Al. A factorial of any given integer, , is the product of all positive integers between 1 and 21 inclusive. So, the factorial of 4 is 1 × 2 x 3 x 4 = 24, and the factorial of 5 is 1 × 2 x 3 x 4 × 5 = 120. This can be expressed recursively as follows: O Ifn==0, return 1. (This is the base case) O If n>0, multiply numbers from n down to 1. a. Write a PHP function to display the factorials of the integers up to the given value(argument). Any format could be used for displaying. b. Write the recursive version of the same function to display the factorials of the integers up to the given value(argument). Any format could be used for displaying.

Al. A factorial of any given integer, n, is the product of all positive integers between 1 and n
inclusive.
So, the factorial of 4 is 1 x 2 x 3 x 4 = 24, and the factorial of 5 is 1 x 2 × 3 x 4 x 5 = 120. This
can be expressed recursively as follows:
O If n==0, return 1. (This is the base case)
O If n> 0, multiply numbers from n down to 1.
