$domElement2 = $domDocument->createElement('name', 'GeeksforGeeks'); 
$domElement3 = $domDocument->createElement('address', 'Noida'); 
$domElement4 = $domDocument->createElement('email', 'abc@geeksforgeeks.org'); 
  
// Append element to the document 
$domDocument->appendChild($domComment1); 
  
$domDocument->appendChild($domElement1); 
$domElement1->appendChild($domElement2); 
$domElement1->appendChild($domElement3); 
$domElement1->appendChild($domElement4); 
  
$domDocument->appendChild($domComment2); 
  
// Save the XML file and display it 
echo $domDocument->saveXML(); 
  
?>
輸出:
<?xml version="1.0" encoding="iso-8859-1"?>
