To access global objects like PDO and DateTime, you need to prefix them with a backslash. So you then have two options.

First, either use the classes you wish to use in your name-spaced class file:

setAttribute(\PDO::ATTR_ERRMODE, \PDO::ERRMODE_EXCEPTION);
        }
        catch (PDOException $e) {
            echo $e->getMessage();
            exit;
        }
    }
}

Or just use the backslash-prefixed declarations within your class:

setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        }
        catch (\PDOException $e) {
            echo $e->getMessage();
            exit;
        }
    }
}

Personally, I prefer the first approach.
