Well, I would suggest just using a “SESSION” variable. You would log in on your index.php page.
The code there will check if you are allowed in or not. If you are allowed in, then a SESSION variable
would be set. The first two lines in the premium.php page would check to see if the variable is set.
If not, it would redirect to the “You Are Not Allowed Here” page… If the variable is set, then, it let’s you in.
This is a common way to handle this. If someone types in the www.yourdomain.com/premium.php , then,
it just says your are not allowed there…

Is that what you want?
