How to create a docker image for php and node?

I am trying to create a docker container for my angular that has php file in it. Angular requires npm so I need to have nodejs installed. I don't need apache for my project, just pure php should work fine.

My understanding is I should have a

FROM node:latest

..install php here

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

COPY package.json /usr/src/app
RUN npm install

COPY . /usr/src/app

I am not sure how to install php in my case, Can anyone point me to the right direction? Thanks a lot!
