php - 从地址获取州和县

Question

我想通过 Google API 使用地理编码从地址中获取州和县。这是我的代码:

$geocode=file_get_contents('http://maps.google.com/maps/api/geocode/json?address='.$street.''.$plz.''.$city.'&sensor=false');
        $output= json_decode($geocode);
        $lat = $output->results[0]->geometry->location->lat;
        $long = $output->results[0]->geometry->location->lng;
        $formatted_adress = $output->results[0]->formatted_address;
        $state = $output->results[0]->address_components->administrative_area_level_2;
        $county = $output->results[0]->address_components->administrative_area_level_1;

latitude、longitude 和 formatted_adress 可以找到并且我可以将结果保存在我的数据库中，但是州和县不起作用.

这是输出:

    {
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "Hauptgasse",
               "short_name" : "Hauptgasse",
               "types" : [ "route" ]
            },
            {
               "long_name" : "Solothurn",
               "short_name" : "Solothurn",
               "types" : [ "locality", "political" ]
            },
            {

               "short_name" : "Solothurn",

            }
         ],

Answer 1

根据您显示的 json 数据，您需要获取 state 和 county，如下所示:-

$state = $output->results[0]->address_components[2]->long_name;// i assume `Solothurn` is state name
$county = $output->results[0]->address_components[4]->long_name; // i assume `Schweiz` is county name

如果县名也是 Solothurn 那么只需像下面这样更改县代码:-

$county = $output->results[0]->address_components[3]->long_name;
