How do I append to the end of the comments array in WordPress?

I'm trying to include something at the end of the comments array for a WordPress plugin.

I currently have add_filter('comments_array', 'my_function'), where my_function($comments='') is something along the lines of:

my_function($comments='') {
  echo 'something';

  return $comments;
}

I obviously can't return the comments first, and echoing them doesn't work because $comments is a multi-dimensional array. Is there some way I can print the WordPress comme开发者_StackOverflow中文版nts and then append something to them?

Thanks.

You want to add something that looks like a comment or add arbitrary html under each comment block?

Can you add to the page template(s) what you want to appear under the comments block? I.e.,

<?php comments_template(); ?>

html or php here

<?php endwhile; else: ?>
