按如下所示使用单选按钮数组

Use array of radio button as follows

<form method="post">
    <?php
    for($i=1;$i<=5;$i++)
    {
        ?>
        <div class="well well-sm well-primary">
            <input type="hidden" name="ques"/>Questions?
        </div>
        <div class="well well-sm">
            <div class="radio">
                <label>
                <input type="radio" name="optradio[<?php echo $i; ?>]" value="a">Option 1</label>
            </div>
            <div class="radio">
                <label>
                <input type="radio" name="optradio[<?php echo $i; ?>]" value="b">Option 2</label>
            </div>
            <div class="radio">
                <label>
                <input type="radio" name="optradio[<?php echo $i; ?>]" value="c">Option 3</label>
            </div>
        </div>
        <?php
    }
    ?>
    <button type="submit" class="btn btn-success" name="submit">Finish</button>
</form>

要访问发布的值，只需使用$_POST['optradio']

To access the posted values, you can simply use $_POST['optradio']

考虑选择5个问题为选项1，选项2，选项3，选项1，选项2 POST['optradio']将给出类似

Considering the selection for 5 questions to be Option 1, Option 2, Option 3, Option 1, Option 2 POST['optradio'] will give array like

数组([1] => a [2] => b [3] => c [4] => a [5] => b)

Array ( [1] => a [2] => b [3] => c [4] => a [5] => b )

要访问此数组中的单个值，可以使用foreach循环，

To access sigle values from this array, you can use foreach loop as,

<?php 
 foreach($_POST['optradio'] as $option_num => $option_val)
    echo $option_num." ".$option_val."<br>";
?>
