Function: session_unregister (PHP 4, PHP 5) session_unregister -- Unregister a global variable from the current sessionDescriptionbool session_unregister ( string name )session_unregister() unregisters the global variable named name from the current session. This function returns TRUE when the variable is successfully unregistered from the session. Note: 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. Caution 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. Caution If you are using $_SESSION (or $HTTP_SESSION_VARS ), do not use session_register() , session_is_registered() and session_unregister() . Related Function(s) |
