Nope. Unless you name it that way.

The default 'session.name' is PHPSESSID, which you can normally will NOT
find in $_SESSION, but in one of the $_REQUEST arrays (and thus obviously
in $_REQUEST). $_COOKIE['PHPSESSID'] _if_ the session works with cookies,
optionally in the $_POST or $_GET array in case of a transparant session
id (which is not recommandable).

If you choose another name for a session, this should be done with
session_name('custom_name_of_session') BEFORE the call to session_start():
