運(yùn)行user方法時，無法連接數(shù)據(jù)庫。

出錯提示

數(shù)據(jù)庫配置：

<?php
return?array?(
		'DB_TYPE'?=>?'mysql',?//?數(shù)據(jù)庫類型
		'DB_HOST'?=>?'localhost',?//?服務(wù)器地址
		'DB_NAME'?=>?'user',?//?數(shù)據(jù)庫名
		'DB_USER'?=>?'root',?//?用戶名
		'DB_PWD'?=>?'',?//?密碼
		'DB_PORT'?=>?'3306',?//?端口
		'DB_PREFIX'?=>?'mk_'?
)?//?數(shù)據(jù)庫表前綴
;

方法調(diào)用：

<?php
//?本類由系統(tǒng)自動生成，僅供測試用途
class?IndexAction?extends?Action?{
	public?function?index()?{
		echo?'333333';
		//?$this->show('<style?type="text/css">*{?padding:?0;?margin:?0;?}?div{?padding:?4px?48px;}?body{?background:?#fff;?font-family:?"微軟雅黑";?color:?#333;}?h1{?font-size:?100px;?font-weight:?normal;?margin-bottom:?12px;?}?p{?line-height:?1.8em;?font-size:?36px?}</style><div?style="padding:?24px?48px;">?<h1>:)</h1><p>歡迎使用?<b>ThinkPHP</b>！</p></div><script?type="text/javascript"?src="http://tajs.qq.com/stats?sId=9347272"?charset="UTF-8"></script>','utf-8');
	}
	public?function?user()?{
		$user?=?new?Model?(?'user'?);
		$data?=?$user->select?();
		dump?(?$data?);
		//?$model?=M();
		//?$data=$model->query('select?*?from?mk_user');
		//?//?dump($data);
		//?echo?c('name');
		//?trace('name',C('name'));
		$this->display?();
	}
}

index.php:

<?php
define?(?'APP_DEBUG',?TRUE?);
define?(?'APP_NAME',?'App'?);
define?(?'APP_PATH',?'./App/'?);
require?('./ThinkPHP/ThinkPHP.php');

debug.php:

<?php
return?array?(
		'name'?=>?'Donsen@debug',
		'SHOW_PAGE_TRACE'?=>?true?
)?//?顯示頁面trace信息
;

明明已經(jīng)配置了數(shù)據(jù)庫，但是顯示沒有連接數(shù)據(jù)庫。
