laravel 计算两点之间的距离（英里）

Question

我正在使用代码获取两点之间的距离，它工作正常但问题是代码 returns 数据带有 KM 字符（例如 56.0 公里），所以我想使用纯数字来以英里为单位获取它或将其用于与其他值进行比较

 public function getdistance(Request $request)
 {
  $currentaddress =$request->currentadd;
  $from = '4429 North Broadway, Chicago, IL, United States';
  $remFrom = str_replace(',', '', $from); //Remove Commas
 $from = urlencode($remFrom);
$to = $currentaddress;
$remTo = str_replace(',', '', $to); //Remove Commas
  $to = urlencode($remTo);
 $data = file_get_contents("http://maps.googleapis.com/maps/api/distancematrix/json?origins=$from&destinations=$to&language=en-EN&sensor=false");
  $data = json_decode($data,true);
 $distance = $data['rows'][0]['elements'][0]['distance']['text'];

  return response()->json([$distance]);
   }

Answer 1

您可以在 API URL 中指定 units parameter 以使用英制单位（英尺和英里）而不是公制。文档注释：

This unit system setting only affects the text displayed within distance fields. The distance fields also contain values which are always expressed in meters.

http://maps.googleapis.com/maps/api/distancematrix/json?origins=$from&destinations=$to&language=en-EN&sensor=false&units=imperial

Answer 2

使用$distance = $data['rows'][0]['elements'][0]['distance']['value'];，这将以米为单位的距离。

您可以将其除以 1609.34 换算成英里。
