Description:

Hi,

If you var_dump a DOMElement, a DOMNodeList, etc. you have an empty object displayed like that :
DOMElement#130 (0) {
}

Best regards,

Note that the use of Reflection doesn't yield the content either.
Some methods are listed but no property is.
Example:
 ReflectionObject::export($oMyDOMObject);

The bug for the reflection part was already reported in bug 48527.

This is strange.
The commit is into PHP5.4 tree, since 5.4.1
https://github.com/php/php-src/commit/d04682766d66da083d9b14400bd9c75dd9b1463b

Are you sure about your PHP version ?

Hi,

I did a second test today with Debian Wheezy updated-upgraded.
It didn't work :

-----------------------------------------------------------------
root@wheezyDEVLaurent:~# php --version
PHP 5.4.4-14+deb7u9 (cli) (built: Apr 18 2014 14:34:31)

root@wheezyDEVLaurent:~# php
<?php
$oDOMElement = new DOMElement('balise');
var_dump($oDOMElement);
?>
class DOMElement#1 (0) {
}
root@wheezyDEVLaurent:~#
-----------------------------------------------------------------

I also tested it on Ubuntu Trusty with PHP 5.5.9 and it worked.
I don't know why it doesn't work in Debian. Maybe the commit did not make it to the stable version of Debian.

Since it seems to work in later versions, feel free to close the bug.
I'll continue to use work-arounds with Wheezy.

Best regards,
   Laurent Lyaudet

This is fixed in recent PHP versions, as is verified by e.g. https://github.com/php/php-src/blob/master/ext/dom/tests/bug69846.phpt
