计算两个地图坐标之间的距离

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');
}

语法：

<?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).'';
}
?>
