Twitter API - Same cursor error - php

Question

From REST API of twitter I user get/followers function.
I pasted a code snippet below.
My problem is, modt of the time I get followers' ids successfully. But when a user has more than 5000-6000 followers then my results comes wrong.
When I check from user's profile page, I see that user has 5500 followers, but when I run following code, most of the time 5500 ids come, but sometimes 29994 followers come inside $ids variable. Now I'm logging the results having more then 29k followers. I saw some of the requests returned with 29994 followers, but I couldn't find the answer.
Do I miss something in get ids - cursor approach? Thank you
Edit: After some debugging I logged "$cursor_archieve" parameter and found out this:
* Sometimes next_cursor and previous_cursor comes same:
Array
(
[0] => -1
[1] => 1400573121087317741
[2] => 1400573121087317741
[3] => 1400573121087317741
[4] => 1400573121087317741
[5] => 1400573121087317741
[6] => 1400573121087317741
)
So in this situation, although user has 7100 followers I get only 5000 followers
Sometimes cursors come sequentially same:
Array
(
[0] => -1
[1] => 1404335879106773348
[2] => 1404341060469987526
[3] => 1404338682006540390
[4] => 1404341060469987526
[5] => 1404335879106773348
[6] => 1404338682006540390
)
My code is like this:
public function getIds($user = "someuser"){
$tmhOAuth = new tmhOAuth(array( 'consumer_key' => YOUR_CONSUMER_KEY,
'consumer_secret' => YOUR_CONSUMER_SECRET,
'user_token' => $atoken1, 'user_secret' => $atoken2, ));
$cursor = '-1';
$ids = array();
$cursor_archieve = array();
while(true):
$code=$tmhOAuth->request('GET', $tmhOAuth->url('1/followers/ids'),
array('screen_name' => $user, 'cursor' => $cursor));
if ($code == 200) {
$responseData = json_decode($tmhOAuth->response['response'],true);
$ids = array_merge($ids, $responseData['ids']);
$cursor = $responseData['next_cursor_str'];
$cursor_archieve[] = $cursor;
} else {
return 0;
}
if ( $cursor == '0' || count($ids) >= 29000 ) {
break;
}
endwhile;
return $ids;
}
edit2: Should I make "array_unique" to delete duplicate ids, or doesn't use next cursor if previous_cursor=next cursor or any other option?
In every case user has 5500-6500 followers. So If I take only one cursor, I only can get first 5000 followers.

Answer 1

The reason was a programatic error in my codes. I fixed it after a week's debug session
