NodeJS and PHP hosting

A couple of options are DigitalOcean, AWS (Amazon Webservices) and Heroku.

Personally, I'd go with DigitalOcean. IMO it's the best for small projects; user friendly (good for beginners as well as advanced users), neat stability, easy scalability and best of all: insanely affordable. You can run both in one 'droplet' as you have full control over the OS.
