  * Function is similar to is_logged_in() function. If user is logged in, function

- * and $PHP_SELF in session and returns false. POST information is saved in
- * 'session_expired_post' variable, PHP_SELF is saved in 'session_expired_location'.
+ * and PAGE_NAME in session and returns false. POST information is saved in

  *
  * Script that uses this function instead of is_logged_in() function, must handle user
  * level messages.
