Warning: mysqli::mysqli(): (HY000/1045): Access denied for user 'database'@'localhost' (using password: NO) in [duplicate]

Answer 1

You said your database name is typen, and generally default database username is root with no password. Try below code:

$servername = "localhost";
$username = "root";
$password = "";
$db = "typen";

$conn = new mysqli($servername, $username, $password,$db);
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
