Issue: https://github.com/php/php-src/issues/11290 Author: fluffycondor ### Description This is a longstanding one (sorry for the php-dom day!). Sometimes the same code from #11288 causes crash on every 8.x PHP version. The code is the same, but the html markup is slightly differs. Live reproducing: https://3v4l.org/KjJgQ // On every PHP 8.x version throws DOMException: Not Found Error, hangs for 1-15 seconds, then crashes. https://3v4l.org/FdOZR // Hangs for 1-15 seconds, crashes on every PHP versions but PHP 8.2.6 and 8.1.19. It's kinda related to #11289 and #11288, but this is a longstanding one. I guess this is a part of a big picture, so I hope this would help to investigate the main cause of weird php-dom behavior. The following code: ```php <?php $html = <<<HTML <!DOCTYPE HTML> <html> <body> <p><span class="unwrap_me">Lorem</span><span class="unwrap_me">ipsum</span><span class="unwrap_me">dolor</span></p> </body> </html> HTML; $dom = new DOMDocument(); $dom->loadHTML($html); $spans = iterator_to_array($dom->getElementsByTagName('span')->getIterator()); foreach ($spans as $span) { if ('unwrap_me' === $span->getAttribute('class')) { $span->replaceWith(...$span->childNodes); } } ``` results in crash on every PHP 8.x version. ### PHP Version PHP 8.x ### Operating System _No response_
