Deprecated: Return type of MyDOMDocument::saveHTML($node = null, $flags = 0) should either be compatible with DOMDocument::saveHTML(?DOMNode $node = null): string|false, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /in/oWkrU on line 7 <div> <div>hello</div> <div>world</div> </div>
