To add on to the other example, here's how to create an XHTML 1.0 transitional document with head, title, and body elements.

<?php

$document = DOMImplementation::createDocument(null, 'html',
    DOMImplementation::createDocumentType("html", 
        "-//W3C//DTD XHTML 1.0 Transitional//EN", 
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"));
$document->formatOutput = true;

$html = $document->documentElement;
$head = $document->createElement('head');
$title = $document->createElement('title');
$text = $document->createTextNode('Title of Page');
$body = $document->createElement('body');

$title->appendChild($text);
$head->appendChild($title);
$html->appendChild($head);
$html->appendChild($body);

echo $document->saveXML();
?>

This outputs: (http links removed due to spam)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "doctype.dtd"> 
<html xmlns="w3org1999xhtml"> 
  <head> 
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> 
    <title>Title of Page</title> 
  </head> 
  <body></body> 
</html> 

Note the saveXML function. If saveHTML was used instead, you get the output:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "doctype.dtd"> 
<html> 
<head><title>Title of Page</title></head> 
<body></body> 
</html>

To create HTML document with doctype:



<?php

$doctype = DOMImplementation::createDocumentType("html",

                "-//W3C//DTD HTML 4.01//EN",

                "http://www.w3.org/TR/html4/strict.dtd");

$doc = DOMImplementation::createDocument(null, 'html', $doctype);

?>

I just recently got an error, having to do with deprecation, by using the type of calls in the other example listed here.  What I had to do instead looks like this...

$htmldoc = (new DOMImplementation)->createDocument(null, 'html', (new DOMImplementation)->createDocumentType("html"));

This creates a document with <!DOCTYPE html> at the top of it.
