PHP - return value from recursive function

I have function like this:

function show_comments(&$comments, $parent_id = 0) {
      $comments_list = "<ul>\n";
      foreach($comments as $comment) :
        if ($comment["parent_id"] != $parent_id)
          continue;
        $comments_list .= "<li>\n<h2>{$comment['id_comment']}</h2>\n";
        $comments_list .= "<p>$comment[body]</p>\n";


        $this->show_comments($comments, $comment['id_comment']);
        $comments_list .= "</li>\n";
      endforeach;
      $comments_list .= "</ul>\n";

      return $comments_list;
    }

At the moment this function is returning only one result (the first one). How can I bind all result and return them?

On line 10, you call show_comments() but you don't concatenate result.

$comments_list .= $this->show_comments($comments, $comment['id_comment']);
