Question

我有一个包含地址的String php变量。让我们说$ adress ='Universitätsring1,1010Wien'。

有没有办法将此变量转换为Google地图坐标并将其保存在其他变量中？

并且真的不知道如何使用地理编码。

谢谢！

Answer 1

是的，您可以使用 Google地图API地理编码

来完成此操作

地理编码是转换地址的过程（如“1600” Amphitheatre Parkway，Mountain View，CA“）进入地理坐标（如纬度37.423021和经度-122.083739），您可以使用将标记放在地图上或定位地图。

例如：

https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=YOUR_API_KEY

Reference

它将返回JSON或XML，如：

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "1600",
               "short_name" : "1600",
               "types" : [ "street_number" ]
            },
            {
               "long_name" : "Amphitheatre Pkwy",
               "short_name" : "Amphitheatre Pkwy",
               "types" : [ "route" ]
            },
            {
               "long_name" : "Mountain View",
               "short_name" : "Mountain View",
               "types" : [ "locality", "political" ]
            },
            {
               "long_name" : "Santa Clara County",
               "short_name" : "Santa Clara County",
               "types" : [ "administrative_area_level_2", "political" ]
            },
            {
               "long_name" : "California",
               "short_name" : "CA",
               "types" : [ "administrative_area_level_1", "political" ]
            },
            {
               "long_name" : "United States",
               "short_name" : "US",
               "types" : [ "country", "political" ]
            },
            {
               "long_name" : "94043",
               "short_name" : "94043",
               "types" : [ "postal_code" ]
            }
         ],
         "formatted_address" : "1600 Amphitheatre Parkway, Mountain View, CA 94043, USA",
         "geometry" : {
            "location" : {
               "lat" : 37.4224764,
               "lng" : -122.0842499
            },
            "location_type" : "ROOFTOP",
            "viewport" : {
               "northeast" : {
                  "lat" : 37.4238253802915,
                  "lng" : -122.0829009197085
               },
               "southwest" : {
                  "lat" : 37.4211274197085,
                  "lng" : -122.0855988802915
               }
            }
         },
         "place_id" : "ChIJ2eUgeAK6j4ARbn5u_wAGqWA",
         "types" : [ "street_address" ]
      }
   ],
   "status" : "OK"
}

您可以使用Google地理编码API 您需要在google开发者控制台中注册应用程序，然后您可以使用您的地址发送请求，例如
https://maps.googleapis.com/maps/api/geocode/json?address=Universitätsring 1, 1010 Wien&key=YOUR_API_KEY 阅读本指南，应该有所帮助。

Answer 3

是的，您可以使用地理编码提供的xml，可以将地址作为参数，基于您可以得到lat和long：

$adress = 'Universitätsring 1, 1010 Wien';
$adress = urlencode($adress);
$url = 'http://maps.googleapis.com/maps/api/geocode/xml?address=' . $adress . '&sensor=true';
  $xml = simplexml_load_file($url);
  $status = $xml->status;
  if ($status == 'OK') {
      $latitude = $xml->result->geometry->location->lat;
      $longitude = $xml->result->geometry->location->lng;
  }

如果你想将它作为json或数组，你可以转换xml：

$adress = 'Universitätsring 1, 1010 Wien';
$adress = urlencode($adress);
$url = 'http://maps.googleapis.com/maps/api/geocode/xml?address=' . $adress . '&sensor=true';
  $xml = simplexml_load_file($url);
  $json = json_encode($xml);
  $array = json_decode($json, true);
  if ($array['status'] == 'OK') {
      $latitude = $array['result']['geometry']['location']['lat'];
      $longitude = $array['result']['geometry']['location']['lng'];
      echo $latitude;
      echo $longitude;
  }

将字符串转换为Google坐标
