• Inheritance is feature in OOP where you can extend a class and create a completely new object.


• The new object keep all the functionality of the parent object from which it is extended or can override.

Example :

<?php
class Base
{
	function add()
	{
		echo " Base Class function </br>";
	}
}
Class Demo extends Base
{
	function subtract()
	{
		echo " Derived Function ";
	}
}
$obj=new Demo();
$obj->add();
$obj->subtract();
?>

Output :

Base Class function 
Derived Function
