Object-Oriented Programming Inheritance

Inherit______nce is ______ concept of ______ccessing properties & methods of one cl______ss from ______nother cl______ss.

To define a (child) class that inherits (derives) from another (parent) class, you use the ______ keyword.

The parent class is also called a ______ class or super class.

One of the most important feature of inheritance in OOP is that it facilitates ______ reusability.

Inheritance in PHP is of 3 types: single, multiple & ______ inheritance.

What is the primary purpose of method overriding in OOP?

What happens when an object of the parent class invokes a method that has been overridden by a child class?

What determines which method (overridden or overriding) is called by PHP?

What is the term for the method in the parent class that is overridden by a child class?

What happens when an object of the child class invokes a method that has been overridden?

Inheritance is a concept that allows one class to access properties and methods of another class.

A child class inherits (derives) from a parent class using the extends keyword.
This enables the child class to inherit all public and protected properties and methods from the parent class.

A child class can have its own properties and methods in addition to the inherited ones.
The parent class is also known as a base class or super class.
The child class is also known as a derived class or a subclass.

Inheritance facilitates code reusability, saving time and effort while promoting clean code.

There are three types of inheritance in PHP: single, multiple, and multi-level inheritance.

Understanding inheritance is crucial for grasping the fundamental principles of object-oriented programming and its real-world applications.

Method overriding allows a child class to provide a specific implementation of a method already provided by its parent class.
The parent class method is called the overridden method, while the child class method is known as the overriding method.
The overriding method's code replaces the code in the overridden method.
PHP determines which method to call (overridden or overriding) based on the object used to invoke the method.

If an object of the parent class invokes the method, PHP executes the overridden method.
If an object of the child class invokes the method, PHP executes the overriding method.
