Interesting but how to make this hierarchy ? this i do not know in PHP :-( where can i find code examples ?

This depends too much on how your site is structured for me to give a useful answer. As I said in my reply "If your site can't figure out where it is in the heirarchy then you've got other problems more important than not being able to give the user breadcrumbs." If you actually mean how do you build the HTML I suggest you find a begineers guide to PHP and work through that before tackling breadcrumbs. It's annoying. Why?
