I wonder what a best way to make a breadcrumb with Code Igniter.
1 : Retrieve the strings with URL
example : $this->uri->segment(2)
Using URL segments is specific to how you have your URL structured - there is not always a 1:1 match.

If you want 100% Match and easy to customize use this one :

Breadcrumbs is an small library that helps your manage HTML breadcrumbs with CodeIgniter.
There are some problems with buti's Codeigniter-breadcrumbs library, particularly with the "unshift" method and how it uses Codeigniter's "site_url" method instead of giving you the option to push to breadcrumbs using "base_url". You can check out my fork, since buti's repo is no longer being maintained (since 2012): https://github.com/aburd/Codeigniter-breadcrumbs
