Database connection issue

[Cupernicus]

To accomplish this, I am doing the following, but I am encountering an error. Does anyone understand this? ERROR: SQLSTATE[28000] [1045] Access denied for user 'farmas49_1'@'localhost' (using password: YES) The error is occurring while trying to establish a database connection using PHP's PDO to a MySQL database named 'petroofisi' on the localhost server with the username 'petroofisi' and password 'petroofisi20A'. If you have knowledge about this issue, your assistance would be greatly appreciated. Thank you.
