Edit report at https://bugs.php.net/bug.php?id=78677&edit=1 ID: 78677 Updated by: sjon@php.net Reported by: pavel at bunaev dot ru Summary: Parameter Type Widening not properly documented -Status: Closed +Status: Verified Type: Documentation Problem Package: Class/Object related Operating System: 18.04.1-Ubuntu PHP Version: 7.2.23 Block user comment: N Private report: N New Comment: reopening as a documentation bug Previous Comments: ------------------------------------------------------------------------ [2019-10-17 10:53:51] pavel at bunaev dot ru Indeed, this is not a bug. Somehow I missed this point in the documentation :( I apologize for wasting your time in vain Thanks for the clarification. ------------------------------------------------------------------------ [2019-10-17 09:12:32] cmb@php.net Well, there is a note in the Interfaces section[1], but this is only correct for PHP 7.2 and up (and even too general for 7.2), and it doesn't cater to inheritance in general. It seems to me that this should be documented in the Inheritance section[2]; we could link to that section from other parts of the manual where appropriate.
