It depends where you're at with the PHP stuff. If you're using a LAMP stack (as you mention) but using something like MAMP/XAMPP and keeping it simple, staying away from the terminal or PHP frameworks like Laravel, etc then most of this other stuff will be hard for a bit. Ruby on Rails is always talked about as being "easy" but it's really not at first if you're lacking knowledge of things like package managers, command-line tools, deployment that involves application servers and deployment scripts, MVC patterns, etc. I'll say this: if you've been sticking to PHP to avoid all these things I mentioned then you'll do yourself a favor by picking almost anything (I'd say Rails or a Node stack) and getting into it. Once you get the concepts of these stacks you can use that knowledge to jump to other stacks a lot easier as well. Eventually it all feels kind of similar. You'd even be fine to stick to PHP but would be a much better PHP developer after nailing some of those concepts.
