本文小编将为你奉上10个超级有用的PHP代码片段。

1.查找Longitudes与Latitudes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);
}

$point1 = array(lat =
