每3个foreach添加一个清除div

Question

I want to add a clear div (that is, <div class="clear></div> ) after every 3rd term, but I am having difficulties doing this within a foreach block. I can, however, within a while loop.

Any help is greatly appreciated.

<?php 

$terms = get_field('feature_choices');
// print_r($terms);
if( $terms ): ?>

<?php foreach( $terms as $term ): ?>

    <div class="col-sm-3 margin_bottom">
        <div class="row">
            <div class="col-xs-2">
                <img src="<?php bloginfo('template_directory'); ?>/assets/img/checkmark.png" alt="" />
            </div>
            <div class="col-xs-10">
                <?php echo $term->name; ?>
            </div>
        </div>
    </div>

<?php endforeach; ?>
<?php endif; ?>

add a counter

<?php $count = 1; foreach( $terms as $term ): ?>

    <div class="col-sm-3 margin_bottom">
        <div class="row">
            <div class="col-xs-2">
                <img src="<?php bloginfo('template_directory'); ?>/assets/img/checkmark.png" alt="" />
            </div>
            <div class="col-xs-10">
                <?php echo $term->name; ?>
            </div>
        </div>
    </div>
<?php if( $count % 3 == 0 ) echo "\n".'<div class="clear"></div>'; ?>
<?php $count++; endforeach; ?>
<?php endif; ?>
