What’s New in This Edition
Since the first edition of this book, PHP has consolidated its position as one of the best options for Web development. PHP, in common with any popular open-source project, is a fast-moving target. In this edition we have extensively checked and updated the examples and tutorials. Where new features have appeared, we have extended our coverage. We have significantly revised our coverage of objects, XML, and SQL to take account of changes in PHP 5.
In addition to reviewing and extending existing material, we have added coverage for PEAR, an entirely new chapter on advanced objects, and a set of libraries for managing larger projects.
