PHP - how to display soap response sub children list - php

Question

I got a response in the following xml format like below:
How can I get list->item->value in one row or container:
<list>
<item>
<Key>3</Key>
<Value>3960</Value>
</item>
<item>
<Key>5</Key>
<Value>3967</Value>
</item>
<item>
<Key>6</Key>
<Value>3968</Value>
</item>
</list>
How can I display the value like this below
<table>
<tr>
<td>3960, 3967, 3968</td>
<td>3963, 3961, 3960</td>
</tr>
</table>
and at the moment I try to use children() in foreach, but it returns error: Call to a member function children() on null, and below is my php code
foreach($items as $item){
echo '<td>';
$child_item = '';
foreach($item->list->children()->children() as $child)
{
$child_item .= $child .' ,';
}
echo rtrim($child_item,' ,');
echo '</td>';
}
Thanks experts!

This is what you need to achieve that:
<?php
$xmlstr = <<<XML
<root>
<list>
<item>
<Key>3</Key>
<Value>3960</Value>
</item>
<item>
<Key>5</Key>
<Value>3967</Value>
</item>
<item>
<Key>6</Key>
<Value>3968</Value>
</item>
</list>
<list>
<item>
<Key>3</Key>
<Value>3963</Value>
</item>
<item>
<Key>5</Key>
<Value>3961</Value>
</item>
<item>
<Key>6</Key>
<Value>3960</Value>
</item>
</list>
</root>
XML;
$items = new SimpleXMLElement($xmlstr);
echo "<table>\r\n";
echo "<tr>\r\n";
foreach($items as $list){
echo "<td>";
$itemsArr = array();
foreach($list as $item){
$itemsArr[] = $item->Value[0];
}
echo implode(", ", $itemsArr);
echo "</td>\r\n";
}
echo "</tr>\r\n";
echo "</table>";
?>
