Web project : Back and Front

I have to build a web project as a medium size project. I need that the app will be responsive( Desktop\ mobile and etc.) The processes will include chat, appointment system, monitoring system, reporting about conditions and etc. I need a basic logic on the server side as a basic BI system.

I would like to receive recommendations about the languages. For the front, I think about: HTML5+Angular Backend: NODEJS or PHP

Any reccomandations?
