Review the differences between an abstract class and a base class. Review PHP constants.

Base Class

A base class creates consistent reusable code. When you extend a class the new subclass inherits all methods from the parent class.

Abstract Class

An provides a template for inheriting base class methods. Abstract classes cannot be instantiated

Interface

An interface provides methods but does not define how to use the methods.

PHP Constants
