CodeIgniter-REST Client is a CodeIgniter library which makes it easy to do use REST services/API's such as Twitter, Facebook and Flickr, wether they are public or hidden behind HTTP Basic/Digest.
$this->load->library('rest', array( 'server' => 'http://twitter.com/' )); $tweets = $this->rest->get('statuses/user_timeline/'.$username.'.xml');
This is clearly a VERY simple example and more can much more can be done with it. For up-to-date documentation keep an eye on the following link:
