Felipe Pena 42feeddd40 MFH: 
- 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)
