地理编码无法在服务器上正常运行

Question

我正在处理php中的Web服务，该服务可以从客户端调用，该服务器通过查询询问服务的某些纬度和经度，从数据库获取地址并使用google api：

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

之后，服务会废弃内容并获取经度和纬度

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

问题是lat和lng是错误的但如果我从浏览器尝试地址我得到正确的lat和lng。

例如，这是我从＆＃34; http://maps.google.com/maps/api/geocode/json?address=Via%20Corno%20di%20Cavento,%20Milan,%20Metropolita&components=country:IT&sensor=false%22＆＃34;

获得的

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

如果我从php服务运行该查询，这就是我得到的：
