var_dump doesn't return anything. See docs

Try your code in a workspace and add the last line:

<?php
$a = 5;
$isBoolean = true;
$isIdentical;
$isIdentical = var_dump($a === "5");
var_dump($isIdentical);

you'll see $isIdentical is assigned NULL

treehouse:~/workspace$ php index.php                                                                           
bool(false)                                                                                                    
NULL

So for the challenge eliminate var_dump and you'll pass
