Подскажите что делает этот запрос в MySQL
  $this->count_1 = mysql_query("SELECT count(id) AS number FROM $this->table") or die ("Query failed!");
         while ($count = mysql_fetch_array($this->count_1)) {
                    $total_entries = $count["number"];
              }
И еще один запрос
$this->tort = mysql_query("SELECT id, name, email, message, date FROM $this->table ORDER BY id DESC LIMIT $offset, $per_page") or die ("Query failed!");
              while ($row = mysql_fetch_array($this->tort))
