How to modify sample Heroku facebook app to show friend's likes

Question

In the sample app that Heroku starts you out with when you make a Facebook php app, there's this line.

$likes = idx($facebook->api('/me/likes?limit=4'), 'data', array());

This will get 4 of my likes and store them in an array. But what I want to do is get 4 things that my friend likes.

I tried replacing "me" with the id of a friend, but it didn't work. What changes do I have to make to fetch my friend's likes?

You obviously need the friends_likes permission. Here's an official tutorial on how to pull the movies your friends' like.
