Because that wouldn't work :)
This variable may contain stuff like "nl,en-us;q=0.7,en;q=0.3". You'll
need to do something with this variable first to use
array_key_exists (or as you do, isset). That said, I agree that
strstr() might not be the best solution.
An other note, Dotan: shouldn't $_HTTP_ACCEPT_LANGUAGE actually be
$_SERVER['HTTP_ACCEPT_LANGUAGE']?
