not sure if this is a website problem really, but this page:

    http://www.php.net/manual/en/migration.truefalse.php

shows:

$fp = fopen($file, "r");
if ($fp == -1);
    echo("Could not open $file for reading<br>\n");
endif;
]]|
    </programlisting>
   </example>
   <example>
    <title>Migration from 2.0: return values, new code</title>
    <programlisting role="php">
<![CDATA[
$fp = @fopen($file, "r") or print("Could not open $file for reading<br>\n");


as example d-9. I assume that's not meant to show the xml there.
