Your HTML or PHP script comes here ...
Note : you could also use an HTML block for this. And if you want something more advanced, you really should have a look at modules like ContentExpress and EZ CMS.
If you want to use this in some other directory, insert the following line before the first include : chdir('/home/dir/of/your/PostNuke/html') or die("Sorry, this won't work for you. Check your PHP settings regarding safe_mode, doc_root and open_basedir. For more information, see http://www.php.net/manual/en/configuration.php");
