phpFlickr

All versions up through 1.3.1 have had a bug in photos_getNotInSet(). If a call is made while there is only one photo not in a set, the array structure of the result won't be quite the same. This is because of the way that the xml parser arranges things. If this is a concern, replace the entire function (starting on line 596 in phpFlickr.php) with the code below. I've fixed the problem in CVS and the next update will have the correct code.

    function photos_getNotInSet($extras = NULL, $per_page = NULL, $page = NULL)
    {
        /* http://www.flickr.com/services/api/flickr.photos.getNotInSet.html */
        if (is_array($extras)) {
            $extras = implode(",", $extras);
        }
        $this->request("flickr.photos.getNotInSet", array("extras"=>$extras, "per_page"=>$per_page, "page"=>$page));
        $this->parse_response();
        $result = $this->parsed_response['rsp']["photos"];
        if (!empty($result['photo']['id'])) {
            $tmp = $result['photo'];
            unset($result['photo']);
            $result['photo'][] = $tmp;
        }
        return $result;
    }
