get_comment_author_link()

get_comment_author_link() — Retrieves the HTML link to the URL of the author of the current comment. Both get_comment_author_url() and get_comment_author() rely on get_comment(), which falls back to the global comment variable if the $comment_id argument is empty.

Inputs: $comment_id (int|WP_Comment): Optional. WP_Comment or the ID of the comment for which to get the author’s link. Default current comment.

Returns string: The comment author name or HTML link for author’s URL.
