array_product

  • We can get the product of an array of integers using a combination of Ruby’s Enumerable#inject method with Fixnum#*.

    PHP

    $numbers = array(2, 2, 2, 2);
$result = array_product($numbers);
print $result;
// => 16

    Ruby

    result = [2, 2, 2, 2].inject {|product, element| product * element }
puts result
# => 16
