title: How to prevent outputing the html label?
body: <p>The code I currently have is:</p>
  
  <pre><code>&lt;h2 id="comment_title"&gt;vistor comments&lt;/h2&gt;  
  &lt;div class="count"&gt;
    &lt;?php 
      $count = comment_num($nid);
      if($count&gt;0){
          echo $count'comments';
      } else {
          echo '';        
      }
    ?&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Now, i want to know how to alter the above code to get this effect:</p>
  
  <p>When <code>$count &gt; 0</code>, it should output the html label, and can use some css style to it.  </p>
  
  <pre><code>&lt;h2 id="comment_title"&gt;vistor comments&lt;/h2&gt;and $count'comments';
  </code></pre>
  
  <p>When <code>$count &lt;= 0</code>, don't output the html label. and don't use any css style to it.</p>
  
  <pre><code>&lt;h2 id="comment_title"&gt;vistor comments&lt;/h2&gt; ;
  </code></pre>
