I have a similar PHP system on my site using sessions:

I have an admin session, where each step(1-5) is a different 
page(script) and as each page is progressed into a new session is 
registered with the users username, the activity currently being edited 
and the team within this activity they are editing.

This same method could be employed by you where the page title is 
registered as a session variable and echoed to the page. If the user 
goes back a page then check to see if the variable is set and if it is 
then unregister or destroy it, thus delivering an accurate method of 
the users progress throughout the site.

if(!empty($yourvar)) {

Hop this is of some use to you!
