Create an xml file using php?

[Arenlor]

I've been working at this for a while, the only thing I can't figure out is how to create the actual XML file, I know how to add all the information I want to have in the XML file and all that, it's the creating the file that I can't seem to do (yes this is for an RSS thing, I need to let idiots fill in forms and update it)

[StupidScript]

function genOutput() {
$output = header("Content-type: text/xml");
$output.= "<container>\n";
$output.= "<title>".$title."</title>\n";
$output.= "<text>".$text."</text>\n";
$output.="</container>\n";
return $output;
}

and so on. Build it like you would an HTML page, and include the proper headers, then send that $output back to the client.

it's basically a text file - you do the same open, while loop, write, close, etc.
