Answer 1

The following should work for you to implement the haversine formula in an SQL query. My answer is assuming you have a model setup to correspond with the database table "aziende".

$lat = floatval($response['results'][0]['geometry']['location']['lat']);
$lng = floatval($response['results'][0]['geometry']['location']['lng']);
$radius = 5;
$distance = DB::raw("*, ( 6371 * acos( cos( radians($lat) ) * cos( radians( lat ) ) * cos( radians( lng ) - radians($lng) ) + sin( radians($lat) ) * sin( radians( lat ) ) ) ) AS distance");
$aziende = Aziende::select($distance)->orderBy('distance')->where('distance', '<=', $radius)->get();
