Hi,

If I'm understanding the definition of stable here, it means that if two values

Hi Nikita,
while we're changing the naming scheme, could we also get rid of the
NUL byte, please? Binary in logs due to things like get_class really
isn't that nice.
Regarding checking whether something is an anonymous class, how about

Note that a comparison callback can also be broken in other ways:
- It could contain a loop, e.g. 'a' < 'b', 'b' < 'c', 'c' < 'a'.
- It could have alternating return values in subsequent calls with the same
arguments.
This kind of misbehavior cannot be easily detected.
The best we can do is make s
Hi Dan,
Thanks for taking the time to bring up your concerns. While I don't expect to
change your mind (nice though that would be!) perhaps other readers here will
find my counter-positions useful.

A new SORT_STABLE flag would be great!

I'd be interested in having a stable sort.
When migrating from php 5.6 to 7 a long time ago,
the fact that sorting was no longer stable was an inconvenience

Probably for more clear wording (since outside of context "PHP" can mean
many things).
Since 3.0 and 3.01 are essentially the same license, I'm no

Hi internals,
Sorting function in PHP currently do not guarantee stability, which means
that the result order of elements that compare equal is not defined.
To achieve a stable sort, you need to do something like this (untested):
$arrayAndPos = [];
$pos = 0;
foreach ($array as $value) {
$arr
