How do I limit which countries can view my website ( PHP )

Question

In there an easy way to do this in PHP. I want to make sure that only web requests from certain countries are able to access my website.

Any ideas?

Answer 1

if you use the answer of Ben Dowling and the code doesn't work, try this:

if (!in_array(substr($country, 0, 2), $allowed_countries)) {

instead of:

if(!in_array($country, $allowed_countries)) {
