Question

我正在使用代码获取两点之间的距离，效果很好，但是问题是代码返回的数据带有KM个字符（例如56.0 km），因此我想使用纯数字将其获取为Mile或用它与其他值进行比较

 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）代替公制。来自文档的注意事项：

此单位制设置仅影响在距离字段中显示的文本。距离字段还包含始终以米表示的值。

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'];，这将是距离，以米为单位。

您可以用1609.34除以将其转换为英里。

响应（针对this request）：

{
   "destination_addresses" : [ "New York, NY, USA" ],
   "origin_addresses" : [ "4429 North Broadway, Chicago, IL 60640, USA" ],
   "rows" : [
      {
         "elements" : [
            {
               "distance" : {
                  "text" : "1,294 km",
                  "value" : 1293988    // <============ distance in meters
               },
               "duration" : {
                  "text" : "12 hours 24 mins",
                  "value" : 44618      // <============ duration in seconds
               },
               "status" : "OK"
            }
         ]
      }
   ],
   "status" : "OK"
}

laravel计算英里之间两点之间的距离
