下面是我的代码问题。php代码

<?php

$rows = mysql_num_rows($res);

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

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

       </div>
   <?php } $i++;   $_SESSION['questions'][]=$result;
}
?>

我将所有问题存储在会话变量中，并在下一页显示。但我不知道如何获得选中的单选按钮值

Result.php

<?php
session_start();
$_SESSION['questions'];


for($i=0;$i<20;$i++) { ?>
    <div id='questions'  class='container-fluid cont'>

        <p class='questions' id="qname<?php echo $i;?>"> <?php echo $i+1?>.<?php echo $_SESSION['questions'][$i]['Question'];?></p>
        <input type="radio" value="A" id='radio1_<?php echo $result['QNo'];?>' name='<?php echo $_SESSION['questions'][$i]['QNo'];?>'/><?php echo $_SESSION['questions'][$i]['Option A'];?>
        <br/>
        <input type="radio" value="B" id='radio1_<?php echo $result['QNo'];?>' name='<?php echo $_SESSION['questions'][$i]['QNo'];;?>'/><?php echo $_SESSION['questions'][$i]['Option B'];?>
        <br/>
        <input type="radio" value="C" id='radio1_<?php echo $result['QNo'];?>' name='<?php echo $_SESSION['questions'][$i]['QNo'];;?>'/><?php echo $_SESSION['questions'][$i]['Option C'];?>
