Не могу понять как подключить бд через PDO
Uncaught PDOException: SQLSTATE[HY000] [2019] Unknown character set
class connectDB
{
private $host = 'localhost';
private $user = 'root';
private $password = '';
private $db = 'registration';
private $charset = 'utf-8';
private $opt = [
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
PDO::ATTR_EMULATE_PREPARES => false,
];
public $pdo;
public function connect()
{
$this->pdo = new PDO("mysql:host=$this->host;dbname=$this->db;charset=$this->charset",$this->user,$this->password,$this->opt);
}
public function close_connect()
{
$this->pdo = null;
}
}
