Math: Product (multiplication)

Product (multiplication) of $a and $b. A can be an array and $b a number, in which case each member of $a gets multiplied by $b. If $a is an array and $b is not provided then array_product is used to return a single numeric value. If both $a and $b are arrays, each member of $a is multiplied against the corresponding member in $b compared using index.
