列出 JSON 响应 PHP 中的值
我目前正在使用 Amazon AWS SNS 向客户发送 SMS。
我想简单地显示一个下拉菜单，topicArn每个选项都作为每个选项。
我从我收到的回复中尝试了以下内容，var_dump($topics);但它不起作用。
<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>
回复：
object(Aws\Result)#109(2){
[
"data": "Aws\Result": private
]=>array(2){
[
"Topics"
]=>array(4){
[
0
