Как мне подключиться к mysql dbase и где мне не хватает ссылки

Warning: mysqli_connect(): (HY000/1045): Access denied for user 'mfana'@'localhost' (using password: YES) in C:\xampp\htdocs\First_File\database.php on line 9
Connection failed: Access denied for user 'mfana'@'localhost' (using password: YES)

Что я уже пробовал:

<?php

$servername = "localhost";
$username = "mfana";
$password = "1234";
$dbname = "mfana";

// Create connection
$connection = mysqli_connect($servername, $username, $password, $dbname);

// Check connection
if (!$connection) {
    die("Connection failed: " . mysqli_connect_error());
}

?>
