I would likely never touch it as there are too many languages to use and what I know is more than enough to do my job, but I am super excited to see languages like PHP that aren't mainstream in my bubble to keep evolving
The standard library has a lot of good stuff for calling API:s, handling JSON, shelling out, string juggling and HTML publishing on a socket. In every typical install you also have common database interfaces. I've done so much problem solving at breathtaking speed in single file PHP scripts and PsySH over the years.
The threading story isn't or wasn't very good so typically I've done logic in PHP and then driven it from something like a Scheme, Picolisp or Elixir when I've needed it.
There was a point were I thought the language and it ecosystem was going down the drain but then they recovered and modern php is 90% what do you want to do and don't worry about the how, it's easy.
I don't use it much anymore, but every time I do all I see are possibilities.
Of course not if you use vm or serverless or whatever like this, but for a basic here is my crude app, that's what you do.
Or if you want to go old school sure, just scp that directory, it still works like it did 30 years ago.
