Check if User Has Authenticated

[Henry Hartley]

I've got a web site that has a mix of public and private sections.
When you first come to the site, the final option on the menu is
"Private" which forces an authentication and then gives you an
expanded menu that includes all the private sections of the site.
What I'd like to do is give users the proper menu ("public only" or
"public and private") depending on whether they have authenticated
with the site.

I thought of just checking for $_SERVER["REMOTE_USE R"] or
$_SERVER["PHP_AUTH_U SER"] but if you are on a public page, those don't
exist whether or not you have authenticated with the private sections.
I was hoping not to have to deal with sessions or cookies but is that
the only option I have? Or is there some value somewhere that will
tell me that a user has authenticated and that is available (to PHP)
even in the public areas?

You will get $_SERVER["PHP_AUTH_U SER"] in your public pages once the user
has entered his username/password. The browser doesn't just send the
authentication info to the page which generated the 401 Unauthorized
response. It sends it for all files at the same directory level and below.
