How to print upper folder PHP

Hello can anyone tell me how to print upper folder in PHP from the file which is located in sub folder..

eg: public_html / mysite / music / new / index.php


$home = 'http://mysite.com/';
$current_folder = basename(dirname(__FILE__));
echo '<a href="'.$home.'">Home</a> / <a href="'.$home.$current_folder.'">'.$current_folder.'</a><br/>';


In this code I can link to currennt folder 'new' but how do I link 'music' folder in this script..

Pls Help... :( Tnx n advance :)

Like
echo '<a href="'.$home.'">Home</a> / <a href="'.$home.$current_folder.'">'.$current_folder.'</a><br/>'; since the php variable won't get parsed, when used inside single quotes.
