This bit of react/http-client listens on the twitter streaming API.

Twitter streaming API listener

$buffer = '';
$request = $this->client->request($method, $url, $headers);
$request->on('response', function($response) use (&$buffer) {
    $response->on('data', function($data) use (&$buffer) {
        $buffer .= $data;
        if (strpos($buffer, PHP_EOL) !== false) {
            $tweets = explode(PHP_EOL, $buffer);
            $buffer = array_pop($tweets);
            foreach ($tweets as $tweet) {
                if (strlen(trim($tweet)) > 0) {
                    $tweetObject = json_decode($tweet);
                    $this->saveTweet($tweetObject);
                }
            }
        }
    });
});
$request->end();

I look forward to giving this a try with our campfire chatroom.. hopefully using SSL isn't harder.
