javascriptfunction getDistanceBetweenPoints(latitude1, longitude1, latitude2, longitude2) { var theta=longitude1 - longitude2; var miles=Math.acos(Math.sin(deg2rad(latitude1)) * Math.sin(deg2rad(latitude2)) + Math.cos(deg2rad(latitude1)) * Math.cos(deg2rad(latitude2)) * Math.cos(deg2rad(theta))); return miles;}
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');
}
用法：
<?php $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 />'; } ?>
