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
