Filter Facebook Stream by Post privacy?

Question

Hi there, i query some wall data within my facebook tab. I was wondering how to filter the data (query) to show only post which are visible to a certain country.

$query = "  SELECT 
            post_id, created_time, attachment,action_links, privacy
        FROM 
            stream 
        WHERE 
            source_id = ".$page_id." 
            AND viewer_id = ".$user_id."
            AND actor_id = ".$actor_id."
        LIMIT
            50";

The Output already show Australia: But how to filter for Australia-Only.

I think you'll have to add another filter to the query:

$query = "  SELECT 
        post_id, created_time, attachment,action_links, privacy
    FROM 
        stream 
    WHERE 
        source_id = ".$page_id." 
        AND viewer_id = ".$user_id."
        AND actor_id = ".$actor_id."
        AND privacy = ".$your_privacy_filter // Austria, in this case.
    LIMIT
        50";

Maybe the filter has to be like this:

//...
"AND privacy.description = ".$your_privacy_filter
