Try:

if ($myzone!='here' && $myzone!='there' && $myzone!='where') die;


Or, using De Morgan's Laws (boolean algebra law concerning the
relationship between NOT, AND and OR) you could alternatively use:

if (!( $myzone=='here' || $myzone=='there' || $myzone=='where' )) die;


Or, to make your code read a bit more sanely (but might actually run
slower!):

$allowed_states = array('here', 'there', 'where');
if (!in_array($myzone, $allowed_states)) die;
