I think PHP is up and coming. I think PHP is really good, and frameworks like Laravel make it really good. I reckon it will hold in the future. It's a tough choice if you need to choose one or the other to learn. I think PHP is easdier to learn because its so established and there's so many resources for it... however javascript and Node.js, from what I've seen, appear to be more valuable to employers as compared to PHP. For that reason, I'd go with node.js if I was starting out AND looking to move into that role for a career. Personally, I'll be writing my next thing in PHP
