Using react.js with php and php frameworks

Question

Hi

I've worked with php and now looking at using a framework like codeignitor. I also want to have an interactive front-end so I'm considering react.js which is the View of the MVC.

 

As I'm using the View aspect through React can I still use frameworks such as codeignitor which already has a view as its based on MVC?

Is there much point using codeignitor if I'm going to be using React?

 

Thanks
