Facebook: Find out when user liked an URL

Question

I can get pair of user_id - url from url_like table.
The only two columns are, as mentioned, user_id, url

Answer 1

I found this solution that solves my problem

I rely on FQL

public static $since = '2012/01/01';
...
...

// $target1 stands for "me", it has value of my FB ID
// So I am selecting all links I liked in past year
$object_id_raw = static::$facebook->api(array(
    'method'    => 'fql.query',
    'query' => "SELECT link_id FROM link WHERE owner = {$target1} AND created_time > ".strtotime(static::$since)
));
// Just extracting IDs for later usage
$object_id = array();
foreach($object_id_raw as $oid):
    array_push($object_id, $oid['link_id']);
endforeach;

// - friendId stands for FB ID of my friends
// This query is selecting from links I liked,that means we have them liked both...
// This API call returns object ID's (ID's of links). Do whatever you want with them...
$result = static::$facebook->api(array(
    'method'    => 'fql.query',
    'query' => "SELECT object_id FROM like WHERE object_id IN ('".implode("','", $object_id)."') AND user_id = {$friendId}"
));
