Comment

Comments can be added to a document by using addComment. The comment can contain formatted text. Once the comment has been added, it can be linked to any element with setCommentRangeStart.

<?php

// first create a comment
$comment= new \PhpOffice\PhpWord\Element\Comment('Authors name', new \DateTime(), 'my_initials');
$comment->addText('Test', array('bold' => true));

// add it to the document
$phpWord->addComment($comment);

$textrun = $section->addTextRun();
$textrun->addText('This ');
$text = $textrun->addText('is');
// link the comment to the text you just created
$text->setCommentRangeStart($comment);
$textrun->addText(' a test');

If no end is set for a comment using the setCommentRangeEnd, the comment will be ended automatically at the end of the element it is started on.

The ODF writer serializes comments as native ODF annotations, including the author, date, formatted content, and comment range.
