Hi Internals, I have limited the RFC to disabling autovivification on false only, which was the initial scope of the RFC. The only two possible cases remaining will be undefined and null. After what Tyson Andre clearly explained, null is commonly used and leads to many more complex situations.
I have opened voting on https://wiki.php.net/rfc/autovivification_false which will end on 2021-06-23T20:00:00Z Link to the discussion thread: https://externals.io/message/114595 The implementation is pending, but if someone wants to suggest one, please feel free. Regards, Kamil
