ID: 25264 Updated by: schst@php.net Reported By: marshall at exclupen dot com -Status: Assigned +Status: Closed Bug Type: PEAR related PHP Version: Irrelevant Assigned To: schst New Comment: This bug has been fixed in CVS. In case this was a PHP problem, snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/. In case this was a PHP.net website problem, the change will show up on the PHP.net site and on the mirror sites in short time. Thank you for the report, and for helping us make PHP better. This has been added for the current CVS version. There are sveral ways of reading XML with attributes, as well as writing attributes. Will be included in the next release.

Here's a hypothetical example using http://pear.php.net/rss.php as a base: Array ( [channel] => Array ( [language] => en [image] => Array ( [url] => http://pear.php.net/gifs/pearsmall.gif [link] => http://pear.php.net/ ) ... } Now, I know this would be against the RSS spec (I just needed an example XML file), but what if "image" had width and height attributes? [image] => Array ( [url] => http://pear.php.net/gifs/pearsmall.gif [link] => http://pear.php.net/ [attr_width] => 104 [attr_height] => 50 ) All is well and good there. Now imagine that "link" has a "title" attribute: [image] => Array ( [url] => http://pear.php.net/gifs/pearsmall.gif [link] => Array { [0] => http://pear.php.net/ [attr_title] => PEAR } } Suddenly, "link" has changed from a string to an array. If the attributes are optional, you could never be sure which it would be. The 0 is used as a key to avoid naming conflicts that could come up with "content" or "data". One solution would be to make every value an array. Strings would become arrays with only 1 element (key 0). Reproduce code: --------------- require_once 'XML/Unserializer.php'; $options = array('complexType' => 'array'); $unserializer = &new XML_Unserializer($options); $unserializer->unserialize('http://pear.php.net/rss.php', true); $rss = $unserializer->getUnserializedData(); echo "<pre>"; print_r($rss); echo "</pre>"; ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25264&edit=1
