Question

我有十个问题和答案。我使用arry_rand和shuffle随机分配问题，并随机整理答案。我如何确保只问一次问题。在浏览完所有十个问题后，我希望游戏结束。谢谢您的帮助！：）这是我到目前为止所拥有的。

 include ("inc/questions.php");
 session_start();

$pageTitle = "Math Quiz: Addition";

$_SESSION["score"]= 0;
if ((isset($_SESSION["score"]) && $choices[0]["correctAnswer"])){
   $_SESSION["score"] += 1;
}
echo $_SESSION["score"];

$rand = array_rand($questions,1);
shuffle($questions);

$choices = [
  $questions[0]["correctAnswer"],
  $questions[0]["firstIncorrectAnswer"],
  $questions[0]["secondIncorrectAnswer"],
];
shuffle($choices);


if ((!isset($_SESSION["counter"]) || $_SESSION["counter"] >9)){
  $_SESSION["counter"] = 1;
} else {
    $_SESSION["counter"] += 1;
}

Answer 1

您可以通过在每个会话中仅对问题进行一次改组，并将经过改组的版本保留在会话变量中来实现此目的，每次弹出一个问题。

其他一些问题：

您将每次时间的得分重置为零。
要检查用户提交的答案是否正确，您需要查看$_POST[]数组

您可以使用以下代码：

// Check submitted answer is correct:
if (isset($_SESSION["correctAnswer"]) && isset($_POST[$_SESSION["correctAnswer"]])) {
    $_SESSION["score"] += 1;
}

if (!isset($_SESSION["score"]) {
    $_SESSION["score"] = 0;
    $_SESSION["counter"] = 0;
    shuffle($questions);
    $_SESSION["questions"] = $questions;
}

echo "score = " . $_SESSION["score"];

if (count($_SESSION["questions"]) == 0) {
    // Here you should navigate to a game-over page that 
    // displays the score and allows to start again (clearing the session).
    die ("No more questions");
}

// Get next question
$currQuestion = array_pop($_SESSION["questions"]);
$_SESSION["correctAnswer"] = $currQuestion["correctAnswer"];

$choices = [
    $currQuestion["correctAnswer"],
    $currQuestion["firstIncorrectAnswer"],
    $currQuestion["secondIncorrectAnswer"],
];
shuffle($choices);

$_SESSION["counter"] += 1;

在其余代码中，将$questions[0]的出现替换为$currQuestion。

Answer 2

代替：

$rand = array_rand($questions,1);
shuffle($questions);

做

<div class="container">
        <div id="quiz-box">
<?php

    shuffle($questions); 
    for($i=0; $i<count($questions); $i++) {
?>
            <p class="breadcrumbs"> <?php echo "Question Number "  . $i . " of " . "10"; ?>
            <p class="quiz"><?php echo "What is " . $questions[$i]["leftAdder"] . " + " . $questions[$i]["rightAdder"];?></p>
            <form action="index.php" method="post">
                <input type="hidden" name="id" value="0"/>
                <input type="submit" class="btn" name="answer1" value="<?php echo $choices[$i][0];?>" />
                <input type="submit" class="btn" name="answer2" value="<?php echo $choices[$i][1];?>" />
                <input type="submit" class="btn" name="answer3" value="<?php echo $choices[$i][2];?>" />
            </form>

        </div>
    </div>
<?php

    }
?>

我正在制作一个PHP测验应用程序。如何确保只问一次问题？
