session_unregister() unregisters the global variable named name from the current session.

Внимание

Данная функция была помечена УСТАРЕВШЕЙ начиная с версии PHP 5.3.0 и была УДАЛЕНА в версии PHP 5.4.0.

Список параметров

name: The variable name.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

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.

Предостережение

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.

Предостережение

If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(), session_is_registered() and session_unregister().

If globals is on, you'll have to unset the $_SESSION[varname] as well as the $varname.



Like:



unset($_SESSION[varname]);

unset($varname);

as a side note you must have session_start() set inorder to actually unregister the session varibles.
