Example usage:

Here’s the function api, which implements most of the commands in the twitter public api:

• static updateStatus() - update your status on twitter
• getUpdates() – get the last n updates from twitter
• getFollowers() – list your twitter friends (people following you)
• getReplies() – return replies to your posts
• getFriends() – list friends you follow on twitter
• sendDirectMessage() – direct message a friend
• etDirectMessages() – download your direct messages

You’ll want to be sure to set $url_referer to something useful, so you can set the from text for twitter (login required on twitter).

Here’s the whole TwitterUtils.php class, enjoy.
