一个用于处理（地理）位置的简单库。

use Location\Location;
use Location\Coordinate\Coordinate2d;
use Location\Distance\Haversine;

// Amsterdam, NL.
$amsterdam = new Location(new Coordinate2d(52.3079989, 4.9715451));

// Venlo, NL.
$venlo = new Location(new Coordinate2d(51.3703748, 6.1724031));

// The distance between Venlo and Amsterdam is 132950 meters (132km 950m) 
// using the Haversine formula.
$distance = $amsterdam->calculateDistanceFromLocation($venlo, new Haversine());

请注意，目前尚不支持UTM、MGRS和USNG坐标系统。

安装

使用 Composer

$ composer require patrickkempff/location

{
    "require": {
        "patrickkempff/location": "dev-master"
    }
}

<?php
require 'vendor/autoload.php';

use Location\Location;
use Location\Coordinate\Coordinate2d;
use Location\Distance\Haversine;

// Amsterdam, NL.
$amsterdam = new Location(new Coordinate2d(52.3079989, 4.9715451));

// Venlo, NL.
$venlo = new Location(new Coordinate2d(51.3703748, 6.1724031));

// The distance between Venlo and Amsterdam is 132950 meters (132km 950m) 
// using the Haversine formula.
$distance = $amsterdam->calculateDistanceFromLocation($venlo, new Haversine());

手动安装

请注意，推荐通过 composer 安装 Location。如果您确实想手动安装 Location，可以从Location 仓库下载并解压文件到您的项目目录中。

<?php
require 'path/to/Location.php';
require 'path/to/Coordinate/Coordinate2d.php';
require 'path/to/Distance/Haversine.php';

use Location\Location;
use Location\Coordinate\Coordinate2d;
use Location\Distance\Haversine;

// Amsterdam, NL.
$amsterdam = new Location(new Coordinate2d(52.3079989, 4.9715451));

// Venlo, NL.
$venlo = new Location(new Coordinate2d(51.3703748, 6.1724031));

// The distance between Venlo and Amsterdam is 132950 meters (132km 950m) 
// using the Haversine formula.
$distance = $amsterdam->calculateDistanceFromLocation($venlo, new Haversine());
