Description:
------------
I realized it when i try someting about my web-based game, when you set
an integer NULL, it is same with 0 and ''.
Reproduce code:
---------------
<?php
$x = NULL;
if($x == 0) echo 'UPPS 1<br>';
if($x == '') echo 'UPPS 2<br>';
if($x === '') echo 'UPPS 3<br>';
?>
Expected result:
----------------
//output
Actual result:
--------------
//output
UPPS 1
UPPS 2
