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

?>

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

Hi there, Neven Shtiliyanov! Looks like you're off to a good start. However, you were not meant to alter the first line. The first line should remain as $a + 5;. Your $isBoolean looks fine.

The next thing it's asking for is a variable that holds the result of asking if $a, which should still be the integer 5 is identical to the string "5". You will not need a var_dump.

For $isIdentical it's looking for:

$isIdentical = $a === "5";

This, however, assumes that you have not altered the first line of the challenge.

Hope this helps! :sparkles:
