Welcome to Part 06 ofObject-Oriented Programming Using PHP in Urdu 2017 by Perfect Web Solutions.
In this Video Tutorial we will learn about Abstraction in PHP and will see how to create Abstract Classes and Methods and why we use Abstraction in OOP concepts.
PHP 5 introduces abstract classes and methods. Classes defined as abstract may not be instantiated, and any class that contains at least one abstract method must also be abstract. Methods defined as abstract simply declare the method’s signature – they cannot define the implementation.
