PHP 8.4 Object Interfaces not supported? #870
Description
Sorry if this has been already addressed.
Seems that Object Interfaces are not supported. The extensions show no errors, you get a fatal error:
interface I
{
// An implementing class MUST have a publicly-readable property,
// but whether or not it's publicly settable is unrestricted.
public string $readable { get; }
// An implementing class MUST have a publicly-writeable property,
// but whether or not it's publicly readable is unrestricted.
public string $writeable { set; }
// An implementing class MUST have a property that is both publicly
// readable and publicly writeable.
public string $both { get; set; }
}
// This class fails in implementing the interface
class C1 implements I
{

Good point @gremo ,
We support object interfaces of course, but we don't check that the interface property is implemented by its class (so there is no warning in problems window).
Will be implemented!

@jakubmisek Yes, of course — I meant that no error is reported. Thanks, and as always, great job and thanks for the speed with which you handle issues!

@gremo thank you, we'll try to add property checks on interfaces in future update!
