I just released there is no PHP example https://www.howtographql.com Also a tip in the Node.js section it would be great if you added a section or additonal chapter detailing on how to deploy either to zeit now or heroku. This things can be tricky considering that graphql is API operating over HTTP

that's a great suggestion Nick! Can you share it here: https://github.com/howtographql/howtographql? 🙂
