Geocode don't work properly on a server

Question

I'm working on an web service in php, the service can invoke from a client who ask some latitude and longitude the service via query get the address from a database and use the google api:

$geocode=file_get_contents("https://maps.google.com/maps/api/geocode/json?address=".$row."&components=country:IT&sensor=true");

After that the service scrap the contents and gets the latitude and longitude

$lat = $address->results[0]->geometry->location->lat;
$lng = $address->results[0]->geometry->location->lng;

the problem is the lat and lng are wrong but if I try the address from a browser i get che correct lat and lng.

For example this is what i get from "http://maps.google.com/maps/api/geocode/json?address=Via%20Corno%20di%20Cavento,%20Milan,%20Metropolita&components=country:IT&sensor=false%22"

{
   "results" : [
      {

            },
            {

               "types" : [ "locality", "political" ]
            },
            {

               },
               "southwest" : {
                  "lat" : 45.47025660000001,

         "types" : [ "route" ]
      }
   ],
   "status" : "OK"
}

And this is what i got if i run that query from the php service:

"{
   "results" : [
         {
                  "address_components" : [
