Simple PHP class for Twitter API OAuth?

Yesterday I discovered that the class that we use no longer can help us with a status update on Twitter, because it is based on a simple authorization which is not available since yesterday. Used class from Felix Oghina, the use of which, in principle, boiled down to:

$twitter = new Twitter(TWITTER_LOGIN, TWITTER_PASSWORD);
$success = $twitter->update($newstatus);

Couldn't find a suitable class for OAuth. I would be grateful.
