Как получить страну по определенному IP?

latlng = new google.maps.LatLng(google.loader.ClientLocation.latitude, google.loader.ClientLocation.longitude);
location = "IP location: " + getFormattedLocation();
document.getElementById("location").innerHTML = location;

  <?php  $ip = $_SERVER['REMOTE_ADDR'];
    $json = file_get_contents("http://api.easyjquery.com/ips/?ip=".$ip."&full=true");
    $json = json_decode($json,true);
    $timezone = $json[localTimeZone];?>

$ curl ipinfo.io/8.8.8.8
{
  "ip": "8.8.8.8",
  "hostname": "google-public-dns-a.google.com",
  "loc": "37.385999999999996,-122.0838",
  "org": "AS15169 Google Inc.",
  "city": "Mountain View",
  "region": "CA",
  "country": "US",
  "phone": 650
}

$ curl ipinfo.io/8.8.8.8/country
US

function ip_details($ip) {
    $json = file_get_contents("http://ipinfo.io/{$ip}");
    $details = json_decode($json);
    return $details;
}

$details = ip_details("8.8.8.8");

echo $details->city;     // => Mountain View
echo $details->country;  // => US
echo $details->org;      // => AS15169 Google Inc.
echo $details->hostname; // => google-public-dns-a.google.com
