Twitter get followers/ids curosr not working - twitter

Question

I am trying to get the complete list of follower IDs for a twitter user. This user has 170,000+ followers. I am using the code bird library. Here's the code:
\Codebird\Codebird::setConsumerKey(TWITTER_CONSUMER_KEY, TWITTER_CONSUMER_SECRET);
$cb = \Codebird\Codebird::getInstance();
$cb->setToken(OAUTH_TOKEN, OAUTH_SECRET);
$cb->setReturnFormat(CODEBIRD_RETURNFORMAT_ARRAY);
$next_cursor = -1;
while ($next_cursor) {
$results = $cb->followers_ids("screen_name=some_tw_name","count=5000","cursor=$next_cursor");
$next_cursor = $results['next_cursor_str'];
}
The first call returns 5000 IDs, as it's supposed to. Subsequent calls (through the while loop) return 5000 IDs, but they are almost all the same as the previous call (each new call I get 1 to about 10 news IDs, with the remainder the same as before).
Anyone else run into this issue? resolution?

I think the problem is that you're not really combining the results from each of the requests. so you could do something like this:
function getFollowers(){
$next_cursor = -1;
$output = array();
while ($next_cursor) {
$results = $cb->followers_ids(array("screen_name"=>"some_tw_name","count"=>5000,"cursor"=>$next_cursor));
if(!isset($results['errors'])){
foreach($results['ids'] as $id){
$output[]=$id;
}
}
$next_cursor = $results['next_cursor_str'];
}
return $output;
}
Note: I also changed the argument notation to an array as opposed to strings.
