上面这个代码是我在百度搜到的解决办法，地址：http://www.cnblogs.com/imbin/archive/2010/07/06/1772333.html
但是把文件传到根目录结果提示：

  2. Fatal error: Maximum execution time of 30 seconds exceeded in D:\idcbjhost\ichumi\web\includes\cls_mysql.php on line 267

  4. Fatal error: Maximum execution time of 30 seconds exceeded in D:\idcbjhost\ichumi\web\includes\cls_session.php on line 233

求解，请高人指点一下！
