Question

我目前正在使用NewYorkTimes新闻API。我收到了这个JSON响应。现在我想使用PHP遍历它并获取每篇文章（图像，标题和摘录）。

}

首先，我使用$arr = json_decode($result);来解码我的json。但是当我试图制作一个循环时，它并没有给我任何回报

foreach($arr['docs'] as $article){
    echo $article['web_url'];
}

请帮我循环查看此JSON响应并获取必要的数据。谢谢！

试试这个

$json = json_decode($response, true);
foreach($json['response']['docs'] as $key => $value)
{
  if(!empty($value['web_url']))
  {
   $WEB= $value['web_url'];
   $WEB= addslashes($WEB);
   $WEB= trim(preg_replace('/\s\s+/', ' ', $WEB));
  }
  else
  {
    $WEB= '';
  }
   echo 'WEB= '.$WEB.'</br>';
}

只要确保foreach是真的，也许可以提供帮助。
