SQLSTATE[28000] [1045] Access denied for user 'root’@host

Question

couldn't access database with error message:

SQLSTATE[28000] [1045] Access denied for user 'root’@‘xxx.ne.jp'(using password: YES)

I have this php code.

$dsn = 'mysql:dbname=mydb;host=xxx.ne.jp';
$user = 'root';
$password ='0123';

try{
    $dbh = new PDO($dsn, $db_user, $db_password);
    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch (PDOException $e) {
    echo $e->getMessage();
}

I can login to phpmyadmin with same username and password(root/0123).
why?
Do you have any idea to fix it?

Answer 1

Here is the basic PDO connection example:

$dbh = new PDO('mysql:host=localhost;dbname=test', $user, $pass);

So include the missing host name :

$dsn = 'mysql:host=localhost;dbname=mydb;host=xxx.ne.jp';
$user = 'root';
$password ='0123';

try{
    $dbh = new PDO($dsn, $db_user, $db_password);
    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch (PDOException $e) {
    echo $e->getMessage();
}

Change localhost if running site on another host.
