Question

I got stuck at this. i am using hostinger for my website

    $server = "localhost";
    $user = ""; //Username
    $password = ""; //Password
    $database = ""; //Database
    $connection = mysqli_connect($server,$user,$password,$database);

    if (mysqli_connect_errno()) {
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
      exit();
    }

Answer 1

Answer 2

Are you sure that localhost is the right host? I would also dump the mysqli_connect_errno() value because it returns the error code from the last connection attempt, which will give you a very good indication of where the issue is. and I would check if the user u201944136_root is defined and have permissions against localhost (mysql> SHOW GRANTS FOR 'u201944136_root'@'localhost';)
