Format output to lowercase

问题

I need to change the output of <?php echo $EM_Category->name; ?> to lowercase only.

Output now is Entertainment. How would I get it to entertainment

Full section of code is:

<?php foreach(EM_Categories::get(array('orderby'=>'category_name')) as $EM_Category): ?>
<a href="<?php echo THEME_URL; ?>/events/category/<?php echo $EM_Category->name; ?>" class="browse-cat">
   <span><?php echo $EM_Category->name; ?></span><img src="<?php echo THEME_URL; ?>/images/box_arrow.png" alt="arrow" height="15" width="15">
</a>
<?php endforeach; ?>
