  <p>This one works.</p>
  
  <pre><code>  &lt;article class='nobackground'&gt;
      &lt;iframe src='http://en.wikipedia.org/wiki/&lt;?php echo $myid ?&gt;'&gt;&lt;/iframe&gt;
    &lt;/article&gt;
  </code></pre>
  
  <p>This one does not display. (neither will youtube, google or facebook, however static html seems to display fine)</p>
  
  <pre><code>   &lt;article class='nobackground'&gt;
      &lt;iframe src='http://www.google.ie/search?tbm=isch&amp;hl=en&amp;source=hp&amp;biw=1280&amp;bih=679&amp;q=&lt;?php echo $myid ?&gt;'&gt;&lt;/iframe&gt;
    &lt;/article&gt;
  </code></pre>
