您可以在会话上存储数组，因此每次运行process.php时，您都可以添加一个带有问题编号和给定答案的数组，这样在resultTable.php中，您就可以从数据库中选择10个问题并与给定答案进行比较
添加到process.php中：
if(!isset($_SESSION['answers'])) {
  $answers = new array();
} else {
  $answers = $_SESSION['answers'];
}

$answers[] = array($_SESSION['RQuestionNumber'], $selected_choice);

$_SESSION['answers'] = $answers;

因此，这段代码所做的是创建一个数组来存储问题和用户给定的答案，并将其保存在会话中，这样您就可以在结果表上循环此数组，并在测验中显示所有问题
PS：这是非常基本的代码，要在问答游戏中使用它，您需要做很多事情，即，您应该检查数组是否不是从以前的运行中设置的
您可以使用会话进行设置

会话的简单语法是：

session_start（）；
$\会话['score']=$数据；

现在，只需像这样启动会话，您就可以在另一个页面上使用$data了

session_start（）；
echo$_会话['score']
要删除数据，应销毁会话
session_destroy();

行$\u会话['RQuestionNumber']process.php
中的code>看起来错误-没有设置值-应该不是$\u SESSION['RQuestionNumber']=$number？先生，我可以获得所有问题的问题编号和用户给出的答案，但如何使用数据库中的这些信息获取问题及其正确选择
