导读：<?PHP

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

$theta = $longitude1 - $longitude2;

$miles = (sin(deg2rad($latitude1)) * sin(deg2rad($lati

<?PHP

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

$theta = $longitude1 - $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;

$feet = $miles * 5280;

$yards = $feet / 3;

$kilometers = $miles * 1.609344;

$meters = $kilometers * 1000;

return compact('miles','feet','yards','kilometers','meters');

}

$point1 = array('lat' => 40.770623,'long' => -73.964367);

$point2 = array('lat' => 40.758224,'long' => -73.917404);

$distance = getdistanceBetweenPointsNew($point1['lat'],$point1['long'],$point2['lat'],$point2['long']);

foreach ($distance as $unit => $value) {

echo $unit.': '.number_format($value,4).'<br />';

}

?>
