#47430 [NEW]: Errors after writing to nodeValue parameter of an absent previousSibling

From: bisyarin at ukr dot net Operating system: FreeBSD, Windows XP PHP version: 5.2CVS-2009-02-17 (snap) PHP Bug Type: DOM XML related Bug description: Errors after writing to nodeValue parameter of an absent previousSibling 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 bug report at http://bugs.php.net/?id=47430&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47430&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47430&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47430&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47430&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47430&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47430&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47430&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47430&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47430&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47430&r=support Expected behavior: http://bugs.php.net/fix.php?id=47430&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47430&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47430&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47430&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47430&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47430&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47430&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47430&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47430&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47430&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47430&r=mysqlcfg
