    To prevent a parser error when the comment string would contain the character sequence "--", do this:

    <?php

    $CommentString     = 'This contains -- some weird -- characters.';

    $CommentNode = $DomDocument->createComment(
                str_replace('--', '-'.chr(194).chr(173).'-', $CommentString)
    );
    ?>

    This will insert a Soft Hyphen in between the two hyphens which will not cause the parser to error out.

    Use caution: this function does NOT escape, encode, or otherwise change the contents of the string.

    This means that if your string contains two hyphens in a row (--), that will *end* the comment, which can easily create invalid XML when the document is serialized.
