What This Book Covers
Chapter 1 introduces object-oriented programming and how it fits for PHP. Some benefits of functional programming over procedural programming are highlighted.
In Chapter 2 you learn to create objects and define their properties and methods. Details of classes, properties, and methods follow, along with the scope of methods. This chapter shows you the benefits of using interfaces and a few other basic OOP features in PHP to kick start your journey through OOPing in PHP.
Now that you have got
your basics done for OOP in PHP, Chapter 3 helps you to strengthen your base. It helps you to deal with more details and some advanced features. For example, you learn about class information functions, which allows
you to investigate details of any class. This chapter takes you through some handy object-oriented information functions, exception handling, iterators, and storing objects using serialization.
In Chapter 4 you learn some of the Design Patterns and how to implement them in PHP. These are an essential part of OOP and make your code more effective, more efficient, and easier to maintain. Sometimes we implement these design patterns in our code without knowing that these solutions are defined by design patterns. Proper usage of the correct pattern can make your code perform better; similarly using them improperly could make your code slower and less efficient.
