how to get all available user search records from twitter API using laravel

i am working on twitter API https://api.twitter.com/1.1/users/search.json when i request for a user records using GET request i am getting just first page of records in json first 20 records but i want all records of any specific name which i enter how to extend the request and store them in database

 public function getTwitter() {
    $settings = array(
        'oauth_access_token' => "xxxxxxxxxxxxxx",
        'oauth_access_token_secret' => "xxxxxxxxxxxxxxxx",
        'consumer_key' => "xxxxxxxxxxxxxxxxxxxxx",
        'consumer_secret' => "xxxxxxxxxxxxxxxxxxxxxxx"

    );





            $url = 'https://api.twitter.com/1.1/users/search.json';
            $getfield = '?q=name to search';
            $requestMethod = 'GET';

            $twitter = new TwitterAPIExchange($settings);
            $users =  $twitter->setGetfield($getfield)
                ->buildOauth($url, $requestMethod)
                ->performRequest();

            $users = json_decode($users,true);
           // var_dump($users);die();
              for($i=0;$i<=19;$i++)
            {
                $twitter=new twitter_user();
                $twitter->user_id=$users[$i]['id'];
                $twitter->name=$users[$i]['name'];
                $twitter->sname=$users[$i]['screen_name'];
                $twitter->location=$users[$i]['location'];
                $twitter->save();

            }    

            echo "Data saved";

i am using this for loop till 19 because its giving me 20 records i want to access all available records dynamically
