To show two divs in one li within loop you can do so,define a flag variable and increment it for each iteration of loop and check if the modulus of flag with 2 is zero i.e $index % 2 == 0 then close li and open li
<ul class="slides">
<li>
<?php
$index = 0;
foreach ($projlists as $projlist) {
?>
<div class="span3">
<a class="thumbnail" href="#">
<img alt="260x180" data-src="holder.js/260x180" style="width: 260px; height: 180px;"
src="<?= base_url() ?>uploads/portfolio/full/<?= $projlist->portfolio_image ?>">
</a></div>
<?php $index++;
if ($index % 2 == 0 && $index !=count($projlists)) {
echo '</li><li>';
}
} ?>
</li>
</ul>
