连接数据库

mysql的全局定义

<php?
     return array('DB_TYPE'=>'mysql',
           'DB_HOST'=>'localhost',
           'DB_NAME'=>'thinkphp',
           'DB_USER'=>'root',
           'DB_PWD'=>'12345678',              
           'DB_PREFIX'=>'think_',
           'DB_PORT'=>'3306',);

pdo专用

<php?
     return array('DB_TYPE'=>'pdo',
           'DB_USER'=>'root',
           'DB_PWD'=>'12345678',
           'DB_PREFIX'=>'think_',
           'DB_DSN'=>'mysql:host=localhost;dbname=thinkphp;charset=UTF8',);

        //页面调试工具
        'SHOW_PAGE_TRACE'=>true,

home中的controller，验证数据库是否连接成功。

<?php
namespace Home\Controller;
use     Think\Controller;
use     Think\Model;
// use Home\Model\UserModel;

class UserController extends Controller{
    public function index(){
        
    }
    public function model(){
         $user = new Model('User');
         var_dump($user);
    }
}

已连接成功
