Aim: Demonstrate Single Inheritance in PHP

Program

<?php
// Parent class
class Animal {
    public function sound() {
        echo "Animals make sounds.";
    }
}

// Child class (single inheritance)
class Dog extends Animal {
    public function sound() {
        echo "Dog barks.";
    }
}

// Object creation
$dog = new Dog();

// Calling method
$dog->sound();
?>


  • Animal is the parent (base) class.

  • Dog is the child (derived) class.

  • Dog inherits the Animal class using extends.

  • This demonstrates single inheritance (one parent → one child).
