I don't really understand why in 2020 there's still this kind of blind hatred against this language. It often comes from horrible bad memories from previous versions or old frameworks.
Objectively, compared to other languages i've been working with it is more than OK. Despite it's lack of "style" it is easy to understand, host, tests, diagnose and it is powerfull for web applications.
I've been working on a SaaS API with Symfony now for 2 years, our metrics are good...
It is a good tool, it builds good softwares
It's essentially sinking in popularity because of bad faith and lack of hype, really sad !
