Answer 1

I think you'll need country verification by IP, some database that maps IP addresses to cities/countries/providers, and then from it check the IP of user that is viewing the page with the database.

For php there is GeoIP extension, which would help you find the country. And then you would be able to check if that is the needed county and execute your desired code.
