Question

 foreach($friends_array as $user) {
    $argstag = array('to' => $user);
    $argstag['x'] = $locations_x[$i];
    $argstag['y'] = $locations_y[$i];
    $datatag = $facebook->api('/' . $photo_id . '/tags', 'post', $argstag);
    $i++;
 }

Instead of doing this in loop (multiple api requests), Is there a way to do it in a single api request?

Answer 1

below code works for me provided array $friends have less equal 50 friends:

$tags = array();
 foreach ($friends as $friend)
         {
            $tag = array();
            $tag['tag_uid'] = $friend;
            $tag['x'] = rand() % 100;
            $tag['y'] = rand() % 100;
            $tags[] = $tag;
         }
          $argstag = array(
            'tags' => $tags
          );
          $facebook->api("$photoId/tags","POST", $argstag);
