如何输出列表的反转

Question

I have the following piece of code and I would like to display it in the reversed order:

                <div id="gallery-1" class="royalSlider rsDefault visibleNearby">


            <?php
            $current_item = 1;
            $imgID = 1;

            foreach( $cats as $key => $item ){

            if( !empty($cat_id) && $cat_id == $item->id ){
                $current_item = $key+1;
            }?>

              <img class="rsImg" src="<?php echo cmMedia::getOriginalUrl($item->media_id);?>" id="imgID<?php echo $imgID; ?>" />
              <a class="rsImg" href="<?php echo cmMedia::getOriginalUrl($item->media_id);?>" id="imgID<?php echo $imgID; ?>" /></a>

            <?php $imgID++; }?>



            </div>

the output is a slider with 26 slides.

I tried flipping the + with - and starting the variables from 26 to 1 but it didn't work :/

Thx in advance!

I think you are looking for array_reverse? http://php.net/manual/en/function.array-reverse.php

<?php
  $current_item = 1;
  $imgID = 1;
  $cats = array_reverse($cats);
  //... the rest should be the same as you have
