Create a new variable name $booleanTwo. Set $booleanTwo equal to the result of comparing the variable $a as IDENTICAL to the string "5".

This is the Task^^

Hi there. :)

You need to compare the variable $a as identical (===) to the string "5" instead of equal (==), like so:

      $booleanTwo = ($a === $b);

And compare it to a string (not a variable) to pass the task, like so:

      $booleanTwo = ($a === "5");

You can remove variable $b from your code.

The difference between "==" (equal) and "===" (identical)

If you'd apply a var_dump on $booleanTwo, it would output bool(false). This is because variable $a is an integer, which is being compared to a string - in other words, the two entries are not IDENTICAL, because, even though the operands hold the same value, they are not from the same type (integer & string).

The integer and the string are EQUAL though (they're both 5 - the value is the same), so if you would remove one "=" (to make the comparison 'equal'), the var_dump would output bool(true). "==" does not check the type of the operands - only the value of the operands has to be the same for the comparison to be considered 'true'.

I hope you understand now. Good luck! ??

You need 3 = signs. $booleanTwo = ($a === $b);
