$x = $a ^ $b;
if (($a ^ $x) != $b)
  die("that should not happen...");

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

_Make sure_ you post complete & short script.

[yohgaki@dev DEV]$ cat a.php 
<?php
$a = 1;
$b = 2;

$x = ($a ^ $b);
var_dump($x);
var_dump($b);
if (($a ^ $x) != $b) {
  echo "NG";
}
?>


[yohgaki@dev DEV]$ php a.php
int(3)
int(2)
