From: Operating system: Linux PHP version: 5.3.2 Package: DOM XML related Bug Type: Bug Bug description:Extending DOM classes work only if copy of object present
Description: ------------ Extending some DOM classes (f.e. DOMDOcument, DOMElement I think others, but not tested) work. But when such elemenmt appended to the document, additional information lost. Meantime, when copy of object saved alsewere, all work as expected. First mention of this bug and initial workaround in comment http://php.net/manual/tr/book.dom.php#80613 by ryoroxdahouse at hotmail dot com. I make automattical workaround like ( http://hinikato.blogspot.com/2009/10/domelement.html? showComment=1270202266600#c284093039037001302 ): class MyElement extends DOMElement { public function __construct($name, $value = null, $uri = null) { parent::__construct($name, $value, $uri); $GLOBALS['PHP_HACK_DOM_ELEMENT'][spl_object_hash($this)] = $this; //Note, reference is not enough :( } public function __destruct() { unset($GLOBALS['PHP_HACK_DOM_ELEMENT'][spl_object_hash($this)]); } } But as we need object copy, not just reference it requires double of memmory! Test script: --------------- <? class MyElement extends DOMElement{} $doc = new DOMDocument(); $doc->appendChild(new MyElement('test')); var_dump($doc->documentElement); ?> Expected result: ---------------- object(MyElement)#4 (0) { } Actual result: -------------- object(DOMElement)#4 (0) { } -- Edit bug report at http://bugs.php.net/bug.php?id=51462&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=51462&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=51462&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=51462&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=51462&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=51462&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=51462&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=51462&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=51462&r=needscript Try newer version: http://bugs.php.net/fix.php?id=51462&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=51462&r=support Expected behavior: http://bugs.php.net/fix.php?id=51462&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=51462&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=51462&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=51462&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=51462&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=51462&r=dst IIS Stability: http://bugs.php.net/fix.php?id=51462&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=51462&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=51462&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=51462&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=51462&r=mysqlcfg
