將會話存儲為關聯數組

Question

有沒有一種方法可以將SESSION名稱存儲為associative數組？

我在下面進行此會話，單擊單選按鈕后即可通過ajax進行設置。

$question = span name wherein question is displaying 
$answer = radio button value
$_SESSION['$question'] = "answer";

然后，我想將其轉換為以下內容，我想保留會話變量名稱作為鍵。

$QandA = array (question1 => asnwer1, question2 => asnwer2, question3 => asnwer3 );

如果我喜歡這樣並執行vardump ，它將成為indexed數組

$QandA = array ($_SESSION['$question']);

不知道將什么作為關鍵。

  $QandA = array ("what should be here to get session variable name as key"  => $_SESSION['$question']);

Answer 1

就在這里。 但是我建議您像這樣使用它。 每一個問題是一個數組，什么有question和answer的關鍵。

$_SESSION['question1'] = array(
    'question' => 'The question',
    'answer1' => "the answer"
    'answer2' => "other answer",
    'answer3' => "more answer",
);
$_SESSION['question2'] = array(
    'question' => 'Another question',
    'answer1' => "Answer for the other question."
);

//First question
echo $_SESSION["question1"]['question'];
//Answers for the question
echo $_SESSION["question1"]['answer1'];
echo $_SESSION["question1"]['answer2'];
echo $_SESSION["question1"]['answer3'];

//Second question
echo $_SESSION["question2"]['question'];
//Answer for second question
echo $_SESSION["question2"]['answer1'];

Answer 2

為什么不只將所有答案存儲為單個會話密鑰中的關聯數組？

$_SESSION['question_answers'] = array(
    $question1 => $answer1,
    $question2 => $answer2,
    // etc etc    
);

然后，您可以根據需要將每個單獨的請求添加到其中

$_SESSION['question_answers'][$question3] = $answer3;

等等等等。
