Question

为什么showphp_Smartfm（）根本不回显。

  foreach($response->quizzes as $quiz)
        {
          echo $quiz->question; // not echoing
          echo $quiz->answer; // not echoing
        }

Answer 1

这解决了它

-    if(!isset($object->quizzes))
0
+    if(!isset($object->responses))

Answer 2

启用所有错误报告：

error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
//or directly edit your php.ini !

并尝试：

foreach($response->quizzes as $quiz)
    {
      var_dump($quiz->question); // question
      var_dump($quiz->answer); // answer
    }

看看发生了什么

Answer 3

开始做'echo-debugging'。

print_r($response); 
print_r($response->quizzes);

foreach($response->quizzes as $quiz)
    {
      echo $quiz->question; // question
      echo $quiz->answer; // answer
    }

也许没有$ response-＆gt;测验
也许问题和答案是空字符串
可能永远无法访问此代码
也许它在HTML标记内输出，你从未想过检查View Source
可能它早在脚本中就已经死了，而且你没有打开错误报告。

Echo你能听到我吗？
