Hvordan lægges de sammen, så jeg får resultatet af data.lenght og index.lenght?


Koden:

$result = mysql_query("SHOW TABLE STATUS");

while ($row = mysql_fetch_array($result))
{
    $total = $row['Data_length'] + $row['Index_length'];
    $size = ($row[6] + $row[8]);
   

    echo "<br/>";
    echo "<span class=\"bottomtext\">DB størrelse </span>";
    echo "<span class=\"bottomtext\">$total</span>";
    echo "<span class=\"bottomtext\"> Bytes ud af 1.024.000 Bytes</span>";


    echo "<pre>";
    print_r($row);
    echo "</br>";
