php方面：以下代码可以屏蔽php注意级别的错误，即 抛出任何非注意错误
[php] error_reporting(e_all&~e_notice);
error_reporting(e_all&~e_notice);
开启session的方法，开启后就可以使用$_sesion咯。
session是保存在服务端的东西噢。启动后会给 浏览器发送一个 session的id，是cookies方式的
[php] session_start();
session_start();
如果浏览器禁用了cookies那也不要紧，可以把session写到url里就好咯.嘿嘿
[php] session_name.'='.session_id()
session_name.'='.session_id() 附上我写好的 adminaction，只有登陆功能哦
[php] force_compile = true;

修改了 mysql.class.php 加了一个函数 fine，这样返回的数组就是 一维的咯，方便些
[php] /**

+----------------------------------------------------------
* @access public
+----------------------------------------------------------
* @param
+----------------------------------------------------------
*/
public function fine(){
$select_sql = 'select ';
$fields = isset($this->query_list['fields'])?$this->query_list['fields']:'*';
$select_sql.=$fields;
$select_sql.= ' from `'.$this->query_list['table'].'` ';
isset($this->query_list['join'])?($select_sql.=$this->query_list['join']):'';
isset($this->query_list['where'])?($select_sql.=' where '.$this->query_list['where']):'';
isset($this->query_list['group'])?($select_sql.=' group by'.$this->query_list['group']):'';

isset($this->query_list['limit'])?($select_sql.=' 1,1'):'';
//echo '
