# session_unregister

(PHP 4, PHP 5)

session_unregister — Unregister a global variable from the current session

### Описание

bool session_unregister ( string `$name` )

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

Внимание

This function has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 6.0.0. Relying on this feature is highly discouraged.

### 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().
