PHP: XOR swap

The XOR swap lets you swap the value of integer variables without using a temporary variable, it's also slightly faster.
PHP:
-
$x ^= $y;
-
$y ^= $x;
-
$x ^= $y;
I can't actually think of a good reason Why you'd want to use this in PHP since memory isn't normally a big issue, however it might be good for showing off
