    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.
