推特json格式在php

我是PHP新手。我在twitter api中创建了一个帐户，并设法以JSON格式从twitter获取数据，并想从JSON中提取文本和created_at字段，但即使在3天后也没有运气，最后的手段是这个地方。

我现在的代码:

$tweets = $connection->get("https://api.twitter.com/1.1/search/tweets.json?q=verizon");
$encode =json_encode($tweets);
$decode = json_decode($encode,true);
foreach($decode as $tweet)
{
  echo "{$tweet->text} {$tweet->created_at}'n";
}

var_dump结果:

    object(stdClass)[34]
      public 'metadata' => 
        object(stdClass)[35]
          ...
