Your application in code igniter is a PHP-Site.You can use Code Igniter to create multiple application using one core. You can create subdomain for each application (not only one domain).

But still in one model for one application. so the application has their own model. and the model can’t be used by other application. :p

Imagine if you has multiple application with the same feature and same database and the application is connected(integrated). so you create a model using copy paste? maybe it can be a problem if you forgot to copy paste.

How to use multiple application using one core and one model? so the application you has created just using one model. and you just create and edit one file. interesting.
