Получить REDIRECT_STATUS с ошибкой_страницы

С помощью .htaccess а также ErrorDocument 404 /error.php, если доступ неверный URL, например: http://example/css/invalid-file.css:

<?php
echo 'REDIRECT_STATUS: ', $_SERVER['REDIRECT_STATUS'], PHP_EOL,
'REDIRECT_URL: ', $_SERVER['REDIRECT_URL'], PHP_EOL,
'REDIRECT_REQUEST_METHOD: ', $_SERVER['REDIRECT_REQUEST_METHOD'];

Выход:

REDIRECT_STATUS: 404
REDIRECT_URL: /css/invalid-file.css
REDIRECT_REQUEST_METHOD: GET

Но в Nginx использую error_page 404 /error.php; это не работает, результат в Nginx:

REDIRECT_STATUS: 200
REDIRECT_URL:
REDIRECT_REQUEST_METHOD:

Примечание. REDIRECT_URL и REDIRECT_REQUEST_METHOD не определены

Как установить переменные $_SERVER[REDIRECT_STATUS], $_SERVER[REDIRECT_REQUEST_METHOD] а также $_SERVER[REDIRECT_URL] с помощью Ngnix?
