问题
With the new "Reply" to "Comments" feature on Facebook, I've noticed that replies to comments are treated the same as comments. But I was wondering if there is anyway to distinguish the two?
回答1:
Yes. You can query each comment object in the Graph API for the value of its parent field. If the comment in question is a reply, then the value of the parent field will be a reference to the parent comment. Otherwise, no value is returned.
Reference here: https://developers.facebook.com/docs/reference/api/Comment/

You first have to enable July Breaking Changes from your app advanced settings
Then use the fields parameter with the comments graph API and include the parent.field(id) column with the and also the filter parameter with the stream value. the final result :
{POST_ID}/comments?filter=stream&fields=parent.fields(id),message,from,likes
this should return both comments and replies with the parent element which has the comment id that the reply belongs to
-- update
and for better array arrangement for replies you can use the following to merge replies with the actual comment array you can include comments.summary(true) in the fields parameter
{POST_ID}/comments?limit=0&filter=toplevel&fields=comments.summary(true),message,from,likes
filter parameter is optional
for more info about the fields : http://developers.facebook.com/docs/reference/api/Comment/
and in case you want to do it in FQL, check this post's comments http://developers.facebook.com/blog/post/2013/04/03/new-apis-for-comment-replies/

You can get comment replies in this way.
/{{POST_ID}}/?fields=comments{comments}&access_token={{ACCESS_TOKEN}}
You can get any sub info(from,id) of comment replies by just nesting fields inside comments like this:
/{{POST_ID}}/?fields=comments{comments,from,id}&access_token={{ACCESS_TOKEN}}

If you're listening for comments on the 'feed' webhook, you should check if:
entry[0][changes][0][value][post_id] === entry[0][changes][0][value][parent_id]
This will be true for top-level (new) comments, and false for replies to comments.

To piggy back off @sujit's answer I took his answer and in one call from the feed you can get the entire feed, comments and replies to comments as well as associated images to those comments and replies in one shot.
Here is the code
https://graph.facebook.com/$get_facebook/feed?access_token=$facebook_accesstoken&client_id=$facebook_appid&client_secret=$facebook_appsecret&metadata=1&fields=id,status_type,created_time,from,message,comments{comments{attachment,from,id,message},from,id,message,attachment},picture,link,icon
