$doc = new DOMDocument();
$root=$doc->createElement("order");
$doc->appendChild($root);
$textareaNode = $doc->createElement("name");
$textNode = $doc->createTextNode($name);
$textareaNode->appendChild($textNode);
$doc->appendChild($textareaNode);
$textareaNode = $doc->createElement("age");
$textNode = $doc->createTextNode($age);
$textareaNode->appendChild($textNode);
$doc->appendChild($textareaNode);
//header('Content-Type: text/xml');
echo $doc->save($url);

 $doc = new DOMDocument();
 $root=$doc->createElement("order");
 $doc->appendChild($root);
 
 $textareaNode = $doc->createElement("name");
 $textNode = $doc->createTextNode($name);
 $textareaNode->appendChild($textNode);
 $root->appendChild($textareaNode); // use $root, not $doc
 
 $textareaNode = $doc->createElement("age");
 $textNode = $doc->createTextNode($age);
 $textareaNode->appendChild($textNode);
 $root->appendChild($textareaNode); // use $root, not $doc

 echo $doc->save($url);

 $url='success.xml';

 $name = $_POST['name'];
 $age = $_POST['id'];

 $doc = new DOMDocument();
 $root=$doc->createElement("order");
 $doc->appendChild($root);
 
 $textareaNode = $doc->createElement("name");
 $textNode = $doc->createTextNode($name);
 $textareaNode->appendChild($textNode);
 $root->appendChild($textareaNode); // use $root, not $doc

$doc->getElementsByTagName("order");
//$t = $doc->createElement("title");
$t = $doc->createElement("name");
$t->appendChild($doc->createTextNode($name));

$l = $doc->createElement("age");
$l->appendChild($doc->createTextNode($age));
