PHP计算2点经纬度之间的距离代码，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
<div class="codetitle"><a style="CURSOR: pointer" data="9040" class="copybut" id="copybut9040" onclick="doCopy('code9040')"> 代码如下:
<div class="codebody" id="code9040">
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' => -73.917
404);
$distance = getDistanceBetweenPointsNew($point1['lat'],$point1['long'],$point2['lat'],$point2['long']);
foreach ($distance as $unit => $value) {
echo $unit.': '.number_format($value,4).'
';
}The example returns the following:miles: 2.6025
feet: 13,741.4350
yards: 4,580.4783
kilometers: 4.1884
meters: 4,188.3894
