multiply two array values in php [closed]

Answer 1

The following will work as long as both arrays are the same size.

for($i = 0; $i < count($qty); $i++) {
    $result[] = $qty[$i] * $price[$i];
}

The result will be in the $result array.

To get the sum:

echo "sum(result) = " . array_sum($result) . "\n";
