Add a footnote and other block contents as inline contents using HTML Extended

To accomplish this task, the code can use a placeholder that is replaced with a new WordFragment or the data-type attribute set as 'inline'.

The same snippets can be used when working with HTML Extended and footnotes, comments and endnotes changing the tag name and its properties if needed.

Using a placeholder that is replaced with a new WordFragment:

$html = '
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <table>
        <tbody>
        <tr>
            <td>
                Other text: $FOOTNOTE$
            </td>
        </tr>
        </tbody>
    </table>
</body>
</html>
';
$docx->embedHTML($html, array('useHTMLExtended' => true));

// generate the DOCX as in-memory document to avoid creating a file
CreateDocx::$returnDocxStructure = true;

$documentStructure = $docx->createDocx();

$docxNew = new CreateDocxFromTemplate($documentStructure);

$footnote_html = '
<phpdocx_footnote>
    Some text here and ...
    <phpdocx_footnote_textdocument data-text=" note" data-bold="false" />
    <phpdocx_footnote_textfootnote>
        <p>footnote data</p>
    </phpdocx_footnote_textfootnote>
</phpdocx_footnote>';
$footnote = new WordFragment($docxNew, 'document');
$footnote->embedHTML($footnote_html, array('useHTMLExtended' => true));

$docxNew->replaceVariableByWordFragment(array('FOOTNOTE' => $footnote), array('type' => 'inline'));

CreateDocx::$returnDocxStructure = false;

Using the data-type="inline" attribute:

// as inline contents. Comments, endnotes and footnotes are 'block' as default, set their tags as inline before transforming the HTML contents
unset(HTMLExtended::$tagsBlock['phpdocx_comment']);
unset(HTMLExtended::$tagsBlock['phpdocx_comment_textcomment']);
HTMLExtended::$tagsInline['phpdocx_comment'] = 'addComment';
HTMLExtended::$tagsInline['phpdocx_comment_textcomment'] = 'addCommentTextComment';
unset(HTMLExtended::$tagsBlock['phpdocx_endnote']);
unset(HTMLExtended::$tagsBlock['phpdocx_endnote_textendnote']);
HTMLExtended::$tagsInline['phpdocx_endnote'] = 'addEndnote';
HTMLExtended::$tagsInline['phpdocx_endnote_textendnote'] = 'addEndnoteTextEndnote';
unset(HTMLExtended::$tagsBlock['phpdocx_footnote']);
unset(HTMLExtended::$tagsBlock['phpdocx_footnote_textfootnote']);
HTMLExtended::$tagsInline['phpdocx_footnote'] = 'addFootnote';
HTMLExtended::$tagsInline['phpdocx_footnote_textfootnote'] = 'addFootnoteTextFootnote';

$html = '
