City/State by zip not working on webhost

[lovephp]

friend the following code fetches city state etc from google by zip or postcode which works fine on my localhost wamp server but when i try it online on my webhost nothing is showing, how can i fix it please?

 

        $search_code = urlencode($row['zip']);
        $url = 'http://maps.googleapis.com/maps/api/geocode/json?address=' . $search_code . '&sensor=false';
        $json = json_decode(file_get_contents($url));
        $lat = $json->results[0]->geometry->location->lat;
        $lng = $json->results[0]->geometry->location->lng;
        $address_url = 'http://maps.googleapis.com/maps/api/geocode/json?latlng=' . $lat . ',' . $lng . '&sensor=false';
        $address_json = json_decode(file_get_contents($address_url));
        $address_data = $address_json->results[0]->address_components;
        $street = str_replace('Dr', 'Drive', $address_data[1]->long_name);
        $town = $address_data[2]->long_name;
