title: php problem not sure what is wrong
body: <p>I am learning PHP and copied this piece of code from the book.</p>
  
  <pre><code>&lt;?php
   require_once('bookmark_fns.php');
   do_html_header('');
  
   display_site_info(); 
   display_login_form();
  
   do_html_footer();
  ?&gt;
  </code></pre>
  
  <p>I am running it in IE and I get The website cannot display the page message.
  I tried echo"hello"; and that worked fine.  Any ideas of why this would not work. I wish I could give more detail, but am still unfamilair with PHP</p>
