    <ul id="tag" data-tid="<?php echo $tid; ?>">
        <?php foreach ($list as $k): ?>
            <li data-tag="<?php echo $k['tagid'] ?>"><a href='<?php echo url("tag-$k[tagid]") ?>'><i class="icon-tag"></i><?php echo $k['name'] ?></a></li>
        <?php endforeach; ?>
    </ul>

改成：

    <ul id="tag" data-tid="<?php echo $tid; ?>">
     <?php if (!empty($list)): ?>   
     <?php foreach ($list as $k): ?>
            <li data-tag="<?php echo $k['tagid'] ?>"><a href='<?php echo url("tag-$k[tagid]") ?>'><i class="icon-tag"></i><?php echo $k['name'] ?></a></li>
        <?php endforeach; ?>
        <?php endif; ?>
    </ul>
