This post describes how to compare variables that have integers using PHP.

To properly compare variables in PHP, we are taking a look at the intval function. If you try to compare variables without this function, you can run into troubles, such as your script returning that they are NOT the same.

<?php
$a=5;
$b='5';
if (intval($a)==intval($b)){
echo 'it's the same';
}
?>
