One reason why C > PHP. It has much better tooling. I tried to use PHP with emacs. There is no good working lsp server, so you are stuck with ctags or even worse completion by html doc file (that's how php emacs mode can work lol). I wish to switch my money grind stack just because of lack of tooling. I find that even Java has better support in gnu emacs, it is especially hard to edit Symfony code in Emacs, because it differs from "vanilla" php project too much.
