Can I create a database using PDO in PHP?

Question

I want to create a class which uses PDO to interact with MySQL. Can I create a new MySQL table using PDO?

Answer 1

Yes, you can.

The dsn part, which is the first parameter of the PDO constructor, does not have to have a database name. You can simply use mysql:host=localhost. Then, given you have the right privilege, you can use regular SQL commands to create a database and users, etc.

Following is an example from an install.php file. It logs in with root, create a database, a user, and grant the user all privilege to the new created database:

exec("CREATE DATABASE `$db`;
                CREATE USER '$user'@'localhost' IDENTIFIED BY '$pass';
                GRANT ALL ON `$db`.* TO '$user'@'localhost';
                FLUSH PRIVILEGES;")
        or die(print_r($dbh->errorInfo(), true));

    }
    catch (PDOException $e) {
        die("DB ERROR: " . $e->getMessage());
    }
?>
