How to deny access to a folder and files inside Nginx?

Question

Nginx

location / {
allow 123.456.789.1;
deny all;
}

Yes, it works, but if you access the internal files of the folder, then there are no restrictions, i.e. index.php will be executed.

Question: How to deny access to all folders on the server and files inside.

Answer 1

Obviously, the request does not fall into location / {, but somewhere like location ~ \.php$ {
You can move allow and deny directly into the server block.
