MySQL4.1乱码问题
在MySQL4.1的安装过程中有缺省character的设置在下图中有显示
如果您所在的服务器有没有选择缺省为GB则会使用UFT8就会出现乱码
或者
只要在你连到数据库后,先执行这句
mysql_query("Set Names 'uft8'");
其中 uft8 可改成你需要的编码,e.g. gb2312 等
这个命令也可以用于 mysql 得命令行,从而可以显示正确的文字
连接数据库出现

其二:
mysql> UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd')
-> WHERE Host = 'some_host' AND User = 'some_user';
mysql> FLUSH PRIVILEGES;
