Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: YES)
Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: YES) in E:\web\business\ty_admin\ty_config.inc.php on line 12

Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in E:\web\business\ty_admin\ty_config.inc.php on line 13

  
在本地调试的好好的 什么问题都没有

但是传到服务器就出错了 不知道为什么
 


------解决方案--------------------
用phpmyadmin将root改成全局(输入%)，就可以了
