php foreach循环帮助

Question

I have a foreach loop that builds me a product page basically it out puts my products in rows of 3.

See the code:

foreach ($product_sets as $product)
{
    $currentRow = ceil($currentItem / 3);
    $currentColumn = $currentItem - (($currentRow - 1) * 3);
    if ($number_of_blanks == 2) :
        if (($number_of_rows > 1 && $currentRow == ($number_of_rows - 1) && $currentColumn == 2) || ($number_of_rows == 1 && $currentColumn == 1)) :
    ?>
            <li><img src="<?php echo site_url('assets/img/blocks/guarantee.png'); ?>" alt="5 Year Guarantee" width="242" height="156"></li>
    <?php
            $currentItem++;
        endif;
    endif;
    ?>
    <li class="<?php if($currentItem % 3 == 0) echo 'endHomeBlock';?>">
        <?php $this->load->view('blocks/product_small', array('product' => $product)); ?>
    </li>
    <?php
        $currentItem++;

    }

What I am wanting be able to do is place an image (A point of sale) at the end of the first row, and the randomly through the other rows, but maintaining 3 items (including image a point of sale) on a row. I have the image paths in an array called images which looks similar to this,

$images = array(
  'iamge1.png',
  'image2.png,
  'image3.png,
  'image4.png,
);

How can I achieve this? I have been scrathing around for a few hours now :(

Sorry I don't have much time in writing you the full code, but the following should work:

<ul>
    <li><?php
        foreach($items as $i=>$item){
            // ...write item...
            if(($i % 3)==0 && $i!=0){ // if multiple of 3 and not the first time..
                ?></li><li><?php
            }
        }
    ?></li>
</ul>
