An intermediate-to-advanced users guide to PHP, the Web scripting language in use on over six million Web sites. An excellent companion book to the "PHP Visual QuickStart Guide." The book focuses specifically on real-life PHP projects, as determined by frequent PHP questions asked in newsgroups, e-mails, chat rooms, and Web sites.

PHP is a server-side, HTML-embedded scripting language. ItÕs frequently being used to replace the functionality created by Perl to write CGI scripts). Similar to both HTML and CGI, PHP is faster to program in and faster to execute than CGI. PHP was written specifically for Web site creation, unlike Perl, C, or Java. Companies such as Honda, Patagonia, and Zoom.com all have Web sites utilizing PHP. PHP Advanced for the World Wide Web: Visual QuickPro Guide consists of approximately fifteen chapters of step-by-step content, aimed at teaching specific topics in direct, focused segments. The scripts featured in this book are based on features and capabilities that current PHP users most frequently inquire about (e.g. sessions, authentication, and object-oriented programming). as well as detailing those technologies that will be more important in the future, such as XML and Wireless Access Protocols.

This is the eBook version of the printed book. If the print book includes a CD-ROM, this content is not included within the eBook version. Over the past three years PHP has evolved from being a niche language used to add dynamic functionality to small sites to a powerful tool making strong inroads into large-scale, business-critical Web systems. The rapid maturation of PHP has created a skeptical population of users from more traditional "enterprise" languages who question the readiness and ability of PHP to scale, as well as a large population of PHP developers without formal computer science backgrounds who have learned through the hands-on experimentation while developing small and midsize applications in PHP. While there are many books on learning PHP and developing small applications with it, there is a serious lack of information on "scaling" PHP for large-scale, business-critical systems. Schlossnagle's Advanced PHP Programming fills that void, demonstrating that PHP is ready for enterprise Web applications by showing the reader how to develop PHP-based applications for maximum performance, stability, and extensibility.

The best way to become acquainted with a subject is to write a book about it. —Benjamin Disraeli i. Background The purpose of this book is provide an introduction to using a server-side programming language to solve some kinds of computing problems that cannot be solved with a client-side language such as JavaScript. The language is PHP (originally created in 1994 by Danish/Icelandic programmer Rasmus Lerdorf as “Personal Home Page Tools” for dealing with his own web site). The PHP language does not have a formal specification, as C does, for example. It is developed and maintained by a User Group of volunteers and is, essentially, defined by the most recently available free download. Although this might seem to be a shaky foundation on which to make a commitment to learning a programming language, PHP has a very large world-wide base of users and applications, which ensures its role into the foreseeable future. This book should not be considered as a PHP reference source and it does not deal exhaustively even with those elements of the PHP language used in the book. (This should be considered a blessing by the casual programmer. ) If you need more information, there is a huge amount of information online about PHP. Hopefully, this book will help you filter this information to focus on solving typical science and engineering problems. An excellent online source for information about PHP is http://www. php. net/manual/en/index. php, maintained by the PHP 1 Documentation Group.
