  <pre><code>&lt;?php echo $this-&gt;Html-&gt;link(
     $this-&gt;Html-&gt;tag('i', '', array('class' =&gt; 'glyphicon glyphicon-edit')) . " Edit",
     array('action' =&gt; 'edit', $comment['Comment']['comment_id']),

  <p>It gives me <code>&lt;i class="glyphicon glyphicon-remove"&gt;&lt;/i&gt; Delete</code></p>
