Req #79411 [Opn->Sus]: Support `break` for array_walk/array_walk_recursive

Edit report at https://bugs.php.net/bug.php?id=79411&edit=1 ID: 79411 Updated by: cmb@php.net Reported by: 6562680 at gmail dot com Summary: Support break for array_walk/array_walk_recursive -Status: Open +Status: Suspended Type: Feature/Change Request Package: Scripting Engine problem Operating System: Win10 PHP Version: 7.3.16 Block user comment: N Private report: N New Comment: I think it might make sense to cater to the return value of the callable, but that certainly needs some discussion regarding the details and whether this should really be done, given that there are alternative solutions available right now. However, this bug tracker is not suitable for these kind of discussions, so if you, or anybody else for that matter, is interested in this, please start the discussion on the internals mailing list[1]. Thanks.
