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

Php file :

<?php

class intro

{

              var $i;

              function f1()    {}

              function f2()    {}

}

class intro_1 extends intro

{

              var $j,$k;

              function f3()    {}

              function f4()    {}

}

echo class_exists('intro');         //returns true if class is exist

var_dump(get_declared_classes());       //returns an array of all the class are define & declared in php including classes name

var_dump(get_class_methods('intro_1'));      //returns an array of methods in class intro_1

var_dump(get_class_methods('Exception'));     //returns an array of methods in class Exception

var_dump(get_class_vars('intro_1'));     //returns parent class of given class intro_1 if it is exists

var_dump(get_parent_class('intro_1'));      //reurns parent class of given class if it exist

var_dump(get_object_vars($ob));    //retuns an array of parameter / variables for given object

?>
