ID: 52640 Updated by: rricha...@php.net Reported by: ken at smallboxcms dot com Summary: Odd Garbage collection Behaviour with Dom Node -Status: Open +Status: Bogus Type: Bug Package: DOM XML related Operating System: Linux PHP Version: 5.3.3 Block user comment: N Private report: N New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php DOM objects are just wrappers to underlying libxml2 structures and unless directly referenced, i.e. $blah->node = $node, the $node object is no longer referenced outside of the function. Appending the node appends the libxml2 node structure to the underlying xml tree, does nothing in respect to the DOM object wrapper. Previous Comments: ------------------------------------------------------------------------ [2010-08-19 00:32:30] ken at smallboxcms dot com Description: ------------ Variables added to dom nodes are later unset. This behaviour does not appear to happen with other types of PHP objects. Test script: --------------- <?php $blah = new stdClass; function humbug() { /* Behaviour changes when uncommented. Think this is a GC bug. global $node; */ global $blah; $doc = new domDocument('1.0', 'utf-8'); $blah->doc = $doc; $node = $doc->createElement('node'); $doc->appendChild($node); $node->foo = true; $obj = new stdClass; $blah->obj = $obj; $obj->child = new stdClass; $obj->child->foo = true; } humbug(); echo "Should be set: ".$blah->doc->firstChild->foo."<BR>\n"; echo "Is Set: ".$blah->obj->child->foo."<BR>\n"; ?> Expected result: ---------------- I would expect that $blah->doc->firstChild->foo would be set after the function call. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52640&edit=1
