What is wrong with the code?

It seems right...

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

Hi Mika,

You don't have to pre-declare the boolean and identical variable. You have to assign $isIdentical with the equal sign. Try it like this!

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

$isBoolean = true;
$isIdentical = ($a === "5");

you need to asign the result of is $a identical to "5" and there is a missing equal after $isIdentical, and when you check is $a identical with "5" you need === (3 equal signs for identical).
