Beginning PHP 4 [Illustriert] [Englisch] [Taschenbuch]

Beginning PHP4 offers an almost ideal introductory tutorial to one of today's hottest scripting languages. This book is really all the novice needs to start building dynamic Web sites powered by PHP4, but old hands at programming will also find valuable information inside it.

PHP, of course, is introduced in the book, but there is also an approachable and effective introduction to programming in general. The conscientious tutorial on basic concepts like variables, keywords and flow control will give even beginners an understanding of the basics of writing programs. PHP, it turns out, is not only a great way to generate HTML dynamically, it's a very marketable skill. Web fundamentals like HTTP, HTML form variables, and managing session information using no less than four different techniques are explained thoroughly and effectively. You also find out how to install PHP and other tools on your system, with the assistance of plenty of screen shots.

That's not to say that this book will cramp the style of more experienced developers. Some chapters delve into such important and advanced topics as database programming (with MySQL) and PHP's support for XML. One standout section demystifies the new support for objects and classes in PHP4. Basic topics like managing files and directories on the server, plus graphics processing, are addressed, of course, and a nifty sample program shows you how to build a Web-based text editor. Except for the final case study, a "URL directory manager" (akin to Yahoo) that is rather specialised, the examples are spot on, illustrating everyday programming tasks. You will also learn to generate e-mail with PHP, certainly a valuable skill to have.

The appendix lists several hundred PHP functions in over 50 pages--a handy and useful feature. In all, Beginning PHP4 provides a strong choice for learning about one of today's most powerful and easy-to-use scripting languages. It is concise, fast-moving and thoroughly approachable. --Richard Dragan

PHP is a server-side scripting language. It is an open source, cross platform technology (NT, Linux, UNIX), rapidly gaining popularity as a scripting language for people running dynamic websites. Using practical examples and a step by step approach, this book explains how to develop web applications using PHP.

PHP is a server-side scripting language. It is an open source, cross platform technology (NT, Linux, UNIX), rapidly gaining popularity as a scripting language for people running dynamic websites. On the Linux platform, PHP provides the most reliable and complete equivalent to ASP. Its cross-platform nature makes it an attractive alternative to ASP in mixed development environments. PHP is compatible with all popular Web servers, and can be integrated directly into the Apache server - the most popular Web server on the Internet. One of its major selling points over Perl, JavaScript and other scripting languages is that PHP has a built-in database integration layer and seamless IP connectivity, with LDAP, TCP and IMAP mail interfaces. Using practical examples and a step by step approach, this book explains how to develop web applications using PHP.

This book assumes some familiarity with HTML and the mechanics of the web, but is for people new to PHP who want to start developing web applications. This includes HTML users, ASP and ColdFusion developers looking to learn a new platform and web development managers wanting to move development to Linux.

PHP is a rapidly growing Web technology which enables web designers to build dynamic, interactive web applications, incorporating information from a host of databases, and including features such as e-mail integration and dynamically generated images. PHP4 added tons of features to make web application development even easier, and this book will show you how to make the most of the language's powerful capabilities.
 
This book is a complete tutorial in PHP's language features and functionality, beginning with the basics and building up to the design and construction of complex data-driven websites. Fully working examples in the book include a directory-style web search engine, a mailing list management system, a web-based file editor, and a graphical online shopping mall guidebook.
 
Who is this book for?
 
Anybody who knows HTML can use this book. If you've done any programming, that will be useful, but it's not a requirement. You can run all of the code on either a Windows(r) or UNIX(r) (e.g. Linux(r)) system, and the book explains how to set up a web server and database in both of these environments.
