Bug introduced by
It seems like $db_settings can also be of type false; however, parameter $args of wp_parse_args() does only seem to accept array|object|string, maybe add an additional type check? ( Ignorable by Annotation )

If this is a false-positive, you can also ignore this issue in your code via the ignore-type  annotation
