function calcDistance($lat1,$Lang1, $lat2, $Lang2)
{
    //RAD
    $b1 = ($lat1/180)*M_PI;
    $b2 = ($lat2/180)*M_PI;
    $l1 = ($Lang1/180)*M_PI;
    $l2 = ($Lang2/180)*M_PI;
    //equatorial radius
    $r = 6378.137;
    // Formel
    $e = acos( sin($b1)*sin($b2) + cos($b1)*cos($b2)*cos($l2-$l1) );
    return round($r*$e, 4);
}
