我用php操作数据库总出现错误，连接数据库还没有问题

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: YES) in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\xuexi\index.php on line 31

Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\xuexi\index.php on line 34

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\xuexi\index.php on line 36
这段错误的原代码是：

Answer 1

1、Warning: mysql_connect()...是数据库没有连接上
2、Warning: mysql_select_db()....，因会没连接上，所以无法选择数据库
3、Warning: mysql_query()...，无法选择到数据库当然不能对数据库进行操作
。。。建议你检验一下数据库的链接密码是否正确或者PHP+Mysql环境是否配置好！

Answer 2

数据库未连接上。。。。。

Answer 3

链接数据库错误
