Get Country of IP Address with PHP

I'm trying to put together a PHP script that I can query from any web browser and it returns the Country of the IP address that accessed the PHP script


There are various web APIs that will do this for you. Here's an example using http://ipinfo.io:

          $ip = $_SERVER['REMOTE_ADDR'];
$details = json_decode(file_get_contents("http://ipinfo.io/{$ip}"));
echo $details;

  

 Here's an example using http://www.geoplugin.net/json.gp

$ip = $_SERVER['REMOTE_ADDR'];
$details = json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip={$ip}"));
echo $details;
