    Update a link

    wp_insert_link() will update a link – instead of inserting it – if you provide the link’s ID.

    <?php
    $linkdata = array(
	'link_id'   => 7,
	'link_name' => 'WordPress Code Reference',
	'link_url'  => 'https://developer.wordpress.org/reference'
    );

    $link_id = wp_insert_link( $linkdata );
?>
