Deprecated: Return type of rotate_filter_nw::filter($in, $out, &$consumed, $closing) should either be compatible with php_user_filter::filter($in, $out, &$consumed, bool $closing): int, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /in/lQ88Q on line 5 string(12) "ello, worldd"
