分析一下哦
PHP代码：
首先header("Content-Type:text/html;charset=GB2312");
是网页翻转
链接
不过这段感觉有问题！
$dbhost="
localhost
";
本地肯定错
换IP 如202.0.4.45
结果
就正常了$dbuser="root";
这行
账户$dbpw="mysqladmin";
账户
密码
$dbname="chat";
数据库
表名$error_up="br";
输出
换行$dbcharset
=
'gbk'; 字符
通常GBK
就行
这一一分析完
你就知道哪里出错了
祝
早日排错成功！
不行的，没有权限
还不如用下面的方法：
直接配置到本地?
