PHP Objects, Patterns, and Practice THIRD EDITION

Dear Reader,

Over the past decade, PHP has embraced the object-oriented revolution. The

language itself, the developers who work with it, and the applications they build,

all increasingly share a focus on objects and object-oriented design. Another

movement, separate but related, has taken root as well. That is the use of tools

and techniques that help to ensure the success of projects, the efficacy of teams,

and the quality of code.

You’ll begin with an overview of PHP's object-oriented features, introducing

key topics like class declaration, object instantiation, inheritance, and method

and property encapsulation. You'll also learn about advanced topics including

static methods and properties, abstract classes, interfaces, exception handling,

object cloning, namespaces, closures and more.

The next part of this book is devoted to design patterns, a vocabulary for

applying elegant solutions to common problems in software development. You’ll

learn about pattern concepts and discover how to implement several key pat￾terns in your PHP applications. You’ll also find chapters on enterprise and data￾base patterns.

In the last section of this book, you will find practices and tools for managing

your codebase and for collaborating with others in development. These include

Phing, PHPUnit, phpDocumentor, PEAR, and Subversion. You’ll also learn how

to use Continuous Integration, a system that brings all these tools together and

automates them.

I wrote PHP Objects, Patterns, and Practice to provide the kind of overview of

code design and project practice I wish had been available when I first started to

develop serious PHP applications. I hope this book inspires pleasure in coding and

teaches you to build systems that are elegant in both design and management.
