My old solution before I found out about the abs function was this:

PHP Code:

function absolute_sub($i1, $i2) {
        # Ensure Absolute Value after Subtraction.
        if ($i1 == $i2)
                return 0;
        else if ($i1 > $i2)
                return $i1 - $i2;
        else
                return $i2 - $i1;
} 


Boy, did I feel stupid after I found out about abs.
