I'm not sure if React and Symfony (a PHP web framework) is a good combination. With the modern JS frameworks (React, Angular etc.) server based web frameworks seems to be dead, at least for new projects. If I were you I'd choose another language for the business layer (Python, Kotlin etc.) instead of PHP.
You are entitled to your own preferences of course, but the idea that the client/server model is dead is simply not true... Traditional frameworks have become very good at serving APIs.
cough cough GraphQL cough cougghhh
What about it?
I didn't say that. I said web frameworks in general, language agnostic. If all the view/controller processig is moved to the browser and the server simply serves REST services many functionalities of the framework are not used. I'm thinking about Struts, JSF, Spring MVC. I don't know the PHP world, maybe its frameworks do different things but I doubt it.
