The function below use the latitude and longitude of two locations, and calculate the distance between them in both miles and metric units.

function getDistanceBetweenPointsNew($latitude1, $longitude1, $latitude2, $longitude2) {

    $miles = (sin(deg2rad($latitude1)) * sin(deg2rad($latitude2))) + (cos(deg2rad($latitude1)) * cos(deg2rad($latitude2)) * cos(deg2rad($theta)));
    $miles = acos($miles);
    $miles = rad2deg($miles);
    $miles = $miles * 60 * 1.1515;
