session_is_registered
(PHP 4)
Description
session_is_registered() returns TRUE if there is a global variable with the name name registered in the current session.
蛁: If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use isset() to check a variable is registered in $_SESSION.
蛁砩
If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(), session_is_registered() and session_unregister().
