Write a PHP script to demonstrate the introspection for examining class .(use function get_declared_classes() ,get_class_methods() and get_class_vars())||EasyCoding45

 In this Tutorial, we are going to learn how we can Write a PHP script to demonstrate the introspection for examining class .so we are going to  use functions like  get_declared_classes() ,get_class_methods() and get_class_vars() for the Above Question.

Program::--

<?php

class cylinder 

{

const pi=3.14;

public $ar=null;

public $vol=null;

function area($r,$h)

{

$this->ar=2*self::pi*$r*$h+2*self::pi*$r*$r;

echo "Area of Cylinder is :$this->ar<br> ";

}

function volume($r,$h)

{

$this->vol=2*self::pi*$r*$r;

echo "\nVolume of Cylinder is :$this->vol";

}

}

/*$obj=new cylinder();

$obj->area(25,14);

$obj->volume(25,14);

*/

echo "<br>Classes are :";

$classes=get_declared_classes();

print_r($classes);

echo "<br>Class methods are :<br>";

$methods=get_class_methods(cylinder);

print_r($methods);

echo "<br>Class variables are :<br>";

$var=get_class_vars(cylinder);

print_r($var);

?>

Note ::--

We are Using Print_r() method so we can print returned Array.

Output::--
