In the above two programs, we didn’t wrap the logic within a function. ), is the product of all positive integers less than or equal to n. For example – 5! When a function calls itself is termed as recursion. } =1; $x--) { $factorial = $factorial * $x; } echo "Factorial of $num is $factorial"; ?> Output Factorial of 4 is 24 Get all the numbers starting from 1 up to that number. It is denoted by n! } The Factorial formula is generally defined as the product of given number with all lowest vale numbers. An integral domain is factorial if and only if its multiplicative semi-group is Gaussian (see Gauss semi-group ), and for this reason factorial rings are also called Gaussian rings or Gauss rings. A Simple Solution solution is to initialize sum as 0, then run a loop and call factorial function inside the loop.. © Copyright 2011-2018 www.javatpoint.com. The name of the function is calculate_fact that will be used to calculate the factorial. . echo '
