# PHP for loop Exercises: Calculate and print the factorial of a number using a for loop

## PHP for loop: Exercise-5 with Solution

Write a program to calculate and print the factorial of a number using a for loop. The factorial of a number is the product of all integers up to and including that number, so the factorial of 4 is 4*3*2*1= 24.

**Pictorial Presentation: **
