Question

is that possible to output the summary of INT variables in (mysql_fetch_array)?

$result=mysql_query("SELECT numbers FROM table ORDER BY rand() LIMIT 3");
while ($row = mysql_fetch_array($result)) {
echo $row['number'] . "<br/>";
}

the output would be like this:

23
37
31

The question is can i output the sumarry of this three results in the same while loop? Which it’s “91”.

Answer 1

Why in the same loop? Why not just do something like this?

        //initialise your variable
        $total = 0;
    $result=mysql_query("SELECT numbers FROM table ORDER BY rand() LIMIT 3");
    while ($row = mysql_fetch_array($result)) {
    echo $row['number'] . "<br/>";
        //running total
        $total = $total + $row['number'];
    }
        //output it
        echo "total = " . $total;
