What will be the output of the following PHP code?

<?php
$string = "Hello Interview Mania. It's a knowledgeable website.";
print_r (explode(" ",$string));
?>

Array
(
    [0] => Hello
    [1] => Interview
    [2] => Mania.
    [3] => It's
    [4] => a
    [5] => knowledgeable
    [6] => website.

The explode() function breaks a string into an array.
