Php 我想将数组值存储在会话变量中。并在下一页中检索这些值

我正在开发一个测验应用程序php。我想将测验数据和用户选择的选项合计到下一页。我想在使用时单击摘要按钮显示测验摘要。请帮助我如何执行此操作

<?php   

          require 'dataconnection.php';

          $res = mysql_query("select * from questions where category_id=$category ORDER BY RAND() LIMIT 20") or die(mysql_error());
                    $rows = mysql_num_rows($res);


          echo $rows;
          $i=1;
           while($result=mysql_fetch_array($res)){


               if($i==1){?>
                       <div id='question<?php echo $i;?>' class='cont'>

                    <p class='questions' id="qname<?php echo $i;?>"> <?php echo $i?>.<?php echo $result['Question'];?></p>

          <?php } $i++;  $_SESSION['Questions']['']= $result;

                    ;
                      } 
          ?>

在此页面中，将会话另存为json

$_SESSION['Questions'] = json_encode(mysql_fetch_assoc($res));

在页面中，解码json

$questions = json_decode($_SESSION['Questions']);

注意：尝试使用mysqli或PDO您使用的语法已被弃用，将从未来的php版本中删除

您需要格式化代码。每行必须至少缩进4个空格，才能被解释为代码-突出显示它并点击ctrl-K将给您一个良好的开始。但它只给出数组的最后一个值，您可以提供一个变量转储

json\u encode（mysql\u fetch\u assoc（$res））它正在工作。我构建测验应用程序。我想将所选单选按钮值显示到下一页，并将这些值显示为用户过去的选择以及问题的正确答案。请帮助如何操作
