Test case "ext/standard/tests/array/range.phpt" failed on ARM64 machine
only under RELEASE mode.
How to reproduce it:
```
./buildconf -f; ./configure; make -j 128
make test TESTS="-d opcache.enable=1 -d opcache.enable_cli=1 ext/standard/tests/array/range.phpt"
```
Root cause:
I suspect the root cause is that on ARM64 machine, PHP RELEASE mode
produces different values for internal function range() compared to
DEBUG mode.
Take the downsized test case downsize-range.php [1] as an example. We
applied the check-element.diff patch to check the original values. Note
that we print out the floating point numbers with precision 16.
From the outputs in file output.md, we can see the 7-th and 9-th
elements are different between RELEASE and DEBUG.
To be honest, I didn't get where such difference comes from and probably
this is due to different compilation options used by RELEASED and DEBUG.
Fix:
After commit [2], serialize_precision is used for var_dump(). As a
result, the pre-set "precision=14" didn't work actually.
In this patch, we turn to set serialize_precision as 14 and therefore
the difference between RELEASE and DEBUG can be eliminated.
Note-1: this failue didn't occur on x86 machine.
Note-2: in my local test, this is the only test case which behaves
differently on ARM64 machine under RELEASE and DEBUG mode.

Updates the deprecation message for implicit incompatible float to int conversion from:
```
Implicit conversion from non-compatible float %.*H to int in %s on line %d
```
to
```
Implicit conversion from float %.*H to int loses precision in %s on line %d
```

This format matches against null bytes, and prevents the test
expectation from being interpreted as binary data.
bless_tests.php will automatically replace \0 with %0 as well.
compact() is documented (https://www.php.net/manual/en/function.compact) as a variadic function accepting parameters which are strings or arrays of strings referencing defined symbols.
In actuality, passing nonsense parameters e.g. compact(true, 42) merely returns an empty array. I propose throwing a warning in these cases, to prevent silent bugs.
This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.
This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)

debug_zval_dump() currently prints refcount 1 for interned strings
and arrays, which does not really reflect the truth. These values
are not refcounted, so the refcount is misleading. Instead print
an "interned" tag.

This restricts allowed usage of $GLOBALS, with the effect that
plain PHP arrays can no longer contain INDIRECT elements.

* The array "subject" of a function gets called $array.
* Further parameters should be self-descriptive if used
as a named parameter, and a full word, not an abbreviation.
* If there is a "bunch more arrays" variadic, it gets
called $arrays (because that's what was already there).
* A few functions have a variadic "a bunch more arrays,
and then a callable", and were already called $rest.
I left those as is and died a little inside.
* Any callable provided to an array function that acts
on the array is called $callback. (Nearly all were already,
I just fixed the one or two outliers.)
* array_multisort() is beyond help so I ran screaming.
The second and third arguments are not always the sort_order and
sort_flags -- they can also be in reverse order, or be arrays
altogether. Move them into the variadic parameter to avoid awkward
error messages.
Both of these functions are well-defined when used with a single
array argument -- rejecting this case was an artificial limitation.
This is not useful when called with explicit arguments, but removes
edge-cases when used with argument unpacking:
// OK even if $excludes is empty.
array_diff($array, ...$excludes);
// OK even if $arrays contains a single array only.
array_intersect(...$arrays);
This matches the behavior of functions like array_merge() and
array_push(), which also allow calls with no array or a single
array respectively.
Closes GH-6097.
When using zpp 'f' or Z_PARAM_FUNC, if the fcc points to a call
trampoline release it immediately and force zend_call_function
to refetch it. This may require additional callability checks
if __call is used, but avoids the need to carefully free fcc
values in all internal functions -- in some cases this is not
simple, as a type error might be triggered by a later argument
in the same zpp call.
This fixes oss-fuzz #25390.
Closes GH-6073.
This is targeting 8.0.
`$arg` seems like a poor choice of a name,
especially if the function were to have arguments added.
In many cases, the php.net documentation already has $array for these functions.
E.g. https://www.php.net/manual/en/function.array-intersect.php
I'd assume that since named arguments was added to 8.0 near the feature freeze,
PHP's maintainers had planned to make the names consistent
and gradually use the same name for docs and implementation.
Don't expose references in debug_backtrace() or exception traces.
This is regardless of whether the argument is by-reference or not.
As a side-effect of this change, exception traces may now acquire
the interior value of a reference, which may be unexpected for
some internal functions. This is what necessitated the change in
the spl_array sort implementation.
The only case here that might be *somewhat* sensible is the userdata
argument of array_walk(), which could be used to keep persistent state
between callback invokations -- with the WTF moment that the final
result after the walk finishes will be unchanged. Nowdays, this is
much better achieved using a closure with a use-by-reference.
Make user-exposed sorts stable, by storing the position of elements
in the original array, and using those positions as a fallback
comparison criterion. The base sort is still hybrid q/insert.
The use of true/false comparison functions is deprecated (but still
supported) and should be replaced by -1/0/1 comparison functions,
driven by the <=> operator.
