php MySQL数据库 - 访问被拒绝

Question

im using phpmyadmin to access my database but when i try to access the website i am getting the following error:

     MySQL said: Documentation
#1045 - Access denied for user 'root'@'localhost' (using password: NO) 

the code to connect the php to sql is the following:

    <?php
/*
 * Generated configuration file
 * Generated by: phpMyAdmin 3.2.5 setup script by Piotr Przybylski <[e-mail]>

/* Servers configuration */
$i = 0;

/* Server: localhost [1] */
$i++;
$cfg['Servers'][$i]['verbose'] = 'localhost';

$cfg['MySQLManualBase'] = 'http://dev.mysql.com/doc/refman/5.1/en';
$cfg['MySQLManualType'] = 'searchable';

?>

the connection is a local one and there is no password to enter it, therefore i believe that the database should authenticate and authorize the access, original it used to work fine, but now and for some reason, i get access denied. any help is appreciated.

It's not good idea to use root account by your applications. Always use different users for your apps! At least one for each app.

I bet that MySQL blocks root login.

#1045 - Access denied for user 'root'@'localhost' (using password: NO)

what worries me is "using password: NO" - root without password?

Try to create new user, grant him permissions to database that you're working on and try again.
