Calling PDO::setAttribute within namespaces

I want to use the built-in PDO class to connect to a mysql database.
If I understand it right, the PDO methods don't throw exceptions by default. Is this correct?
So I try to change the error mode:

$pdo = new PDO($dsn, $user, $password);

    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

My problem is that I'm using namespaces in my classes so I have to write:

$pdo = new \PDO($dsn, $user, $password);

But I don't know how to set the error mode in this context.

   $pdo = new \PDO($dsn, $user, $password); 
   $pdo->setAttribute(\PDO::ATTR_ERRMODE, \PDO::ERRMODE_EXCEPTION);

Same way you declare it initially, my friend!

Remember, PDO in itself is the class, whether you are declare a new instance (new PDO), or if you're referencing static constants (PDO::ATTR_ERRMODE). Since you're within a namespace, you must preface it with \. This applies to every occurrence of PDO, it's all the same class. So we use \PDO throughout.

That can be tricky to remember, you can also just put use \PDO; at the top, and then use PDO normally throughout. Pick one, and stick with it everywhere.
