Programming PHP

Kevin Tatroe has been a Macintosh and Unix programmer for ten years. Being lazy, he's attracted to languages and frameworks that do much of the work for you, such as the AppleScript, Perl, and PHP languages and the WebObjects and Cocoa programming environments. Kevin, his wife Jenn, his son Hadden, and two cats live on the edge of the rural plains of Colorado, just far away enough from the mountains to avoid the worst snowfall, and just close enough to avoid tornadoes. The house is filled with LEGO creations, action figures, and other toys. Rasmus Lerdorf started the PHP Project back in 1995 and has been actively involved in PHP development ever since. Also involved in a number of other Open Source projects, Rasmus is a longtime Apache contributor and foundation member. He is the author of the first edition of the PHP Pocket Reference, and the co-author of Programming PHP. Peter MacIntyre lives and works in Charlottetown, Prince Edward Island, Canada. He has over 16 years of experience in the information technology industry, primarily in the area of software development. Peter's technical skill set includes several client/server tools and relational database systems such as PHP, PowerBuilder, Visual Basic, Active Server Pages, and CA-Visual Objects. Peter is certified by ZEND Corporation on PHP 4.x and has contributed writing material for Using Visual Objects (Que Corp.), Using PowerBuilder 5 (Que Corp.), ASP.NET Bible (Wiley Pub.), and Web Warrior Survey on Web Development Languages (Course Technology). Peter is also currently a contributing editor and author to the on-line and in-print magazine called php|architect (www.phparch.com). He has also spoken several times at North American and International computer conferences including CA-World in New Orleans, USA; CA-TechniCon in Cologne, Germany; and CA-Expo in Melbourne, Australia.
