PHP Manual: Calculate the product of values in an array

intfloat array_product(array $array)

array_product returns the product of values in an array.

Returns the product as an integer or float.

Version	Description
8.3.0	Now emits `E_WARNING` when `array` values cannot be converted to int or float. Previously arrays and objects where ignored whilst every other value was cast to int. Moreover, objects that define a numeric cast (e.g. GMP) are now cast instead of ignored.

Example #1 array_product examples

<?php

$a = array(2, 4, 6, 8);
echo "product(a) = " . array_product($a) . "\n";
echo "product(array()) = " . array_product(array()) . "\n";

?>

The above example will output:

product(a) = 384
product(array()) = 1
