why?

Thanks for the contribution @piotr-cz.

@dereuromark Before this change, if using that example, then the line doing $this->pdo->setAttribute would result in a fatal error as $this->pdo had not yet been assigned (it was happening after). Now it'll work as expected. 😄

Sry the diff looked differently for me so I saw it being accessed before Set.
Makes sense as in this pr 👍
