@grmpyprogrammer more specifically, I think I meant more like an abstraction layer around FFI, similar to how FrankenPHP/Swoole provides an implementation/framework for Fiber usage

@grmpyprogrammer is NumPHP not what you're looking for?

https://numphp.org/

Is it more about NumPY's API specifically?

@anthony I could be wrong but numpy is backed by some external libraries and would want that approach for “numpy for PHP”

Girgias, 18 days ago

@grmpyprogrammer @anthony The "problem" is that numpy and libraries based on it (like pandas) can't truly work in PHP, as multiplication is assumed to be commutative.

A thing that matrices are famously not.

I really do not have the will power to fight Dmitry on this topic at this point in time (c.f. https://github.com/php/php-src/pull/9218) so if someone wants to drum-up support and possibly write the required RFC, then please do it.

@Girgias @anthony I appreciate the context — I am not sure if I could even write an RFC for this given that I couldn’t do any of the work (no C/C++ skills)

@grmpyprogrammer @anthony The C/C++ is really not hard, it is just modifying one line of code in one specialization: https://github.com/php/php-src/pull/9218/files#diff-773bdb31563a0f907c75068675f6056b25f003e61f46928a31d9837ae107460dL165-R165

One could make it more complete by creating a new specialized multiplication handle for int/float, similar to what addition does. (As + in PHP is not always commutative (because array "addition")).
