Displays the permalink anchor for the current post.

The permalink mode title will use the post title for the ‘a’ element ‘id’
attribute. The id mode uses ‘post-‘ with the post ID for the ‘id’ attribute.

function permalink_anchor( $mode = 'id' ) {
	$post = get_post();
	switch ( strtolower( $mode ) ) {
		case 'title':
			$title = sanitize_title( $post->post_title ) . '-' . $post->ID;
			echo '';
			break;
		case 'id':
		default:
			echo '';
			break;
	}
}
