RFCs have been reorganized and radically rewritten.
https://wiki.php.net/rfc/object_scope_prng
The implementation is unchanged, but the background has been explained in
more detail and the execution speed has been re-verified with PHP 8.1-dev.
The proposal seems to have been received relatively
Hi internals.
RFC has been updated to 1.3 and implemented.
https://wiki.php.net/rfc/object_scope_prng
The main changes are as follows:
- `RNG\OSRNG` has been renamed to `RNG\OS`. This was too verbose.
- `rng_rand()` has been renamed to `rng_int()` and the arguments `$min`
and `$max` are now

This is a backwards-compatibility leftover in mt_rand() and we should not
carry it over into a new API.
While this is true, the current implementation of MT in PHP relies on
global state, and I believe that having a

Yes. RNG stands for Random Number Generator, which I think is a common
acronym.
Cryptographic pseudo-random number generators are commonly known as a
CSPRNG.

What does rng stand for? Is it short for range or acronym of random number
generator?
RFC and implementation updated.

https://github.com/php/php-src/pull/6568
> MT19937 returns a signed 32bit number as a result of the `next()` method;
the mt_rand() function returns a bit-shifted unsigned 31bit number, so the
results are not identical.
Updated the RFC and fixed the implementation.
Also made some additions to the RFC about when this feature might be useful.

I have made some fixes to the implementation based on review. The current
implementation can be found at the following address (Thanks Tyson:

Hi internals.
I implemented Type II, which was pointed out by Nikita and fixed.
https://github.com/zeriyoshi/php-src/commit/5ff8882a8fbfaf4ffd5cc42fb5853c4a1a00c182
This is much smarter and simpler than Type I, but the implementation is
more complex (partly due to my lack of knowledge).
