redirecting a user to a login page

[sws]

I have a page that requires a user to be logged in before they can view the page.

I have written code that loads the page if they are logged in. In my else statement I need to know how to redirect the user to my login page.

Can anybody please tell me how to do this ?

Thanks in advance.

Use:

header('Location: http://www.example.com/login.php');
exit;

You can't send any output to the browser before issuing the header().
