error message unclear
need explanation of error message I have the following code: $a = 5; $isBoolean = true; $isIdentical; $isIdentical = var_dump($a === "5"); and get an error message saying "do not see variable $isIdentical" I am not sure why.
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
