Surely you could try it out yourself to discover what it does? :)
You could also read the documentation:
http://book.cakephp.org/view/1438/meta
Putting this command:
echo $this->Html->meta('icon');
into a view will cause CakePHP to output these tags:
<link href="/favicon.ico" type="image/x-icon" rel="icon" />
<link href="/favicon.ico" type="image/x-icon" rel="shortcut icon" />
The purpose of these tags is to inform the web browser where the page's favicon
("favorite icon") is, which the browser might display to the left of the URL in
the address bar, in the window title, in the tab title, and/or in the bookmarks
(or "favorites") menu. Browsers that support favicons know that the default
icon file is /favicon.ico so unless you want to change the icon's location,
these tags are probably unnecessary, but perhaps useful in that they provide an
indication that the document does have a favicon.

First, note that echo is a language construct, not a function, hence it is not
proper to use parentheses. That is, use "echo $str" not "echo($str)". See:
http://php.net/echo
Second, your function output() appears to be nothing more than a wrapper around
echo, in which case, why not just use echo in the first place?
What is the problem you're trying to solve here -- why do you believe the many
opening and closing php tags and the many echo calls are a problem?
Finally, "doesn't seem to work" doesn't provide us with any information that
would enable us to help you. (Explain *how* it doesn't work: what did you
expect to happen, and what did it do instead.)
