That's clear, thanks. In nginx terms, it's an internal rewrite.

Your nginx will have some way to cause your index.php to be
processed. Maybe it is proxy_pass to a php-enabled web server; maybe it
is fastcgi_pass to a fastcgi server, maybe it is something else.

If you do something like

  location = /information { rewrite ^ /index.php?x=information; }
  location = /index.php {
    fastcgi_pass ...;
    fastcgi_param SCRIPT_FILENAME $document_root$uri;
    fastcgi_param QUERY_STRING $query_string;
  }

then you could instead omit the rewrite, and just do something like

  location = /information {
    fastcgi_pass ...;
    fastcgi_param SCRIPT_FILENAME $document_root/index.php;
    fastcgi_param QUERY_STRING x=information;
  }

directly.
