推特 api 无法在 php 中使用 foreach 循环

Question

我无法让 foreach 循环显示来自 Twitter 的任何数据api

请看下面的代码。但是，它确实在 print_r 数组上显示数据。

提前感谢您抽出时间

     ini_set('display_errors', 1);
     require_once('TwitterAPIExchange.php');

 /** Set access tokens here - see: https://dev.twitter.com/apps/ **/
  $settings = array(
      'oauth_access_token' => "*******",
       'oauth_access_token_secret' => "*******",
       'consumer_key' => "********",
       'consumer_secret' => "*******"
      );


       /** Perform a GET request and echo the response **/
       /** Note: Set the GET field BEFORE calling buildOauth(); **/
       $url = 'https://api.twitter.com/1.1/search/tweets.json';
        $getfield = '?q=love+you&count=20';
        $requestMethod = 'GET';
        $twitter = new TwitterAPIExchange($settings);
        $string = json_decode($twitter->setGetfield($getfield)
         ->buildOauth($url, $requestMethod)
         ->performRequest(),$assoc = TRUE);
        if($string["errors"][0]["message"] != "") {echo "<h3>Sorry, there 
          was a problem.</h3><p>Twitter returned the following error 
       message:</p><p><em>".$string[errors][0]["message"]."
       </em></p>";exit();}


    foreach($string as $tweets) {

      echo $tweets['name'] . '<br />';

    }

    cannot get the foreach loop to display any data from the twitter api

所以首先你遍历了错误的数组。您要查找的数组在 statuses 索引下，因此将循环更改为：

foreach($string['statuses'] as $tweets) {
    echo $tweets['name'] . '<br />';
}

看看你的 print_r() 并仔细检查子数组是如何构建的。例如。如果您想打印每个推文作者的姓名，您应该将 foreach 中的 echo 修改为：

echo $tweets['user']['name'] . '<br />';

因为输出数组有结构

array(..., 'user' => array('name' => 'Example name', ...));
