*/ 
class BaseDAO 
{ 
var $_db = null; 
var $_table = null; 
function BaseDAO($config) 
{ 
$this->_db = new MysqlDB(); // 这里的不能进行操作 
} 
/** 
* 获取处理 
* 
* @param array $filter // 过滤条件 
* @param string $field // 获取字段 
* @param int $page // 当前页 
* @param int $limit // 页数 
*/ 
function fetch($filter = array(),$field = "*",$page = 1,$limit = null) 
{ 
$this->_db->select($filed)->from($this->_table)->where($filter)->limit($page,$limit);
