I got the question which is I already set the variable boolean two as a string "5", then compare with the variable $a which is number 5, which should return as false but it reply with task 1 is not passing? Have no idea what is going on. Thanks for help in advanced.
<?php
$a = 5;
//Place your code below this comment
$booleanOne = true;
$booleanTwo = "5"
var_dump($booleanOne);
var_dump($a === $booleanTwo);
?>

$booleanTwo = $a === '5';

8,236 PointsYea, you can compare it like that too. But that won't let you pass the challenge as it is asking "Set $booleanTwo equal to the result of comparing the variable $a as IDENTICAL to the string "5"

2,924 PointsThank you so much, but i still wondering since i did declare the $booleanTwo as a string (5), then why dont just compare like what i did ($a === $booleanTwo)? Because $a is a number and $booleanTwo is a String "5", it should be correct? Thank you in advanced.
