Problema MySQL/PHP

[Cyge.]

<?php

$limit = 5; // articoli per pagina

$mysql = new mysqli('localhost', 'pokemonc_01', '*****', 'pokemonc_db');
if(!$mysql)
{
    die("Errore di connessione al database, impossibile procedere");
}

$Comment = strip_tags($_GET['id']);

$result = $mysql->query("SELECT COUNT(*) AS tot FROM articoli")->fetch_assoc();

$page = isset($_GET['p']) ? $_GET['p'] : 1;
$totals = $result['tot'];
$totals_pages = ceil($totals / $limit);

$articles = $mysql->query("
    SELECT
        AR.id AS id,
        AR.title AS title,
        AR.article AS content,
        AU.username AS author,

            }
            ?>
            </table>
        

Pagina <?php echo $page; ?> di <?php echo $totals_pages; ?> 

        <?php
        if($page - 1 > 0)
        {
            echo '[url="./?act=News&p='.($page - 1).'"]&lt; Precedente[/url] | ';
        }else
        {
            echo '&lt; Precedente | ';
        }
        if($page + 1 <= $totals_pages)
        {
                    echo '[url="./?act=News&p='.($page + 1).'"]Successiva &gt;[/url]';
        }else
        {
                    echo 'Successiva &gt;';
        }
        ?>
        </p>

Se io volessi far vedere il numero di commenti scritti, data l'id della news, come dovrei scrivere "$totale"?
