# 支持主从，分库分表的高效安全的mysql/mysqli数据库驱动封装

## 使用方法

composer require tekintian\mydb

~~~php

// 使用自动加载

require_once __DIR__ . '/vendor/autoload.php';

// 利用类继承给类起个简短的别名

class DB extends tekintian\mydb\MyDb {}

// 获取MyDb中的 $db 对象并引用赋值给 $db

$db = & DB::object();

$dbversion = $db->version(); // 使用 $db对象获取mysql版本

// DB静态方法查询数据

// 使用 DB::table('common_district') 来自动加上配置的数据库表前缀

$list = DB::fetch_all("select * from " . DB::table('common_district') . " limit 100");

print_r($list);

~~~

### 使用示例

~~~php

version(); // 获取mysql版本

$db->insert_id(); // 插入的数据ID

$db->affected_rows(); // 数据更新数量

// 获取数据库查询对象

$query = $db->query("select * from " . DB::table('common_district') . " where id <100 "); // 数据更新数量

$list=[];

while ($row = $db->fetch_array($query)) {

	$list[]=$row;

}

pp($list);

// 使用 DB::table('common_district') 来自动加上配置的数据库表前缀

$list = DB::fetch_all("select * from " . DB::table('common_district') . " limit 100");

pp($list);

// 复杂查询示例

// $query = DB::query("SELECT me.id, me.uid, me.medalid, me.dateline, me.expiration, mf.medals

// 					FROM " . DB::table('forum_medallog') . " me

// 					LEFT JOIN " . DB::table('common_member_field_forum') . " mf USING (uid)

// 					WHERE id IN ($ids)");

// while ($vv = DB::fetch($query)) {

// }

// 更多的查询方法，可参考 dz的源码

- DZ的数据库分库分表映射配置参考
