<?php
require 'class/db.php';
 
$sql = "select  from information_schema.tables where table_schema='ecshop' and table_type='base table' order by TABLE_ROWS desc ";
 
$arr = $db->queryArray($sql);
 
//var_dump($arr);
foreach ($arr as $k => $v) {
 $tbname = $v->TABLE_NAME;
 $rows = $v->TABLE_ROWS;
 echo $tbname.' - ';
 echo $rows;
 echo '<br>';
}
?>
