Description:
------------
It would be helpful and spiffy to have a function or member variable on MySQLi objects that one could use to determine if the connection was a success or failure.  According to the documentation, the solution is to call the mysqli_connect_errno() function after construction of the object, but doing so sort of eliminates the "object oriented-ness" of the design, and causes sloppy code (i.e. extra variables required to store status of different connection successes, etc.).

I don't understand. var_dump($no_connected_mysqli_object) gives you.

And:

$m = @new mysqli("localhost", "root", "rooti");
var_dump(@$m->connect_error);

There's your propery. If you suppress warnings you can even access it.
