Iterating through array in PHP for Yahoo API

Question

I am trying to return all of the answers to each question from the Yahoo API and right now my code is...

    $appid= "myid";
    $params = array(
'query'     =>      $keyword,   //enter your keyword here. this will be searched on yahoo answer
'results'   =>      $maxLimit,         //number of questions it should return
'type'      =>      'resolved',  //only resolved questiosn will be returned. other values can be all, open, undecided
'output'    =>      'php',      //result will be PHP array. Other values can be xml, json, rss
);
$yn = new yahooAnswer($appid);
//search questions
try
{
    $questions = $yn->search_questions($params);
} catch (Exception $e)
{
    echo ($e->getMessage());
}

foreach ($questions as $question) 
{
//now get the answers for the question_id;
    try
    {
        $answers = $yn->get_question(array('question_id'=>$question['id']));
        //print out what you would like...All fields are location on this site http://developer.yahoo.com/answers/V1/getQuestion.html
        print_r($answers);

        //print_r( $answers['NumAnswer']);
        //print_r( $answers['Content'] . "<br/>");

        //print_r($answers['chosenanswer'] . "<br/>");
        //echo $answers['UserNick']. "<br />";

        echo "<hr>";
    } catch (Exception $e)
    {
        echo($e->getMessage());
    }

}

and I get this as the return when I print_r($answers)...

    )

)

But when I use print_r(answers['Content']) I only get one of them printed, not all of them. Any ideas on how to go about this issue? There should be six answers being printed

Answer 1

Thats because the array contains a new Array of answers called ['Answers']. So if you want to print each answer you get, you will have to do the following:

try
{
    $answers = $yn->get_question(array('question_id'=>$question['id']));
    //print out what you would like...All fields are location on this site http://developer.yahoo.com/answers/V1/getQuestion.html
    foreach($answers['Answers'] as $answer)
    {
      print_r($answer['Content']);
      echo "<hr>";
    }
}
catch (Exception $e)
{
    echo($e->getMessage());
}

E: When you dump an array with print_r() or var_dump(), alsways wrap up the result in pretags so you can easily see what's nested inside an new array etc.

echo "<pre>";
print_r($answers);
echo "</pre>";
