In terms of practical effect, frameworks influence developers more than languages do.
OTOH if someone says they use "Python" for webdev I assume Flask/Django/etc.
But PHP developers always did seem to have inappropriate jealousy over unrelated languages like Java where there is persistence over requests.
Though maybe some of them have found simplicity again.
Tainted strings should be built into PHP (there was an RFC for it but it didn't pass). Another solution could be using operator overloading instead (that RFC didn't pass either).
I'd hope new stuff is also CGI-based and restart on every request, otherwise you're asking for security issues (like leaking another user's info Heartbleed-style).
I wonder if OOP as a technique will eventually always end up as Rube Goldberg machine.
Aren't "big ball of mud"s legendary for being counter-intuitively successful products?
It is always the programmers that is the limitation, not the chosen technology. Thus you should pick technology that makes sense for the majority of programmers. PHP fits that. Just follow a guide to avoid BBOM.
I've seen microservices that had absolutely no guardrais going off the hill too many times. At my previous job "migrations" where bash scripts with SQL in them because they "didn't like ORMs and they were slow". LOL. They were handling signup form POSTs and profile updates.
