WHILE 中的 PHP 数组

Question

我有这段代码:

<?php
$counter = 0;
while ($row = mysql_fetch_array($bim_coupons_price)){?>
    <div class="clone">
        <div id="start_date_countdown">
            <span>No</span>
            <input id="start_datetimepicker<?php echo $counter?>" type="text" name="start_date_countdown[]" value="<?php if(isset($_POST['start_date_countdown'][0])){echo $_POST['start_date_countdown'][0];}else{echo $row['start_date_countdown'];}?>"/>
        </div>  
        <div id="end_date_countdown">
            <span>Līdz</span>
            <input id="end_datetimepicker<?php echo $counter?>" type="text" name="end_date_countdown[]" value="<?php if(isset($_POST['end_date_countdown'][0])){echo $_POST['end_date_countdown'][0];}else{echo $row['end_date_countdown'];}?>"/>
        </div>
        <div id="price_container">
            <span>Cena</span>
            <input type="text" id="price_new" name="price_new[]" value="<?php echo $row['price_new']?>"/>
        </div>
    </div>
    <div style="clear:both;"></div>
<?php $counter++; } ?>

问题是这个 while 循环将执行 3 次，我每次都需要将 $_POST['start_date_countdown'][0]) 更改为 $_POST['start_date_countdown'] [1])、$_POST['start_date_countdown'][2]) 等...

我怎样才能做到这一点？

只需将 $_POST['INDEX_KEY'][0] 更改为 $_POST['INDEX_KEY'][$counter]。 INDEX_KEY 属于 start_date_countdown 和 end_date_countdown
