Build server-side applications more efficiently--and improve your PHP programming skills in the process--by learning how to use design patterns in your code. This book shows you how to apply several object-oriented patterns through simple examples, and demonstrates many of them in full-fledged working applications.

Learn how these reusable patterns help you solve complex problems, organize object-oriented code, and revise a big project by only changing small parts. With Learning PHP Design Patterns, you'll learn how to adopt a more sophisticated programming style and dramatically reduce development time.

• Learn design pattern concepts, including how to select patterns to handle specific problems
• Get an overview of object-oriented programming concepts such as composition, encapsulation, polymorphism, and inheritance
• Apply creational design patterns to create pages dynamically, using a factory method instead of direct instantiation
• Make changes to existing objects or structure without having to change the original code, using structural design patterns
• Use behavioral patterns to help objects work together to perform tasks
• Interact with MySQL, using behavioral patterns such as Proxy and Chain of Responsibility
• Explore ways to use PHP's built-in design pattern interfaces
