Unable To Connect The MYSQL Database Access Denied For User

While I connect the from source code PHP to mysql database I got the following error message.
[08-Sep-2010 09:13:41] PHP Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'wbroot'@'localhost' (using password: YES) in /home/withoutb/public_html/dbconnect.php on line 8
These error message clearly says the Database user wbroot can not able to connect to Source Coding.
SOLUTION

These problem occur when we are give the the wrong user name or password.
Then I enter the correct user name and password finally the problem has been resolved.
worngusername : wbroot
Correct username: abcdsof_wbroot
