Could someone comment on best practices for adding breadcrumb to a LAMP site, specifically:

is it better to do it with a function or a class?
with PHP 4.4.1, is javascript even necessary to add breadcrumbs to a site?
Is it necessary to write directory tree (folders and file structure) to a mysql table to improve depth and functionality?

Zend has 2 breadcrumb navigation scripts listed below:
newer: 0 A Cool Recursive Links Script- path.php http://www.zend.com/codex.php?id=362&single=1 is a 4 star
older: Breadcrumbs navigation http://www.zend.com/codex.php?id=414&single=1 is a 0 star

Any comments on these or suggestions to any best practices breadcrumb script?


cheers, deano
