Answer 1

You need a Processing Instruction

$php = $dom->createProcessingInstruction('php', 'echo $foo->bar;');

Full example:

$dom = new DOMDocument;
$dom->loadXml('');
$dom->getElementsByTagName('body')->item(0)->appendChild(
    $dom->createProcessingInstruction('php', 'echo $foo->bar;')
);
$dom->format = TRUE;
echo $dom->saveXML();

Result:

  
    
  
  
    bar;?>
