根据国家/地区将用户重定向到子域（au、nz 等）的最佳方法是什么？

Question

I have a php based web application in which I want to redirect user to sub domain based on their country such as nz, au, in etc.

What is the best way to do that?

Htaccess? PHP? JavaScript?

How can I do with the above options?

Or you guys can suggest any other way as well!

Answer 1

Please! check this out:

geoPlugin

and there is more such way which is helpful.

Edit

Reference:

1. geoPlugin class for PHP
2. list of geo country codes

Code:

<?php

$meta = unserialize(file_get_contents('http://www.geoplugin.net/php.gp? 
ip='.$_SERVER['REMOTE_ADDR']));

if($meta['geoplugin_countryCode']=='IT') 
{
}
?>

PHP Geolocation Web Service

Answer 2

Something like this (Pseudo code!):

RewriteEngine on
RewriteCond %{ENV:GEOIP_COUNTRY_CODE}
RewriteRule ^(.*)$ https://example.com/$1 [L]
