"Fix" in the sense of "not crash". We aren't able to actually
display the default value for this case, as there's no way to
fetch the relevant information right now.
From an engine perspective, named parameters mainly add three
concepts:
* The SEND_* opcodes now accept a CONST op2, which is the
argument name. For now, it is looked up by linear scan and
runtime cached.
* This may leave UNDEF arguments on the stack. To avoid having
to deal with them in other places, a CHECK_UNDEF_ARGS opcode
is used to either replace them with defaults, or error.
* For variadic functions, EX(extra_named_params) are collected
and need to be freed based on ZEND_CALL_HAS_EXTRA_NAMED_PARAMS.

Similar to what is done for ReflectionType itself, copy the
type name stored inside ReflectionProperty. Also make sure the
type field is always initialized for dynamic properties.
This is a non-issue in PHP 8, because we store a pointer to the
property_info there, rather than a copy.
`ReflectionClass` allows reading of the values of private and protected
constants, and also to get private and protected static methods.
Therefore getting the values of private and protected static properties
is also permissible, especially since `::getStaticProperties()` already
allows to do so.
We also allow ::setStaticPropertyValue() to modify private and
protected properties, because otherwise this method is useless, as
modifying public properties can be done directly.
This adds the following APIs:
void zend_call_known_function(
zend_function *fn, zend_object *object, zend_class_entry *called_scope,
zval *retval_ptr, int param_count, zval *params);
void zend_call_known_instance_method(
zend_function *fn, zend_object *object, zval *retval_ptr, int param_count, zval *params);
void zend_call_known_instance_method_with_0_params(
zend_function *fn, zend_object *object, zval *retval_ptr);
void zend_call_known_instance_method_with_1_params(
zend_function *fn, zend_object *object, zval *retval_ptr, zval *param);
void zend_call_known_instance_method_with_2_params(
zend_function *fn, zend_object *object, zval *retval_ptr, zval *param1, zval *param2);
These are used to perform a call if you already have the
zend_function you want to call. zend_call_known_function()
is the base API, the rest are just really thin wrappers around
it for the common case of instance method calls.
Closes GH-5692.
This solves [#79628](https://bugs.php.net/79628).
Similar to `ReflectionClass::getMethods()` and `ReflectionClass::getProperties()`,
this new `$filter` argument allows the filtering of constants defined in a class by
their visibility.
For that, we create three new constants for `ReflectionClassConstant`:
* `IS_PUBLIC`
* `IS_PROTECTED`
* `IS_PRIVATE`
Closes GH-5649.
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.
This is only used in reflection, where doing a simple string check
is acceptable.
I'm also dropping the "dtor" printing in the reflection dump.
Dtors are just one of many magic methods, I don't think there's
a point in explicitly highlighting them, when the name is already
unambiguous.
Closes GH-5353. From now on, PHP will have reflection information
about default values of parameters of internal functions.

Instead fetch the name from the respective structure. The only
place where this is still used is ReflectionClassConst,
as zend_class_const does not store the name.
Instead fetch the name from the function/class/property,
as appropriate. This makes us independent of the property,
and eliminates error conditions related to it.
Directly fetch the name property, instead of construction the
properties hash table and performing a lookup in it. This is both
slow and wastes a lot of memory.
