#1 Link to reply to comment

Let's display a link to reply to a comment of maximum nesting level - 5, and change the link text to "reply to comment":

$link = get_comment_reply_link( [
	'reply_text' => "reply to comment",
	'respond_id' => 'comment',
	'depth'      => 5,
	'max_depth'  => 10,
], 2881, 631 );

// here we can process the link before it is displayed on the screen
//$link = str_replace( 'foo', 'bar', $link );

echo $link;

Outputs this html code:

<a
 rel='nofollow'
 class='comment-reply-link'
 href='/function/comment_reply_link?replytocom=2881#comment'
 onclick='return addComment.moveForm( "comment-2881", "2881", "comment", "631" )'
 aria-label='Comment on Vladimir's post'
>
reply to comment
</a>
