PHP: how to make a sum inside a "for each" cycle?

I've made a foreach loop that print some variables found in an xml file:

foreach ($xml->result->rowset->row as $row)
{
    echo $row["price"] . " " . $row["product"] . "</br>";
}

I would like to get the sum of all the "prices" shown. How can i do?

    echo $row["price"] . " " . $row["product"] . "</br>";

}

Simply add it to a new variable:

$sum = 0;
foreach ($xml->result->rowset->row as $row) {
  echo $row["price"] . " " . $row["product"] . "<br />";
  $sum += $row["price"];
}

echo $sum . "<br />";

Store the count in a variable:

$total = 0;
foreach ($xml->result->rowset->row as $row) {
  echo $row["price"] . " " . $row["product"] . "</br>";
  $total += $row['price']; // assumed row_price is some integer
}
echo $total;

Just have a variable add up those values as you iterate:

$total = 0; // start with zero
foreach ($xml->result->rowset->row as $row)
{
    $total += $row["price"]; // add price to total
    echo $row["price"] . " " . $row["product"] . "</br>";
}
echo $total; // echo out total amount
