题号递增的实现

题号递增的实现

我想让每个问题编号从1开始。目前，问题编号是基于它们在数据库中的相应编号。我怎样才能让它从1开始？

<body>

<div class="container">

<h1> Quiz</h1>

<?php echo form_open('user/resultdisplay/', ['class' =>'form-horizontal']);?>

<?php if(count($questions) > 0):?>

<?php foreach($questions as $row):?>

<p><?=$row->ch_id?>. <b><?=$row->ques?></b></p>

<input type="radio" name="ch_id<?=$row->ch_id?>" value="<?=$row->ch_des1?>"> <?=$row->ch_des1?><br>

<input type="radio" name="ch_id<?=$row->ch_id?>" value="<?=$row->ch_des2?>"> <?=$row->ch_des2?><br>

<input type="radio" name="ch_id<?=$row->ch_id?>" value="<?=$row->ch_des3?>"> <?=$row->ch_des3?><br>

<input type="radio" name="ch_id<?=$row->ch_id?>" value="<?=$row->ch_des4?>"> <?=$row->ch_des4?><br>

<?php endforeach;?>

<?php else:?>

<tr>

<td>No records found!</td>

</tr>

<?php endif;?>

</body>

<input type="submit" value="Submit!">

</form>

</div>

</body>

添加一个计数器并手动增加它：<?php if(count($questions) > 0):?>    <?php $index = 1; ?>    <?php foreach($questions as $row):?>    <p><?=$index++?>. <b><?=$row->ques?></b></p>    <input type="radio" name="ch_id<?=$row->ch_id?>" value="<?=$row->ch_des1?>"> <?=$row->ch_des1?><br>    <input type="radio" name="ch_id<?=$row->ch_id?>" value="<?=$row->ch_des2?>"> <?=$row->ch_des2?><br>    <input type="radio" name="ch_id<?=$row->ch_id?>" value="<?=$row->ch_des3?>"> <?=$row->ch_des3?><br>    <input type="radio" name="ch_id<?=$row->ch_id?>" value="<?=$row->ch_des4?>"> <?=$row->ch_des4?><br>     <?php endforeach;?><?php else:?>        <tr>            <td>No records found!</td>        </tr><?php endif;?>
