$project
  ->appendChild($document->createElementNS($xmlns, 'licenses')) 
  ->appendChild($document->createElementNS($xmlns, 'license')) 
  ->appendChild($document->createElementNS($xmlns, 'url')) 
  ->appendChild($document->createTextNode($text6));
   ->appendChild($document->createElementNS($xmlns, 'name')) 
  ->appendChild($document->createTextNode($text7));
 

$document->save("d.xml");

?>

</div>

PHP supports the DOM 3 Api. You create nodes and append them to the document.

The XML in your question uses a namespace, so you have to create nodes for this namespace (use the *NS variants of the methods). This adds namespace definitions as needed.

$xmlns = 'http://maven.apache.org/POM/4.0';
$document = new DOMDocument();
$project = $document
  ->appendChild($document->createElementNS($xmlns, 'project'));
$project->setAttributeNS(
  'http://www.w3.org/2001/XMLSchema-instance',  
  'xsi:schemaLocation',
  'http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd'
);
$project
  ->appendChild($document->createElementNS($xmlns, 'model'))
  ->appendChild($document->createTextNode('4.0.0'));

$document->formatOutput = TRUE;
echo $document->saveXml();
