Considering that the same use-case using non-static attribute, and non static classic $this accesses the attributes just all right in all PHP versions Should private static attributes be inherited, or not ? ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77154&edit=1
