Q: 

Echo can you hear me?

Why is showphp_Smartfm() Not echoing at all.

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

A: 

Enable all the error reportings:

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

and try with:

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

and see what is going on

foreach($response->quizzes as $quiz) { var_dump($quiz->question); // question var_dump($quiz->answer); // answer }Nothing and foreach($response->quizzes as $quiz) { echo var_dump($quiz->question); // question echo var_dump($quiz->answer); // answer }nothingI believe I have error reporting on? how do i make sure?

Nothing at all for the above, how do I make sure i have error reporting on?
Klanestro  2010-01-22 14:45:07
Updqated my answer.
DaNieL  2010-01-22 14:50:33
still nothing ★✩ there is info in the json file regarding someone elses comment

A: 

Start doing 'echo-debugging'. 

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

foreach($response->quizzes as $quiz)
    {
      echo $quiz->question; // question
      echo $quiz->answer; // answer
    }
  1. Maybe there are no $response->quizzes
  2. Maybe the question and answer are empty string
  3. Maybe this code is never being reached
  4. Maybe it's outputting inside an HTML tag and you never thought to check View Source
  5. Maybe it's dying way earlier in the script and you don't have error reporting turned on.

1-2.There is information in $response->quizzes in the json file; see http://stackoverflow.com/questions/2116963/navigating-objects-and-arrays 3. The code is going all the way through I know because it echo's at the very end, 4. I live in view source5 don't think so, I see my errors I did turn it on when I installed it.
