Haversine in Laravel works in this way:

                Travel::select(
                    DB::raw("travels.*,
                          ( 6371 * acos( cos( radians($lat) ) *
                            cos( radians( lat ) )
                            * cos( radians( lon ) - radians($lng)
                            ) + sin( radians($lat) ) *
                            sin( radians( lat ) ) )
                          ) AS distance"))
                ->orderBy('distance', 'asc')
                ->get();

and you will get a collection of points ordered by distance (nearest first)

Was used travel model with params lat and lng. parameter distance is added by the raw query
