我目前正在使用Google Maps API来获得经度和纬度,形成了用户的街道,街道号码和邮政编码。
我也想从地图API结果中抓住他们的城市并说明。XML文档格式却很奇怪,我不确定我应该如何引用它(这与我抓住长长和lat的方式不同)。
这就是我加载地图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);
我得到了长长的时间:
$lati = $resp['results'][0]['geometry']['location']['lat'];
$longi = $resp['results'][0]['geometry']['location']['lng'];
但是我该如何抓住城市和州?

刚刚通过循环运行代码来回答我自己的问题。请让我知道您是否有更好的方法!
foreach($resp['results'][0]['address_components'] as $address_componenets) {
if($address_componenets["types"][0]=="country") {
$country = $address_componenets["long_name"];
}
if($address_componenets["types"][0]=="administrative_area_level_1") {
$state = $address_componenets["long_name"];
}
if($address_componenets["types"][0]=="locality") {
$city = $address_componenets["long_name"];
}
}
