Revised for PHP version 4, the new edition of Core PHP Programming is a comprehensive tutorial and reference to one of today's hottest scripting languages. Part tutorial and part reference, this book will get beginners started with PHP, as well as provide a convenient desktop resource for more experienced PHP developers. Early sections show what PHP is and how it works, with basic data types, flow control, and other topics you'll need to get started. But the heart of the book is a full reference to PHP 4 functions. Organised by topic, this text provides over 400 pages of reference to several hundred PHP calls, along with a description of what they do. Clearly organised and presented, this book will help you find what you need quickly (instead of relying on PHP's often cumbersome online help). In particular, readers will appreciate the coverage of database functions, including the separate calls for MySQL, ODBC, and Oracle. You'll also see what PHP can do with XML. The last part of the book reverts to tutorial mode, first with a section on algorithms that discusses ways to sort and search PHP arrays. Final sections look at some strategies you can use to integrate PHP into the software design process, in which the strategies of combining HTML content with dynamic PHP scripts are shown. There is also useful advice for increasing performance with PHP. (It would seem that upgrading to PHP 4 is a must, because the new version offers a real performance boost.)
