Re: [Discuss] Add PDO disconnect() and isConnected()

> I generally agree that there's little value to a disconnect() action; unset($pdo) is already sufficient. See the point again about persistent connections. The user has no means to disconnect in that case. > I recommend to use a name that deters users from using it in normal operations, e.g. pdo->debug_manual_disconnect(). Considering the above as well, a possible stance to take could be to introduce it as persistent_disconnect(). We could then decide whether it should function on "regular" connections as well.
