-----------------------------------------------------------------------------------

[](#本库基于-ip2region-简单整合方便使用composer来管理)

[ip2region](https://github.com/lionsoul2014/ip2region) - 最自由的ip地址查询库，ip到地区的映射库，提供Binary,B树和纯内存三种查询算法，妈妈再也不用担心我的ip地址定位。

### 1. 99.9%准确率，定时更新：

[](#1-999准确率定时更新)

数据聚合了一些知名ip到地名查询提供商的数据，这些是他们官方的的准确率，经测试着实比纯真啥的准确多了。
每次聚合一下数据需要1-2天，会不定时更新。

### 2. 标准化的数据格式：

[](#2-标准化的数据格式)

每条ip数据段都固定了格式：*城市Id|国家|区域|省份|城市|ISP*

只有中国的数据精确到了城市，其他国家只能定位到国家，后前的选项全部是0，已经包含了全部你能查到的大大小小的国家。 （请忽略前面的城市Id，个人项目需求）

### 3. 体积小：

[](#3-体积小)

数据库文件ip2region.db只有1.5M

### Composer 安装

[](#composer-安装)

```
composer require chenyongze/ip2region

```

### ip2region 使用

[](#ip2region-使用)

```
$ip2region = new Ip2Region();

$ip = '101.105.35.57';

$info = $ip2region->btreeSearch($ip);

var_export($info, true);

// array (
//     'city_id' => 2163,
//     'region' => '中国|华南|广东省|深圳市|鹏博士',
// )
```
