每个foreach循环两个项目

Question

Apologies if this has already been asked (I cannot find an answer) but I am using PHP and I am building a slider, but would like two images per slide, not one. So, in theory the foreach() needs to include two per each.

An example of the setup is as follows:

<?php foreach ($page->images as $image) : ?>
    <img src="<?php echo $image->url; ?>"/> 
<?php endforeach; ?>

I was thinking I could do something like a count...

<?php $index = 0; foreach ($page->images as $image) : ?>
    <img src="<?php echo $image->url; ?>"/>
    <?php $index++; ?>
    <?php if ( $index % 2 == 0 && $index !=count($page->images) ) : ?>
    <li></li>
    <?php endif; ?>
<?php endforeach; ?>

But I got a little confused as this would insert something every 2... not include two of whatever the foreach loop is fetching at once.

Hope this makes sense and thanks in advance

Okay, I managed to work this out... hopefully it will help.

<div class="each-slide">
<?php $index = 0; foreach ($page->images as $image) : ?>
    <img src="<?php echo $image->url; ?>"/>
    <?php $index++; ?>
    <?php if ( $index % 2 == 0 && $index !=count($page->images) ) : ?>
        </div><div class="each-slide">
    <?php endif; ?>
<?php endforeach; ?>
</div>
