  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).

  Aim : Demonstrate a simple abstract class Program <?php // Abstract class abstract class Shape { abstract public function calculateArea ( ); } // Child class class Rectangle extends Shape { private $length ; private $width ; public function __construct ( $l , $w ) { $this ->length = $l ; $this ->width = $w ; } public function calculateArea ( ) { return $this ->length * $this ->width; } } // Object creation $rect = new Rectangle ( 10 , 5 ); // Display output echo "Area of Rectangle: " . $rect -> calculateArea (); ?> abstract class cannot be instantiated directly. Abstract methods must be implemented in the child class. Demonstrates abstraction and inheritance .

  Aim 1(a): Check if the given string is in lowercase Program <?php $string = "hello world" ; if ( $string === strtolower ( $string )) { echo "The given string is in lowercase." ; } else { echo "The given string is NOT in lowercase." ; } ?> strtolower() converts a string to lowercase. If the original string and lowercase string are the same, it means the string is already in lowercase. Aim 1(b): Replace a given word from the given string Program <?php $string = "PHP is a powerful scripting language" ; $search = "powerful" ; $replace = "popular" ; $newString = str_replace ( $search , $replace , $string ); echo "Original String: " . $string . "<br>" ; echo "Modified String: " . $newString ; ?> str_replace() replaces a word or part of a string with another word. The function does not change the original string; it returns a new o...
