laravel calculate distance between two points in Mile

Question

I'm using code to get distance between two points, it works fine but the problem is the code returns data with KM characters(e.g 56.0 km), so I want to use the pure number to get it in Mile or to use it for comparing with other values

 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]);
   }

You could multiply the result by `0.62137119` before you return it? — Tomasz Lloyd, Jun 26 '18 at 17:07
I think you didn't get what I mean, I cant multiple it because there is km characters — , Jun 26 '18 at 17:09

You can specify a units parameter in the API URL to use imperial units (feet and miles) instead of metric. Note from the docs:

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

I know, when I used this in pure php not in laravel I was able to multiple it like this $mile = $distance * 0.62137; but in laravel can't, don't know why and the result comes with km characters – Jun 26 '18 at 17:13
I don't see anything Laravel-specific that would be affecting the result being in KM. Try comparing your vanilla PHP code to your Laravel code and see what's different -- perhaps you had the `units` specified earlier, or hit a different API URL. – Aken Roberts Jun 26 '18 at 17:17

Use $distance = $data['rows'][0]['elements'][0]['distance']['value'];, that will be the distance in meters as a number.

You can convert that to miles by dividing by 1609.34.
