Nginx, deny all works strangely. What to do?

Question

Nginx

Hello fellow people. When such lines are entered into the nginx config, access to all files except .php is restricted. How can I fix it?

location /engine/ {
  deny all;
}

Answer 1

The regular prefix location has a lower precedence than regular expression locations.
Raise the priority of the deny rule with the ^~ modifier:

location ^~ /engine/ {
    deny all;
}

Answer 2

Apparently, add a forbidding directive to another location - which processes php files.
