php problem not sure what is wrong
<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>
