php array format from xml

Question

$objDOM = new SimpleXMLElement(XML_FILE_NAME, null, true); // load SimpleXML
$current = $objDOM->xpath('picture');
function sort_current($t1, $t2) {
 return strcmp($t2['id'], $t1['id']); // to sort high > low
 }
usort($current, 'sort_current');

How come I am getting an output like this:

Array ( [0] => SimpleXMLElement Object ( [0] => 9 ) [1] => SimpleXMLElement Object ( [0] => 8 ) [2] => SimpleXMLElement Object ( [0] => 6 ) [3] => SimpleXMLElement Object ( [0] => 5 ) [4] => SimpleXMLElement Object ( [0] => 4 ) [5] => SimpleXMLElement Object ( [0] => 3 ) [6] => SimpleXMLElement Object ( [0] => 2 ) [7] => SimpleXMLElement Object ( [0] => 15 ) [8] => SimpleXMLElement Object ( [0] => 1 ) [9] => SimpleXMLElement Object ( [0] => 0 ) )

I wanted to get an output such as this:

Array ( [0] => 8 [1] => 6 [2] => 5 [3] => 4 [4] => 3 [5] => 9 [6] => 2 [7] => 15 [8] => 1 [9] => 0 [10] => )

what do I need to change to get a cleaned up array as above without all the SimpleXMLElement gubbins? Cheers, Andy

SimpleXML returns objects not arrays. You have to convert it, like this guy did here. There are a plenty of these on that page.
