I am not sure what this problem is asking us to do. Written in a confusing way.
Not sure what is being asked in question 2
<?php $a = "5"; $isBoolean = true; $string = "5"; var_dump ($a === $string); $isIdentical = true; //Place your code below this comment ?>
the challenge is asking to assign the comparison to the variable $isIdentical.
So $isIdentical will then be comparing the integer 5 assign $a to the string value of '5', which with a strict comparison it should return false as its not the same type.
$isBoolean = true; $isIdentical = $a === '5';
Hope this helps
