Google Maps API - 使用 PHP 检索城市和州答案

【问题标题】：Google Maps API - Retrieving city and state using PHPGoogle Maps API - 使用 PHP 检索城市和州

【问题描述】：

我目前正在使用 Google Maps API 从用户的街道、街道号码和邮政编码中获取经度和纬度。

我还想从 Maps API 结果中获取他们的城市和州。虽然 XML 文档的格式很奇怪，但我不确定我应该如何引用它（这与我获取经纬度的方式不同）。

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);

然后我得到了经纬度：

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

但我如何获取城市和州？

【解决方案1】：

刚刚通过循环运行代码回答了我自己的问题。如果您有更好的方法，请告诉我！

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"];
    }   
}
