    if(strpos($page, './') !== false

Hi

Im thinking about learning php, so if you dont mind me asking what does the code above actualy do?

The code above is processing some page defined in a php file as $_GET['page'] or as it would appear in a browser address bar

http://www.dynamicdrive.com/index.php?page=_page_

If the file is in the correct format, the page / file will be brought into (included) the php file, if not, an error page will be included.
