This allows writing
array_merge(...$arrays)
instead of
array_merge([], ...$arrays)
and is in line with similar changes to array_push() and array_unshift()
in PHP 7.3.
Closes GH-4175.
- Removed the undocumented object support in the leftover array functions [DOC]
(natcasesort, natsort, array_walk, array_walk_recursive, array_unique, array_key_exists)
- Changed HASH_OF() to Z_ARRVAL_P()
- Fixed bug #45937 (array_walk and array_walk_recursive can alter private/protected object variable)
