Ah, I see, so would something like this work:

$alias = "James";
$password = "MyPassword";

function check_alias_password($alias_arg, $password_arg)
    {
        if ((!$alias_arg) || (!$password_arg)) {
            header("Location: login.php");
            exit;
        }
    }

check_alias_password($alias, $password);

or

function check_alias_password()
    global $alias, $password;
    {
        if ((!$alias) || (!$password)) {
            header("Location: login.php");
            exit;
        }
    }

check_alias_password();

work? Or would the last example need to be globals (variables) instead of
global?

It does, and your help is greatly appreciated ;)
