Question

I have this code:

foreach ($cartContents as $item => $itemQty)
    echo "$item <br /> $itemQty   <br />  $price";

It loops through some items and prints the name, quantity and price. I would then like to print a total of all the prices added together. Is there a way to get this figure?

Answer 1

Assuming $itemQty and $price are both numeric, this should work:

$total = 0;
foreach ($cartContents as $item => $itemQty) {
    echo "$item <br /> $itemQty   <br />  $price";
    $total += $itemQty * $price;
}

echo "Total: $total<br />";
