get_comment_author_link( int|WP_Comment $comment_ID )

Retrieve the HTML link to the URL of the author of the current comment.

Description

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.

Parameters

$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.

Return

(string) The comment author name or HTML link for author's URL.

File: wp-includes/comment-template.php

function get_comment_author_link( $comment_ID = 0 ) {
	$comment = get_comment( $comment_ID );
	$url     = get_comment_author_url( $comment );
	$author  = get_comment_author( $comment );

	if ( empty( $url ) || 'http://' == $url ) {
		$return = $author;
	} else {
		$return = "<a href='$url' rel='external nofollow' class='url'>$author</a>";
	}
