Note Submitter: gmail at algofoogle ---- Just in relation to "bishop" and the overall behaviour of array_product... The "empty product" (i.e. product of no values) is supposed to be defined as "1": http://en.wikipedia.org/wiki/Empty_product ...however PHP's array_product() returns int(0) if it is given an empty array. bishop's code does this, too (so it IS a compatible replacement). Ideally, array_product() should probably return int(1). I guess it depends on your specific context or rationale. You might normally presume int(0) to be a suitable return value if there are no inputs, but let's say that you're calculating a price based on "percentage" offsets: $price = 10.0; $discounts = get_array_of_customer_discounts(); $price = $price * array_product($discounts); ...if there are NO "discounts", the price will come out as 0, instead of 10.0
