This function obtain the IP address of the visitor.

         function get_visitor_ip(){
		$ipaddress = '';
		if (getenv('HTTP_CLIENT_IP'))
			$ipaddress = getenv('HTTP_CLIENT_IP');
		else if(getenv('HTTP_X_FORWARDED_FOR'))
			$ipaddress = getenv('HTTP_X_FORWARDED_FOR');
		else if(getenv('HTTP_X_FORWARDED'))
			$ipaddress = getenv('HTTP_X_FORWARDED');
		else if(getenv('HTTP_FORWARDED_FOR'))
			$ipaddress = getenv('HTTP_FORWARDED_FOR');
		else if(getenv('HTTP_FORWARDED'))
			$ipaddress = getenv('HTTP_FORWARDED');
		else if(getenv('REMOTE_ADDR'))
			$ipaddress = getenv('REMOTE_ADDR');
			$ipaddress = 'UNKNOWN';

        $ipaddress= get_visitor_ip(); // Store the IP address

     $data =  @json_decode($response);
     $country = $data->geoplugin_countryName;
     $state = $data->geoplugin_region;
     $latitude = $data->geoplugin_latitude; 
     $longitude = $data->geoplugin_longitude; 
     $currency_symbol =  $data->geoplugin_currencySymbol;
