This would be a fantastic addition, and it would also alleviate an issue in
static analysis land where it's very tricky (in the general case) to verify
exactly what implications successfully completing a given foreach loop has
on the array being iterated over (e.g.

Hi internals,
I've created an RFC for https://wiki.php.net/rfc/any_all_on_iterable
This was proposed 2 days ago in https://externals.io/message/111711 with some
interest
("Proposal: Adding functions any(iterable $input, ?callable $cb = null, int
$use_flags=0) and all(...)")
- The $use_flags

I have a draft RFC (https://wiki.php.net/rfc/foreach_void) and patch
I would highly prefer php optimalization for it. ArrayKeysIterator can
not even used if the input is iterable instead of pure array.

ok, that seems to be working now as well.
Optimizing foreach (array_keys($arr) as $k) is very important, not only
because of memory, but because of speed when not all elements needs to
be iterated, like:
foreach (array_keys($arr) as $k) {
if ($k some condition) {
break;
}
}
please, can someone send a PR for this?
That is great news, but when will social login functionality be back online?

Hi,
https://edit-new.php.net/ is also down, what is the plan here? Is something
going on? Is there some work in progress to create a new platform or
something?
NB: You have SplFixedArray which can cover some use-cases.

I'm looking forward to an answer from someone proficient in this area

Hello,
For the past couple years I've been working with a PHP code base that
at times deals with quite large payloads memory wise. This has made me
pay more attention to some array operations in PHP that are rather
frustrating to deal with in userland PHP, but could perhaps be
optimized more in

and easy thing is very much in PHP's DNA, but I think we can cover a lot
more ground with a more general purpose solution that leaves userspace to
deal with bigger problems.
I totally agree with you.
Atenciosamente,

Yes, because I can optimize it when array_filter() is "positive-only", but
I can't when I need to be

Yes! It means to be "array_reject()" instead of "array_reverse()". And my
syntax is wrong too, actually it

No, you'd have to put it in a closure
The original poster had a typo, I think, and meant array_reject not
array_reverse. He
Just to confirm
array_filter(“!is_int”, $collection)
Would result in a collection of only non-integers??
I do think there’s something to be said for the communication of intent without
syntax.
array_without or array_reject reads easier to me than making sure to watch for
the bang.
