Damn, you guys make my head blow.

Here is my try:

PHP Code:


			
$a = 1;
$b = 2;

$a += $b;
$b = $a - $b;
$a -= $b;
echo '$b = ' . $b . '<br />';
echo '$a = ' . $a;

And another one, think its quite smooth

PHP Code:


			


$a = 1;
$b = 2;
if($b = $a && $a = $b)echo '$b = ' . $b .'<br />$a = ' . $a;
