''" is not, no matter if $arr or $arr[0] is undefined ------------------------------------------------------------------------ [2019-12-07 19:16:39] contact at kevin-anidjar dot com @requinix@php.net: in previous PHP versions, this code did not throw an error and the returned value was instead considered as null. ------------------------------------------------------------------------ [2019-12-07 19:07:58] requinix@php.net @kevin-anidjar: That does not reproduce the issue. The code must use ?? immediately after a value and without that value going through a function. ------------------------------------------------------------------------ [2019-12-07 19:07:35] bugreports3 at gmail dot com sadly "echo strval($arr['foo']) ?? 'bar';" is a invalid reproducer and expected to thow a warning becaus ein that line strval() is feeded with $arr['foo'] and "?? 'bar'" would only be relevant wehn that returns NULL which is not possible by the nature of strval() this is a completly different beast $oldcontent = $arr[0] ?? ''; ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
