Answer 1

try like this.

   $xml = new SimpleXMLElement('<note/>');
   $row = array_flip($row);
   array_walk_recursive($row, array ($xml, 'addChild'));
   echo htmlentities($xml->asXML());

Answer 2

Generate XML with DOM:

$row = array (
  'name' => 'david',
  'bio' => 'good man'
);

$dom = new DOMDocument();
$dom->formatOutput = TRUE;

$note = $dom->appendChild($dom->createElement('note'));
foreach ($row as $name => $value) {
  $note
    ->appendChild($dom->createElement($name))
    ->appendChild($dom->createTextNode($value));
}

echo $dom->saveXml(); 

Output:

<?xml version="1.0"?>
<note>
  <name>david</name>
  <bio>good man</bio>
</note>
