The above would not have the intended effect. My boolean maths is extremely
rusty but I think it is equivalent to saying:
if (!($_GET['sc'] == 2 AND $_GET['sc'] == 8))
Which means your code above is *always* TRUE, so do foo is always executed!
In any case you can easily test it by mentally plugging in values 1 to 8 for
$_GET['sc'] and evaluating it for yourself.
