PHPSESSID vs session_id()

[Sleidia]

Hello,

I'just found out that:

when together,
session_start();
$user_ID = $PHPSESSID;
--> user_ID will be empty

when together,
session_start();
$user_ID = session_id();
--> user_ID will have a value

You have to use session_id() when you want to start the session and call the id in the same page.
* applied for Apache/php win32

Yes, if you configure PHP to disable register_globals, php does not copie the cookie var PHPSESSID to $PHPSESSID.

this way you can always do $_COOKIE["PHPSESSID"] instead of $PHPSESSID.
