Question

我目前正在使用Amazon AWS SNS向客户发送短信。

我想简单地显示一个下拉菜单，其中每个topicArn作为每个选项。

我从var_dump($topics);收到的响应中尝试了以下方法，但是它不起作用。

<div class="form-group">
                <label for="exampleFormControlSelect1">Select list</label>
                <select class="form-control" name="selectList" id="selectList">
                   <?php
                    $topics = $sns->listTopics();
                    $test = $topics->get('Topics');
                     foreach($test['TopicArn'] as $topicArns)
                     {
                          echo '<option>'.$topicArns.'</option>';
                     }  
                  ?>
                </select>
              </div>

响应：

    "data": "Aws\Result": private
  ]=>array(2){

      "Topics"

foreach($test['Topics'] as $topic)
{
 echo '<option>'.$topic['TopicArn'].'</option>';
}
