Why is simple PHP header authorization not working
$username = 'test';
$password = 'test';

If (!isset($_SERVER['PHP_AUTH_USER'])|| !isset($_SERVER ['PHP_AUTH_PW'])||
    ($_SERVER['PHP_AUTH_USER'] != $username) || ($_SERVER['PHP_AUTH_PW'] != $password)){

//send this if the user and pass arent correct

header('HTTP/1.1 401 Unauthorized');
header('WWW-Authenticate: Basic Realm= "mysite"');
exit('<h2> Go away Creep!!</h2> you need a username and password to enter this kingdom!!');
}
