Replies to a particular tweet, Twitter API

Here is the procedure to get the replies for a tweets

1. when you fetch the tweet store the tweetId ie., id_str
2. using twitter search api do the following query [q="to:$tweeterusername", sinceId = $tweetId]
3. Loop all the results , the results matching the in_reply_to_status_id_str to $tweetid is the replies for the post.

From what I understand, there's not a way to do that directly (at least not now). Seems like something that should be added. They recently added some 'retweet' capabilities, seem logical to add this as well.

Here's one possible way to do this, first sample tweet data (from status/show):

<status>
  <created_at>Tue Apr 07 22:52:51 +0000 2009</created_at>
  <id>1472669360</id>
  <text>At least I can get your humor through tweets. RT @abdur: I don't mean this in a bad way, but genetically speaking your a cul-de-sac.</text>

  <truncated>false</truncated>
  <in_reply_to_status_id></in_reply_to_status_id>
  <in_reply_to_user_id></in_reply_to_user_id>
  <favorited>false</favorited>
  <in_reply_to_screen_name></in_reply_to_screen_name>
  <user>
    <id>1401881</id>
     ...

From status/show you can find the user's id. Then statuses/mentions_timeline will return a list of status for a user. Just parse that return looking for a in_reply_to_status_id matching the original tweet's id.

Here is my solution. It utilizes Abraham's Twitter Oauth PHP library: https://github.com/abraham/twitteroauth

It requires you to know the Twitter user's screen_name attribute as well as the id_str attribute of the tweet in question. This way, you can get an arbitrary conversation feed from any arbitrary user's tweet:

*UPDATE: Refreshed code to reflect object access vs array access:

function get_conversation($id_str, $screen_name, $return_type = 'json', $count = 100, $result_type = 'mixed', $include_entities = true) {

     $params = array(
          'q' => 'to:' . $screen_name, // no need to urlencode this!
          'count' => $count,
          'result_type' => $result_type,
          'include_entities' => $include_entities,
          'since_id' => $id_str
     );

     $feed = $connection->get('search/tweets', $params);

     $comments = array();

     for ($index = 0; $index < count($feed->statuses); $index++) {
          if ($feed->statuses[$index]->in_reply_to_status_id_str == $id_str) {
               array_push($comments, $feed->statuses[$index]);
          }
     }

     switch ($return_type) {
     case 'array':
          return $comments;
          break;
     case 'json':
     default:
          return json_encode($comments);
          break;
     }

}
