Not true. With apache, QUERY_STRING will always be set; however, with
other web server software (ie. MS IIS) it will never be set unless you
have done so yourself.
Therefore, to be more portable, you may want to do something more like this:
if(isset($_GET) && is_array($_GET) && count($_GET)){
header("HTTP/1.0 404 Not Found");
echo <<< HTML
<html>
<head>
<title>404 Not Found</title>
</head>
<body>
<h1>Not Found</h1>
The requested URL was not found on this server.
</body>
</html>
HTML;
exit;
}
