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;?>
