回聲你能聽到我嗎？

爲什麼showphp_Smartfm（）根本沒有回顯。回聲你能聽到我嗎？

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

這個固定

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

啓用所有錯誤reportings：

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

，並嘗試：

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

，看看發生了什麼

的foreach（$響應 - >測驗爲$測驗） { 的var_dump（quiz- $>的問題）; // question var_dump（$ quiz-> answer）; // $ } Nothing和 foreach（$ response-> quizzes as $ quiz） { echo var_dump（$ quiz-> question）; // question echo var_dump（$ quiz-> answer）; // answer } nothing 我相信我有錯誤報告？我如何確定？ – Klanestro 2010-01-22 14:44:21

上述內容完全沒有，我如何確保自己有錯誤報告？ – Klanestro 2010-01-22 14:45:07

更新了我的答案。 – Strae 2010-01-22 14:50:33

開始做'回聲調試'。

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

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

也許沒有$響應 - >測驗
也許這個問題，答案是空字符串
也許永遠不會被達到
這個代碼也許它輸出HTML標籤內，你從來沒有想過檢查查看源代碼
也許它在腳本的早些時候死去，並且你沒有打開錯誤報告。

1-2。json文件中有$ response->測驗中的信息;請參閱http://stackoverflow.com/questions/2116963/navigating-objects-and-arrays 3.代碼是通過我所知道的，因爲它回聲的最後， 4.我住在查看源 5不這麼認爲，我看到我的錯誤，當我安裝它時，我確實打開了它。 – Klanestro 2010-01-22 14:52:58

回聲你能聽到我嗎？
