* Support the `#[\AllowDynamicProperties]` attribute in stubs
* Use `#[\AllowDynamicProperties]` attribute in stubs
* Disallow applying both `@strict-properties` and `#[\AllowDynamicProperties]`
https://wiki.php.net/rfc/strtolower-ascii means that these functions no longer
depend on the current locale in php 8.2. Before that, this was unsafe to
evaluate at compile time.
Followup to GH-7506
Add strcmp/strcasecmp/strtolower/strtoupper functions
Add bin2hex/hex2bin and related functions
Update test of garbage collection using strtolower to use something else to create a refcounted string
Behavior is same as for (int) $resource, just under a clearer
name. Also type-safe, in that the parameter actually needs to
be a resource.
Closes GH-5427.
Currently, disabling a function only replaces the internal
function handler with one that throws a warning, and a few
places in the engine special-case such functions, such as
function_exists. This leaves us with a Schrödinger's function,
which both does not exist (function_exists returns false) and
does exist (you cannot define a function with the same name).
In particular, this prevents the implementation of robust
polyfills, as reported in https://bugs.php.net/bug.php?id=79382:
if (!function_exists('getallheaders')) {
function getallheaders(...) { ... }
}
If getallheaders() is a disabled function, this code will break.
This patch changes disable_functions to remove the functions from
the function table completely. For all intents and purposes, it
will look like the function does not exist.
This also renders two bits of PHP functionality obsolete and thus
deprecated:
* ReflectionFunction::isDisabled(), as it will no longer be
possible to construct the ReflectionFunction of a disabled
function in the first place.
* get_defined_functions() with $exclude_disabled=false, as
get_defined_functions() now never returns disabled functions.
Fixed bug #79382.
Closes GH-5473.
* get_parent_class() argument is optional
* Mark array_filter() $callback as optional
* The $base of gmp_strval() is optional
* DateTime constructor also accepts zero arguments
* hash_update_file() stream context is optional
* xmlwriter_write_dtd_entity() $isparam argument is optional
Signature stubs for internal functions are specified in xyz.stub.php,
from which we generate actual arginfo structures in xyz_arginfo.h.
This file then needs to be included in the implementation appropriately.
Arginfo from stubs can be regenerated using scripts/dev/gen_stub.php.
However, this should also automatically happen when the stub file is
modified.
