get_meta_tags function.... pls help.

Anon

hi all, regarding the get_meta_tags function in php,

Can you get meta-tags from "http://blahblah.com" instead of from pages in your own site?
Can you just put "http://www.blahblah.com" or do you have to specify the entire path "http://www.blahblah.com/blah.html"
Does the "/" at the end of a path affect it?

I've checked the php.net manual but it doesnt say, so thank you for your help...

<?
$metatags = get_meta_tags("http://www.phpbuilder.com/",1);
echo "$metatags[keywords]";
echo "$metatags[description]";
?>

Should work just fine...

Sorry, but it doesn't work! I've tried this:

but all i get is this: (when i view source)

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HEAD>
<META content="text/html; charset=windows-1252" http-equiv=Content-Type></HEAD>
<BODY></BODY>

I've even tried without the "/" behind, without the ",1"
even without "http://", but i keep getting the same results and a blank page. Can someone please help me?
