$tmhOAuth = new tmhOAuth(array(
  'consumer_key'    => 'CORRECT_KEY',
  'consumer_secret' => 'zCORRECT_KEY',
  'user_token'      => '1CORRECT_KEY',
  'user_secret'     => 'CORRECT_KEY',
));
  $code = $tmhOAuth->request('GET', $tmhOAuth->url('1.1/statuses/user_timeline'), array(
  'screen_name' => 'MYSCREENNAME'));
$response = $tmhOAuth->response['response'];

print_r($response);

    $data = json_decode($response);
