Примечания
Замечание: If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use unset() to unregister a session variable. Do not unset() $_SESSION itself as this will disable the special function of the $_SESSION superglobal.
This function does not unset the corresponding global variable for name , it only prevents the variable from being saved as part of the session. You must call unset() to remove the corresponding global variable.
If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(), session_is_registered() and session_unregister().
