Interface for reflection entities who implements getAttributes method

Hi Internals, hope you are all well.

I've been playing around with Attributes and found that the only
way for safely type hint for reflection entities who implement the
getAttributes method is the following union:

ReflectionClass|ReflectionClassConstant|ReflectionFunctionAbstract|ReflectionParameter|ReflectionProperty

$reflectionEntity

For a single use case this was ok, but i would like to survey if
people here would be interested in the introduction of a interface
against which we could correctly ensure, with less effort, that
getAttribute is available.

I believe that it would be something along the lines of:

interface AttributeReflector {

public function getAttributes(?string $name = null, int $flags = 0):

array;

}

I have no experience with the PHP's source code, but if you think
that it's a good idea I would like to propose an RFC along with a PoC
patch to make this adition.

Thanks for your time until now and all the good work I've seen here.

I've run into this problem as well. I think all Reflector children support attributes, so it may not need a separate interface. However, the entire Reflection class hierarchy is a mess and needs a number of additional interfaces added to it generally. It makes sense to overhaul it holistically to make sure it all fits together.

I have zero availability until mid-March, but I'm open to helping at that point.

ReflectionZendExtension and ReflectionExtension are currently the only ones
who implement Reflector but don't support attributes.

However, the entire Reflection class hierarchy is a mess and needs a
number of additional interfaces added to it generally. It makes sense to
overhaul it holistically to make sure it all fits together.

Was not aware of other cases, but a quick look led to:

getExecutingFile() : string and getExecutingLine() : int in
ReflectionFiber and ReflectionGenerator;
getDocComment() : string|false in ReflectionClass,
ReflectionClassConstant, ReflectionFunctionAbastract and ReflectionProperty;
getName(), getNameSpaceName() and getModifiers() in some cases (not
always together).

Should it be the case to expand the scope to handle these in the same
proposal or maybe create a Meta RFC and discuss each on their own?

I have zero availability until mid-March, but I'm open to helping at that
point.

Thanks for your return on that, I'll try to run at least a little on my own
foot until there, so I can be less of a burden!

I have been considering a "clean up reflection's class hierarchy" RFC myself; things like getName() are also ubiquitous, but AFAICT is not actually in a common type definition anywhere.

I think a single RFC to clean up all the bits is probably the place to start. If any particular part of it ends up being controversial we can consider splitting it off then.

Shoot me an email off list sometime in March as a reminder and let's see what we can figure out. :-) Or stop by the room 11 chat room.

Sounds good to me. I'll work on something along those lines and

get in touch with you sometime after mid of this month!

There is also ReflectionAttribute itself which does not have getAttributes().

Hello list.
Another potential benefit of such interfaces can be polyfills.

PHP 8.x: class ReflectionClass implements Reflector, AttributesHaving {..}
PHP 7.x. class UserlandReflectionClass extends ReflectionClass
implements AttributesHaving {..}

function f(AttributesHaving $reflector) {
$attributes = $reflector->getAttributes();
...
}

I wonder if it should be called "AttributeReflector" or
"AttributesHaving" or "AbleToHaveAttributesBeing" :)
