. Jeremy is primarily a PHP/MySQL developer, but he has also worked with many other languages. When not working, he frequents the Internet and tries to keep his programming skills sharp and up to date. He is a contributor to and moderator at PHPBuilder.com. I’d like to thank my wife, my baby daughter, and the rest of my family for being patient with me while working on this project. 01_579665 ffirs.qxd 12/30/04 8:08 PM Page v www.it-ebooks.info Michael “BuzzLY” Glass Michael Glass has been a gladiator in the software/Web site development arena for more than eight years. He has more than ten years of commercial programming experience with a wide variety of tech- nologies, including PHP, Java, Lotus Domino, and Vignette StoryServer. He divides his time between computer programming, playing pool in the APA, and running his Web site at www.ultimatespin.com. You can usually find him slinking around on the PHPBuilder.com forums, where he is a moderator with the nickname BuzzLY. Thanks, Staci, for putting up with long and late hours at the computer. Elizabeth and Jason, it wouldn’t have been the same project without you two. And thanks to my code testers at www.ultimatespin.com: Spidon, Kaine, Garmy, Spidermanalf, Ping, Webhead, and FancyDan. You guys rock! To Donna and Gerry, who have influenced my life more than they can ever know, and who taught me the importance of finishing what you’ve started. 01_579665 ffirs.qxd 12/30/04 8:08 PM Page vi www.it-ebooks.info Credits Acquisitions Editor Debra Williams Cauley Development Editor Brian MacDonald Senior Production Editor Angela Smith Technical Editor Jason Gerner Copy Editor Kim Cofer Editorial Manager Mary Beth Wakefield Vice President & Executive Group Publisher Richard Swadley Vice President and Publisher Joseph B.
