Introduction

In this chapter, we will consider recipes that take advantage of the object-oriented programming (OOP) capabilities available in PHP 7.0, 7.1, and above. Most of the OOP functionality available in PHP 7.x is also available in PHP 5.6. A new feature introduced in PHP 7 is support for anonymous classes. In PHP 7.1, you can modify the visibility of class constants.

Note

Another radically new feature is the ability to catch certain types of error. This is discussed in greater detail in Chapter 13, Best Practices, Testing, and Debugging.
