In preparation for generating method signatures for the manual.
This change gets rid of bogus false|null return types, a few unnecessary trailing backslashes, and settles on using ? when possible for nullable types.
* 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.
crypt() without salt generates a weak $1$ MD5 hash. It has been
throwing a notice since 2013 and we provide a much better alternative
in password_hash() (which can auto-generate salts for strong
password hashes), so keeping this is just a liability.
User-defined functions can't have multiple parameters with the same name.
Don't do that for var_dump/debug_zval_dump.
Consistently use array $array to match docs
Fix typo in UPGRADING
Fixes GH-6015
This is targeting 8.0.
`$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.
It does not make sense to throw a `TypeError` when the stream can't be
analyzed. If `sapi_windows_vt100_support()` is used as getter, we just
return `false` in that case; if the function is used as setter, we
additionally trigger a warning.
We also fix the test cases for this function, which have been broken
before. Note that these tests are still whitespace sensitive.
`SIGTERM` is only defined in ext/pcntl, and as such never available on
Windows. Moving the constant to ext/standard does not make much sense,
because that parameter is actually unused on Windows. Therefore, we
use the magic number `15` instead, what is also done in the PHP manual.
The second argument should be mt_getrandmax(), not PHP_INT_MAX.
Additionally this function only accepts either zero or two arguments,
so err on the side of being conservative and mark both UNKNOWN.
