Getting facebook mutual friends of some users (not my friends)

Question

I am trying to get mutual friends count of users that aren't my friends.

This is the code (after auth.):

$fb_result = $facebook->api('/me/mutualfriends/'.$other_user_fb_id);

But when looping this code over 10-20 users it is too long\\slow.

Is there any other method?

something like:

$fb_result = $facebook->api('/me/mutualfriends/'.user_fb_id1.','.user_fb_id2.','.....);

Answer 1

You can use:

$fb_result = $facebook->api("/{$user_fb_id2}/mutualfriends/{$user_fb_id1}");

Note that, the user: user_fb_id2 must be the user of your application for this to work.

UPDATE: You can use FQL Queries and Batch requests for this purpose.
