Tp5 project modification database

This article mainly introduces the modification of the Tp5 project database, which has certain reference value. Now I share it with everyone. Friends in need can refer to it

1. Setting model

<?php
namespace app\home\model;
use think\Db;

use think\Model;

class Crddata extends Model
{
	protected $connection = [  
        // 数据库类型  
        &#39;type&#39;        => &#39;mysql&#39;,  
        // 数据库连接DSN配置  
        &#39;dsn&#39;         => &#39;&#39;,  
        // 服务器地址  
        &#39;hostname&#39;    => &#39;127.0.0.1&#39;,  
        // 数据库名  
        &#39;database&#39;    => &#39;&#39;,  
        // 数据库用户名  
        &#39;username&#39;    => &#39;root&#39;,  
        // 数据库密码  
        &#39;password&#39;    => &#39;123456&#39;,  
        // 数据库连接端口  
        &#39;hostport&#39;    => &#39;3306&#39;,  
        // 数据库连接参数  
        &#39;params&#39;      => [],  
        // 数据库编码默认采用utf8  
        &#39;charset&#39;     => &#39;utf8&#39;,  
        // 数据库表前缀  
        &#39;prefix&#39;      => &#39;&#39;,  
    ]; 
}

2. Copy the Db class and name it Db1,

Edit database1 (database Configuration) ->Under the root directory extra

The usage is consistent with Db
