PHP comparing

How am I suppose to equal these values if I'm not allowed to use var_dump()??

index.php 
<?php
$a = 5;
//Place your code below this comment
$isBoolean = true;
$isIdentical = "5"
  var_dump($a == $isIdentical);
?>

The instructions say to "assign the results to $isIdentical", you won't need to output anything. The results of a comparison can be assigned to a variable just like a simple value can (and the entire statement can go on one line).

And the instructions also say to compare for "identical (equal AND of the same type)", so remember to use the special identity comparison operator (hint: it has more characters than the simple equality operator).
