Unable to get x_rate_limit_remaining

[adiospeds]

I was developing a simple function to get the id's of followers. I get the results but I am not able to get the headers info so that I can consider the x_rate_limit_remaining.
The function is :

function get_id_of_followers() {
    $access_token = $_SESSION['access_token'];
    $connection = new TwitterOauth(CONSUMER_KEY, CONSUMER_SECRET, $access_token['oauth_token'], $access_token['oauth_token_secret']);
    $data0 = get_class_methods($connection);
    echo "<pre> D0 ", print_r($data0, true), "</pre>";
    $data1 = $connection->getLastXHeaders();
    echo "<pre> D1 ", print_r($data1, true), "</pre>";
    $data2 = $connection->getLastXHeaders()["x_rate_limit_remaining"];
    echo "<pre> D2 ", $data2, "</pre>";
    $data3 = $connection->get('followers/ids');
    echo "<pre> D3 ", print_r($data3, true), "</pre>";
}

The Output from the function is as follows:

 D0
Array
(
    [0] => __construct
    [1] => setOauthToken
    [2] => getLastApiPath
    [3] => getLastHttpCode
    [4] => getLastXHeaders
    [5] => getLastBody
    [6] => resetLastResponse
    [7] => url
    [8] => oauth
    [9] => oauth2
    [10] => get
    [11] => post
    [12] => delete
    [13] => put
    [14] => upload
    [15] => setTimeouts
    [16] => setDecodeJsonAsArray
    [17] => setUserAgent
    [18] => setProxy
    [19] => setGzipEncoding
)


D1 
Array
(
)


 D2 

D3 
stdClass Object
(
    [ids] => Array
        (
            [0] => 730017479360045056
            [1] => 4716372642
            [2] => 709411090980020224
            [3] => 4905437529
            [4] => 709964576868200449
            [5] => 228648311
            [6] => 3190604329
            [7] => 4298659035
            [8] => 378112124
            [9] => 4554579372
            [10] => 3845238492
            [11] => 3009354738
records retrived upto 5000

Now I am able to get the response(D3) however, Why is my headers(D2) array returning as null ?

You're code works fine for me.

<pre> D1 Array
(
    [x_access_level] => read-write
    [x_connection_hash] => 243162748c890e36060589705b4f6450
    [x_content_type_options] => nosniff
    [x_frame_options] => SAMEORIGIN
    [x_rate_limit_limit] => 15
    [x_rate_limit_remaining] => 14
    [x_rate_limit_reset] => 1463852701
    [x_response_time] => 119
    [x_transaction] => fa0b0434dbff3960
    [x_twitter_response_tags] => BouncerCompliant
    [x_xss_protection] => 1; mode=block
)
</pre>
<pre> D2 14</pre>
