Need change to the path for this php code. Please help

i have this php code:

<a href='<?php
$ex=explode("/", $_SERVER['SCRIPT_NAME']);
$fn=$ex[count($ex)-1];


$path=str_replace($fn,"",$_SERVER['SCRIPT_NAME']);
$path=substr($path, 1);
echo $site.$path; ?>'><img src='<?php echo $site.$path; ?>images/logo.gif' ></a>

now, i want the path to be going to: http://babyphotobattle.com/aboutus.php istead of going to the index file.

obviously, i dont know how to work on php so any help will be highly appreciated. thanks.

What page is this code running from?

Please show where $site is initialised. Also, please echo the variables $ex, $fn, $site and $path and post the results here.
