Question

在这个简单的测验中我如何保持得分。我有一些问题和答案。我将答案放在另一个数组中以对其进行随机排序。现在，我不知道如何访问“ correctAnswer”以保持得分。因为在我进行校对时，正确答案在另一个数组中，所以答案出现在答案1，答案2和答案3上，而不是正确答案，firstIncorrectAnswer和secondIncorrectAnswer。这是我的数组和代码。

    <!DOCTYPE html>
<?php
 include ("inc/questions.php");
 session_start();

$pageTitle = "Math Quiz: Addition";

// if (isset($_SESSION["correctAnswer"]) && isset($_POST[$_SESSION["correctAnswer"]])) {
//     $_SESSION["score"] += 1;

// if (!isset($_SESSION["score"])) {
//     $_SESSION["score"] = 0;

if(!$_SESSION) {
  shuffle($questions);
  $_SESSION['questions'] = $questions;
}


if ((!isset($_SESSION["counter"]) || $_SESSION["counter"] >9)){

  $_SESSION["counter"] = 1;

} else {
    $_SESSION["counter"] += 1;
}

/*need to find something that's == $_SESSION['questions'][$index]["correctAnswer"]*/
$index = $_SESSION["counter"] - 1;

$choices = [
  $_SESSION['questions'][$index]["correctAnswer"],
  $_SESSION['questions'][$index]["firstIncorrectAnswer"],
  $_SESSION['questions'][$index]["secondIncorrectAnswer"],
];
shuffle($choices);

?>
