I have this code currently (I'm not a hardcore coder):

Code:
<?php
// Rename Directory to name
$dir = basename(dirname(__FILE__));
echo ucwords(str_replace('-', ' ', $dir));
?>
Currently it echos the directory a file is in while stripping out dashes in the file directory name. Works great for me.

What I am trying to do is use PHP code to create a back link so when the link is clicked, the user will go to the next directory up in the hierarchy.

For example: I'm in Home > automotive > motorcycle-and-atv > protective-gear so I'm in the protective gear section of the site.

I want to make a link that says something like:

Back to {Directory one level up}

In this case it would be:

Back to Motorcyle And ATV

When clicked, it goes to the directory one level up (which I have an index.php page in every directory so it would technically go to the index.php page).

Any help would be very much appreciated.
