数据库访问错误Access denied for user ''@'localhost' to database 'xinjisudi'
连接数据库报错 数据库访问错误Access denied for user ''@'localhost' to database 'xinjisudi'

mysql_select_db("xinjisudi",$conn) or die("数据库访问错误".mysql_error());//打开数据库
mysql_query("set names utf8");//解决乱码
?>
啥问题 希望各位帮忙
------解决方案--------------------
$conn=mysql_connect("localhost","","")
至少 用户名都没有.密码空的话还可以
------解决方案--------------------
resource mysql_connect ( [string server [, string username [, string password [, bool new_link [, int client_flags]]]]] )
可以全部缺省(条件是用户名:root,口令:无)
如 username 不缺省,则必是正确的用户名
------解决方案--------------------
如果要缺省的话,就不应该再输入 '' 了,就直接写mysql_connect('localhost');即可了。
------解决方案--------------------
这个看来是你的用户没有xinjisudi库的权限
你要先用root之类的管理帐号登录进行赋权
------解决方案--------------------
联系管理员,让他给你 权限 最好也分配个用户名和密码。。
------解决方案--------------------
就算没有密码,也要提供一下用户名的吧
------解决方案--------------------
最稳妥的办法,创建一个带密码的账号,并对这个账号赋予访问某个数据库的权限。
