Edit report at https://bugs.php.net/bug.php?id=75202&edit=1 ID: 75202 Updated by: cmb@php.net Reported by: kelunik@php.net Summary: Interfaces shouldn't be able to define a constructor Status: Open Type: Bug Package: Class/Object related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: I think this issue should be discussed in internals, Niklas. Previous Comments: ------------------------------------------------------------------------ [2017-09-13 09:34:40] kelunik@php.net Description: ------------ Interfaces shouldn't be able to enforce a signature for __construct. Parent classes can't enforce that either, for classes there's no compatibility check, but interfaces have them. See https://3v4l.org/mSPL5 vs. https://3v4l.org/RYdFG This is related to #50302 which I believe is a bug, even if it has been closed as not being one. In case it's decided that this is not a bug, this bug can serve as documentation of it not being a bug. Expected result: ---------------- Probably a compile time error, that the interface defines __construct. Actual result: -------------- The interface is defined with __construct and the signature enforced in classes implementing it. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75202&edit=1
