PDO gives error “could not find driver”

Question

<?
$dsn = 'mysqli:dbname=websiteusers;host=localhost';
$user = 'root';
$password = '123';

    $dbh = new PDO($dsn, $user, $password);
} catch (PDOException $e) {
    echo 'Подключение не удалось: ' . $e->getMessage();
}
?>

It gives error could not find driver. What can i do?

Answer 1

As far as I know and the php docs for PDO are saying is that PDO doesn't support mysqli since there is an own class/adapter handling mysqli connections.

Supported PDO Drivers

MySQLi

Answer 2

Perhaps the PDO driver for mysql is not enabled on your server. Check your php.ini file for the following line:

;extension=php_pdo_mysql.dll

Answer 3

该驱动程序称为mysql，而不是mysqli。
