This kind of toxic mentality doesn't produce better code, and it sure doesn't produce better coders. It's just free-floating hostility and gatekeeping.
Here's a few parts of PHP that improved in the past 6 years:
* Static type declarations (and return types, and strict typing, ...)
* Composer has become the de facto package manager for the PHP ecosystem
* Better cryptography (bye mcrypt, hello sodium)
* High quality open source libraries (i.e. Guzzle)
And I haven't even reviewed all of the changes coming in 8.0.
