How to get Distance in KM in this query

Question

$salons = Salon::select(\'salons.*\')
    ->selectRaw(\'( 6371* acos( cos( radians(?) ) *
                   cos( radians( lat ) )
                   * cos( radians(          


        

Answer 1

Try below query

$data = DB::table('salons AS S')
                ->selectRaw("
                        ( FLOOR(6371 * ACOS( COS( RADIANS( '$lat' ) ) * COS( RADIANS( S.lat ) ) * COS( RADIANS( S.lng ) - RADIANS( '$lng' ) ) + SIN( RADIANS( '$lat' ) ) * SIN( RADIANS( S.lat ) ) )) ) distance")
                ->havingRaw("distance < 25")
                ->where("category_Id" , "=" , $id)
                ->get();

$lat, $lng are variables.
