Components + scripts

[Connie]

A very interesting siutation came up in a post in the "german corner" and needs some clearance.

See here: http://get-simple.info/forums/showthread...n=lastpost

The question was how to include a script in a component:

PHP Code:

<?php include('shoutbox/shoutbox.inc.php'); ?>

brings error: "You don't have permission to access /admin/components.php on this server."

PHP Code:

<?php include_once('shoutbox/shoutbox.inc.php'); ?>

works. So we have the question: what is the difference between "include" and "include_once" concerning the permissions?

Can somebody enlighten us?
