This wiki shows how to get the geolocation info of the client using another server API It could be write also as extension but there are a lots of APIs that change the below code So, I wrote the below code that works for one of them (using

Add the file Geolocation.php in protected/components

class Geolocation {

    public static $ipaddress = null;
    public static $clientInfoLocation = null;

    public static function get_client_ip() {
        if (self::$ipaddress == null) {
            if (isset($_SERVER['HTTP_CLIENT_IP']))
                $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
            else if (isset($_SERVER['HTTP_X_FORWARDED_FOR']))
                $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
            else if (isset($_SERVER['HTTP_X_FORWARDED']))
                $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
            else if (isset($_SERVER['HTTP_FORWARDED_FOR']))
                $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
            else if (isset($_SERVER['HTTP_FORWARDED']))
                $ipaddress = $_SERVER['HTTP_FORWARDED'];
            else if (isset($_SERVER['REMOTE_ADDR']))
                $ipaddress = $_SERVER['REMOTE_ADDR'];
                $ipaddress = '';
        return self::$ipaddress;

    public static function getClientInfoLocation() {
        if (self::$clientInfoLocation == null)
            self::$clientInfoLocation = (unserialize(file_get_contents('' . self::get_client_ip())));
        return self::$clientInfoLocation;

    public static function getClientCountry() {
        $dt = self::getClientInfoLocation();
        return strtolower($dt['geoplugin_countryName']);

    public static function getClientLangCode() {
        $dt = self::getClientInfoLocation();
        return strtolower($dt['geoplugin_countryCode']);


Now, In any controller you chould use Geolocation::getClientCountry() or Geolocation::getClientLangCode()
