What I like about PHP is that it's not just batteries-included, it's "Entire Batteries Plus Store Included". The standard library is huge, documented, and also features 15 years of accumulated notes and discussion right on php.net.
The tendency to have a npm package for everything is overwhelming because you end up with choice paralysis and risk on picking "Oh, you picked CSV-to-array library #823, it's the buggy/insecure/unmaintained one."
File reading excluded, CSV to array is like two generator functions and a main, even with rudimentary schema support. No reason to add a dependency at all.
