如何在foreach循环codeigniter中跳过/减去第一个值

Question

This is in my view:

<?php foreach ($serial_items as $k => $v): ?>
    <?php foreach ($v['children'] as $a => $b): ?>
    <li>
        <span class="info-bold" style="font-size:12px;"><?=$b->serial_num?></span>
    </li>
    <?php endforeach; ?> 
<?php endforeach; ?>

Q: how can skip first value in $v ? or I want to start the loop from 2nd up to last item of $v .

Answer 1

Not sure if it will be a good solution or not, but it will work for you.

<?php foreach ($serial_items as $k => $v): ?>
         <?php $counter =0;  foreach ($v['children'] as $a => $b): ?>
              <?php if($counter == 0) continue; //if counter is 0, it means you are at first value of $v array, so skip it and continue the loop ?>
              <li>
                 <span class="info-bold" style="font-size:12px;"><?=$b->serial_num?></span>
              </li>
         <?php $counter++; ?>
         <?php endforeach; ?> 

As you can see i have created a counter variable $counter in the top foreach loop, where its value is 0. Now in the second loop, i check if $counter is equal to 0, if zero, it means i am at first element of $v array, so it skips it and continue to the inner loop by using continue . $counter is incremented with each iteration of inner foreach loop and is set to zero again with each iteration of outer foreach loop.

I hope this will help.

Note: This code i not tested, it is just to give you an idea. It may or may not work. Kindly adjust it according to your needs if you are using it

<?php foreach ($serial_items as $k => $v): ?>
<?php $i=0;?>
<?php foreach ($v['children'] as $a => $b): ?>
 <?php if($i>0){?>
<li>
    <span class="info-bold" style="font-size:12px;"><?=$b->serial_num?></span>
</li>
<?php $++;}?>
<?php endforeach; ?> 
<?php endforeach; ?>
