How to redirect from main to internal?

Question

PHP

Good afternoon.
Please tell me how can I make a redirect from "/" to "/news" using PHP or NGINX, for example. At the same time, when visiting other pages, for example "/gallery", I would not be redirected to "/news".
Those. my main page is empty, I need it to be redirected to the module when visiting the main page.
How can this be implemented? Preferably with PHP.
Thanks in advance.

php.net/manual/ru/function.header.php

$path = parse_url($url, PHP_URL_PATH);
if (empty( $path ))
    header('Location: http://www.example.com/news');

Guys, it takes longer to ask such questions than to google.
header( 'Location: google.ru/search?q=redirect ' );
