- illuminate/redis: >=5.5
This package is auto-updated.

README
基于redis的geoHash和坐标距离计算公式实现坐标间的距离计算
Requirements
Redis >= 3.2.0
Usage
composer require bastphp/calculate-distance
<?php
namespace App\Http\Controllers;
use Dashan\calculateDistance\Distance;
class TestController extends Controller
{
public function index()
{
//默认使用redis作为驱动
$distanceObj = Distance::distanceCalculate();
//使用公式的方式计算
// $distanceObj = Distance::distanceCalculate('formula');
//返回两个坐标间的距离
$res = $distanceObj->calculateOneCoordinate([113.610042,34.758417,'a'],[113.620685,34.728388,'b']);
$base = [113.610042,34.758417,'a'];
$need = [[113.620685,34.728388,'b'],[114.620685,32.728388,'c']];
$dis = 12;
//设置单位
$distanceObj->setUnit('km')//支持km和m
->setOrder('asc')//支持asc和desc
->setLimit(3)//要取的个数
//->calculateRadius($base,$need,$dis);//计算方圆12km内在给定的坐标内据我最近的三个
->calculateOrder($base,$need);//计算给定的坐标距基础坐标的按距离由近到远排序
}
}
