使用redis—geo api实现搜索附近的人，自己写的一个composer包

摘要：地址安装需要使用，安装中国镜像如果是应用在项目当中的话找到根目录，需要和同级基本操作初始化添加在集合中新加一个坐标结构是或者返回删除删除集合中指定元素默认存在集合，可以指定返回或如果是指定的集合名就用坐标查询附近的单位查询范围内元素

git地址

需要使用composer，安装composer, composer中国镜像

如果是应用在项目当中的话找到根目录，需要和 composer.json同级

composer require gaopengfei/redis_lbs

require_once __DIR__."/vendor/autoload.php";
$lbs = new LBSServicesLBSService();

$add_params = [
    [
        "name" => "yabao_road",
        "long" => "116.43620200729366",
        "lat" => "39.916880160714435"
    ],
    [
        "name" => "jianguomen",
        "long" => "116.4356870231628",
        "lat" => "39.908560377800676"
    ],
    [
        "name" => "chaoyangmen",
        "long" => "116.4345336732864",
        "lat" => "39.924466658329585"
    ],

        "long" => "116.4335788068771",
        "lat" => "39.921372916981106"
    ],
    [
        "name" => "cofco",
        "long" => "116.43564410781856",
        "lat" => "39.92024564137184"
    ],
    [
        "name" => "fesco",
        "long" => "116.435182767868",
        "lat" => "39.91811857809279"
    ],

返回
