Google Maps API - 使用PHP检索城市和州

我目前正在使用Google Maps API来获取用户街道，街道号码和邮政编码的经度和纬度 .

我还想从Maps API结果中获取他们的城市和州 . 虽然XML文档格式奇怪，但我不确定我应该如何引用它（它与我 grab long和lat的方式不同） .

这就是我加载Maps API的方式：

$map_address = str_replace($address."+".$zip);
$map_api_url = "https://maps.googleapis.com/maps/api/geocode/json?address=".$map_address."&key=myKey";
$resp_json = file_get_contents($map_api_url);
$resp = json_decode($resp_json, true);

然后我得到了Long和Lat：

$lati = $resp['results'][0]['geometry']['location']['lat'];
$longi = $resp['results'][0]['geometry']['location']['lng'];

但我如何 grab 城市和州？
