+# ip2region SDK for PHP (定期更新数据版)
+
+[![Author](https://img.shields.io/badge/author-@chinayin-blue.svg)](https://github.com/chinayin)
+[![Software License](https://img.shields.io/badge/license-Apache--2.0-brightgreen.svg)](LICENSE)
+[![Latest Version](https://img.shields.io/packagist/v/chinayin/ip2region.svg)](https://packagist.org/packages/chinayin/ip2region)
+[![Total Downloads](https://img.shields.io/packagist/dt/chinayin/ip2region.svg)](https://packagist.org/packages/chinayin/ip2region)
+![php 7.1+](https://img.shields.io/badge/php-min%207.1-red.svg)
 
 ### Installation
+
+运行环境要求 PHP 7.1 及以上版本，以及[cURL](http://php.net/manual/zh/book.curl.php)。
+
+#### 定期更新数据版
+
+特点：`xdb数据`封装在composer包内，数据会定期更新
+
 > composer require chinayin/ip2region
 
+#### 官方原生查询包
+
+特点：包更小，数据路径自定义
+
+使用方法：[github.com/chinayin/ip2region-core](https://github.com/chinayin/ip2region-core-php)
+
 ### Quick Examples
+
+#### 完全基于文件的查询
+
 ```php
-use lionsoul2014\Ip2Region;
+use ip2region\Ip2Region;
 
-$ip2region = new Ip2Region;
-
-$ip = '220.181.38.150';
-$data = $ip2region->memorySearch($ip);
-$data = $ip2region->binarySearch($ip);
-$data = $ip2region->btreeSearch($ip);
-
-// binary算法/b-tree算法/Memory算法：
-// 0.x毫秒/0.1x毫秒/0.1x毫秒
-// 任何客户端b-tree都比binary算法快，当然Memory算法固然是最快的！
+$ip = '1.2.3.4';
+try {
+    $searcher = Ip2Region::newWithFileOnly();
+    $region = $searcher->search($ip);
+    // 或
+    $region = Ip2Region::search($ip);
+    var_dump($region);
+} catch (\Exception $e) {
+    var_dump($e->getMessage());
+}
 ```
+
+> 备注：并发使用，每个线程或者协程需要创建一个独立的 searcher 对象。
+
+#### 缓存 VectorIndex 索引
+
+如果你的 php 母环境支持，可以预先加载 vectorIndex 缓存，然后做成全局变量，每次创建 Searcher 的时候使用全局的
+vectorIndex，可以减少一次固定的 IO 操作从而加速查询，减少 io 压力。
+
+```php
+use ip2region\Ip2Region;
+
+$ip = '1.2.3.4';
+try {
+    $region = Ip2Region::newWithVectorIndex()->search($ip);
+    var_dump($region);
+} catch (\Exception $e) {
+    var_dump($e->getMessage());
+}
+```
+
+> 备注：并发使用，每个线程或者协程需要创建一个独立的 searcher 对象，但是都共享统一的只读 vectorIndex。
+
+#### 缓存整个 xdb 数据
+
+如果你的 PHP 母环境支持，可以预先加载整个 xdb 的数据到内存，这样可以实现完全基于内存的查询，类似之前的 memory search 查询。
+
+```php
+use ip2region\Ip2Region;
+
+$ip = '1.2.3.4';
+try {
+    $region = Ip2Region::newWithBuffer()->search($ip);
+    var_dump($region);
+} catch (\Exception $e) {
+    var_dump($e->getMessage());
+}
+```
+
+> 备注：并发使用，用整个 xdb 缓存创建的 searcher 对象可以安全用于并发。
