PHP and out of fashion :D. I can't remember when it was in fashion. I wouldn't really say it that way and I am still programming a lot in PHP.
Here's the thing every language has it's ups and downs. Versatility wise I would pick Python since it has the broadest range of all scripting languages. The ducktyping is also a nice addition.
It still cannot hold a candle to Node in pure IO throughput (most languages besides go can't). But it comes with bad naming convention like 'index.js' which even the creator of node says himself.
Both languages cannot hold a candle PHP in documentation and existing infrastructure. PHP is one of the default backend languages over decades now, it's so easy to get any hosting service with PHP running worldwide.
I also actually like a lot of the language choices PHP made and I dislike even more :D ... but in the end I can say this about most languages.
These days I would take rust over all other languages and even there I don't agree with all design decisions.
Also I am missing perl ;D ... where is good old perl ;D .... or Lisp!
so like Maneesh Kumar said .... pick one and start :), every language has it's flaws and I wont even go into cohesion, coherence and other more mathematical topics where almost all scripting languages suck :).
