phpgeo是一个用于计算地理坐标之间高精度距离。
示例代码:
<?phpuse Location\Coordinate;use Location\Distance\Vincenty;$coordinate1 = new Coordinate(19.820664, -155.468066); // Mauna Kea Summit$coordinate2 = new Coordinate(20.709722, -156.253333); // Haleakala Summit$calculator = new Vincenty();echo $calculator->getDistance($coordinate1, $coordinate2); // returns 128130.850 (meters; ≈128 kilometers)
