Php Json获得第一个元素信息

Question

所以我使用PHP Twitter API来获取带有特定主题标签的推文列表。我希望从返回的json中获取以下信息; ＆＃39; SCREEN_NAME＆＃39;和＆＃39;文字＆＃39;。

screen_name位于第44行，文本位于第20行。

这是json输出。

      string(2) "en"
    }
}

这是我的PHP代码

<?php
require_once 'twitteroauth/twitteroauth.php';

define('CONSUMER_KEY', '');
define('CONSUMER_SECRET', '');
define('ACCESS_TOKEN', '-');
define('ACCESS_TOKEN_SECRET', '');

$toa = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET);

$query = array(
  "q" => "#nerd",
  "result_type" => "recent"
);

$results = $toa->get('search/tweets', $query);

var_dump($results); die();

foreach ($results->statuses as $result) {
  echo $result->user->screen_name . ": " . $result->text . "<br>";
}

非常感谢！我已经尝试了一段时间，需要一些指向正确的方向：）
