Thanks that helps a lot. PHP is pretty good language to start with. I do agree it is worth adding to your toolbox. I personally have moved to it because it is where the future of the web (i believe) is going. Real time, web socket, internet of things (devices) all integrate with the node use case well. PHP is good for web dev, but node is transitioning to allow one to go far beyond web development. I believe that if you want to be a developer, your skill set and pay rate coming out of school will be much higher if you have significant node experience rather than significant PHP experience.
