I have a function that gets friends and followers of a twitter account. I'm making a "Who's Not Following back app" How do I filter the xml/json data (I can use both) ie to echo what is in following but not in followers.
Here's my code
function twitter_notf_page($query) {
$user = $query[1];
if (!$user) {
user_ensure_authenticated();
$user = user_current_username();
}
$request = API_URL."statuses/friends/{$user}.xml";
$tla = lists_paginatedd_process($request);
$request = API_URL."statuses/followers/{$user}.xml";
$tl = lists_paginatedd_process($request);
$content = "<h2>FRIENDS</h2>";
$content .= theme('notf', $tla);
$content.="<br><hr>";
$content .= "<h2>FOLLOWERS</h2>";
$content .= theme('notf', $tl);
theme('page', 'Followers', $content);
}
function lists_paginatedd_process($url) {
// Adds cursor/pagination parameters to a query
$cursor = $_GET['cursor'];
if (!is_numeric($cursor)) {
$cursor = -1;
}
$url .= '?cursor='.$cursor;
$xml = twitter_process($url);
$ret = simplexml_load_string($xml)
return $ret;
}
Results - Following
