title: Remove comma on last item of foreach
body: <p>I have next code for WordPress loop of tags for single post:</p>
  
  <pre><code>&lt;?php if ($tags) : foreach($tags as $tag): ?&gt;
  &lt;a href="&lt;?php echo get_tag_link($tag); ?&gt;"&gt;
      &lt;?php echo $tag-&gt;name; ?&gt;
  &lt;/a&gt;, 
  &lt;?php endforeach; endif; ?&gt;
  </code></pre>
  
  <p>I have comma added to last anchor. There is also white space after comma.</p>
  
  <p>How can I remove the comma from last anchor while I am doing this with foreach() PHP loop?</p>
  
  <p>Thanks for ideas and help!</p>
