今天将本地的php从5.2.9升级到5.3.8有如下报错： ( ! ) Fatal error: Cannot redeclare class db_class in E:\website\eurobeadszone\lib\db\db.class.php on line 10 Call Stack #TimeMemoryFunctionLocation 10.0009357256{main}( )..\index.php : 0 20.00

在网上也搜寻了不少方法：

说是类似下面的修改

 

include 'blogsql.class.php'; 改成

 

include_once 'blogsql.class.php';

但是改后也不对！

求高手指点！
