This mess will *ALWAYS* evaluate to TRUE, because the $value is ALWAYS
only one value, and thus the other 99 values are going to evaluate to
TRUE and you have || between them...

So you have:

TRUE || TRUE || TRUE || FALSE || TRUE || TRUE ... || TRUE

which is always gonna boil down to TRUE.

You wanted && instead of ||

Actually, it would be MUCH better imho to set up a couple arrays like:

$states = array('Alabama', 'Alaska', ...);
$sts = array('AL', 'AK', ...);

if (!isset($states[$value]) && !isset($sts[$value])){
  echo "Bad Dog!";
}

YMMV
