CodeIgniter on exisiting site

[eluser]esra[/eluser]
If your existing site does not use authentication (user accounts) and sessions, the simple answer is to provide links in the navigation system of the existing site to the CodeIgniter application and links on the navigation system of the CodeIgniter application to the existing site. This is usually done via a menu system. If the existing site uses authentication and sessions, you either need to adapt the existing site to use CodeIgniter code for handling authentication and sessions or vice versa.

However, you would be better off converting the existing site to CodeIgniter\'s MVC architecture if nothing else as a learning experience.
