Question

I have one query where the output processing looks like this:

 while($row = mysql_fetch_array($result)){
    echo $row['username'] . " " . $row['earning'];
 }

And outputs result is like this:

 JOHN  200
 JOHN  350
 NEO   100
 NEO   220

What I want to achieve is that every name appears once, and “earning” is sum of all earnings of that name, like this:

 JOHN 550
 NEO  320

I have to mention that I CANNOT change the query; that is biggest problem.

Is there any hope? Some suggestions? 🙂

Answer 1

You can sum the values in the loop to another array and then output it.

Try:

$earnings = array();

while($row = mysql_fetch_array($result)) {
    if (!isset($earnings[$row['username']])) $earnings[$row['username']] = 0;
    $earnings[$row['username']] += $row['earning'];
}

foreach($earnings as $user => $earnings) {
    echo "$user  $earnings<br />\n";
}
