note 81612 added to function.simplexml-import-dom

Something that surprised me, any changes made to the SimpleXML object obtained from the imported DOMDocument also change the original DOMDocument. e.g. <?php $string = '<root><foo>abc</foo></root>'; $domxml = DOMDocument::loadXML($string); $simplexml = simplexml_import_dom($domxml); $simplexml->foo = "xyz"; $simplexml->bar = "123"; echo $domxml->saveXML(); ?> Outputs: --START-- <?xml version="1.0"?> <root><foo>xyz</foo><bar>123</bar></root> ---- Server IP: 64.71.164.2 Probable Submitter: 59.167.146.189 ---- Manual Page -- http://www.php.net/manual/en/function.simplexml-import-dom.php Edit -- https://master.php.net/note/edit/81612 Del: integrated -- https://master.php.net/note/delete/81612/integrated Del: useless -- https://master.php.net/note/delete/81612/useless Del: bad code -- https://master.php.net/note/delete/81612/bad+code Del: spam -- https://master.php.net/note/delete/81612/spam Del: non-english -- https://master.php.net/note/delete/81612/non-english Del: in docs -- https://master.php.net/note/delete/81612/in+docs Del: other reasons-- https://master.php.net/note/delete/81612 Reject -- https://master.php.net/note/reject/81612 Search -- https://master.php.net/manage/user-notes.php
