GeoPoint代表PHP的地理点，包括转换、点对点距离和边界框计算。

使用方法

$statueOfLibertyPoint = new GeoPoint(40.689604, -74.04455, GeoPoint::DEGREES);

构造函数选项

• latitude -- 纬度
• longitude -- 经度
• format -- 传入的经纬度格式的GeoPoint::DEGREES或GeoPoint::RADIANS

方法

• getLatitude(): 返回点的纬度，格式为点的格式（GeoPoint::DEGREES或GeoPoint::RADIANS）
• getLongitude(): 返回点的经度，格式为点的格式（GeoPoint::DEGREES或GeoPoint::RADIANS）
• distanceTo(GeoPoint, kmOrMiles): 使用GeoPoint::KILOMETERS或GeoPoint::MILES计算到另一个GeoPoint实例的距离。
• boundingCoordinates(distance, radius, kmOrMiles): 计算从点出发的距离为distance的边界坐标，并返回一个包含边界框的SW和NE点的数组。如果未提供radius，则使用地球半径。距离以公里计算，除非kmOrMiles设置为GeoPoint::MILES。

静态方法

• GeoPoint::degreesToRadians(value): 将度值转换为弧度
• GeoPoint::radiansToDegrees(value): 将弧度值转换为度
• GeoPoint::milesToKilometers(value): 将英里值转换为公里
• GeoPoint::kilometersToMiles(value): 将公里值转换为英里

运行测试

php composer.phar test

背景

这是受到David Wood的JavaScript端口的启发，该端口基于Jan Philip Matuschek的Java代码，该代码在Jan Philip Matuschek的Finding Points Within a Distance of a Latitude/Longitude Using Bounding Coordinates中展示。
