Implement printing for ReflectionAttribute. Attributes aren't
printed as part of reflection output for other structures (classes
etc) yet.
Closes GH-6117.
While the typed property ensures that the value is a string,
we should make sure that we handle an unset property gracefully.
Do this by throwing the same error we would normally throw if
you access an uninitializde typed property.
ReflectionReference::fromArrayElement(array $array, int|string $key): ?ReflectionReference
is going to be its official signature for PHP 8.0.
Closes GH-5651
This solves [#79628](https://bugs.php.net/79628).
Similar to `ReflectionClass::getMethods()` and `ReflectionClass::getProperties()`,
this new `$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.
This deprecates:
ReflectionParameter::isArray()
ReflectionParameter::isCallable()
ReflectionParameter::getClass()
These APIs have been superseded by ReflectionParameter::getType()
since PHP 7.0. Types introduced since that time are not available
through the old APIs, and their behavior is getting increasingly
confusing. This is how they interact with PHP 8 union types:
* isArray() will return true if the type is array or ?array,
but not any other union type
* Same for isCallable().
* getClass() will return a class for T|int etc, as long as the
union only contains a single type. T1|T2 will return null.
This behavior is not particularly reasonable or useful, and will
get more confusing as new type system extensions are added.
Closes GH-5209.
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.
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.
Make sure we still perform a zpp check for the static case, and
also always enforce that the parameter is ?object. Otherwise we
violate the specified signature.
