I am getting this error trying to connect to DB,
having config.php file where pdo object is being created:
$pdo = new PDO($dsn, $user, $pass, $opt);   
after that inside the user.php I have a class stating the following:
require_once('config.php');
class USER {
    private $conn;          
    public function __construct($pdo) {     
        $this->conn = $pdo;
    }   
The object seems to be available inside the user.php file but not inside the class. Any suggestion how to overcome this ?
error is: Warning: Missing argument 1 for USER::__construct()
Thanks in advance.
