How do I Identify a Visitor's Country?

When visitors click on my links, I want to check which country they're in and redirect them to a destination based on their country. I know how to do the redirect, but I don't know how to identify the country.

Can anyone help me, please?

I conducted a bit of research and discovered that I have to download some kind of IP database. Can anyone explain what I have to do in more detail? I will appreciate it very much.

 

Hello Masterful,
As you have noted this is done via IP addresses. First you need to get the IP address of the vistor via a php statement such as $ip=$_SERVER['REMOTE_ADDR']; Then you need a database such Geoip db (which could be found at maxmind.com/app/geoip_country

Please have a look at :
