Previous Comments: ------------------------------------------------------------------------ [2009-02-20 23:48:09] felipe@php.net The problem is the 'retval = EG(uninitialized_zval_ptr);' in dom_read_property(), I guess that maybe would be more suitable throw an E_RECOVERABLE_ERROR there. Assigned to maintainer. ------------------------------------------------------------------------ [2009-02-18 23:47:36] felipe@php.net I can reproduce it using 5.3CVS. ------------------------------------------------------------------------ [2009-02-18 00:39:01] bisyarin at ukr dot net I've tried PHP 5.2.9RC3-dev on windows and FreeBSD and still the same. Output from my win-machine: version: PHP 5.2.9RC3-dev (cli) (built: Feb 17 2009 23:39:59) Error message: PHP Fatal error: Cannot use object of type stdClass as array in D:\artem\phpDOMBagTest.php on line 19 Output from my FreeBSD machine: version: PHP 5.2.9RC3-dev (cli) (built: Feb 18 2009 02:14:56) Error message: Fatal error: Cannot use object of type stdClass as array in /usr/home/artem/comps/scripts/phpDOMBagTest.php on line 19 ------------------------------------------------------------------------ [2009-02-17 23:54:19] jani@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://windows.php.net/snapshots/ ------------------------------------------------------------------------ [2009-02-17 23:01:30] bisyarin at ukr dot net Description: ------------ In one of my project's libraries I've forgot to check DOMNode's "previousSibling" property for existence by accident. I think that DOM extension should handle such situations gracefully. But after that, when I try to create an array by assigning a value to unexistent key with square bracket syntax, I get an error message: PHP Fatal error: Cannot use object of type stdClass as array in /xxx/yyy.php on line ZZZ Reproduce code: --------------- $xml = '<?xml version="1.0"?><html><p><i>Hello</i></p><p><i>World!</i></p></html>'; $dom = new DOMDocument(); $dom->loadXML($xml); $elements = $dom->getElementsByTagName('i'); foreach ($elements as $i) { $i->previousSibling->nodeValue = ''; } $arr[0] = 'Value'; print_r($arr); Expected result: ---------------- Array ( [0] => Value ) Actual result: -------------- PHP Fatal error: Cannot use object of type stdClass as array in /usr/home/artem/comps/scripts/test.php on line 20 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47430&edit=1
