是否可以喜欢/分享网站Facebook Feed中显示的Facebook帖子？

I am trying to add like/share functionality to Facebook feed posts that are displayed on my website.

In the current setup, I generate and cache a Facebook feed using PHP (FQL) which gives me access to all of the data under these tags: https://developers.facebook.com/docs/reference/fql/stream/.

So the question is, how do I craft like/share buttons to directly like/share posts that are on Facebook? Is this even possible?

Thank you.
