Refresh part of a page

[sirio]

I posted this in the wrong forum of this website, so i repeat:
I'm running my website with php-nuke, n my forums are the well known phpbb forums.
In the main page of my website, i have a script that shows the last topics in the forums... so i wanted to know if it is possible to refresh ONLY that part of the page (and not the parent page) clicking on a link or button. Maybe in php? javascript?...

I've been searching, and i found nothing.

Somebody suggested me to use ajax, but i want a better way to solve this.

Thanks.

You could use an iframe and simply have a refresh link that targets it. Other than that you would probably have to use an http_request and some javascript ("ajax");

ok, i've made an iframe to do it, but i get an error message.

In index.php, i wrote:
<iframe src="foros.php" width="100%" height="200"></iframe>

and when i run the index, i get this:

[quote]Fatal error: Call to a member function on a non-object in /data/members/free/tripod/es/l/a/t/latinquasar/htdocs/foros.php on line 28[/quote]

foros.php is just a block in phpnuke.
