68. PHP Program to find all the Factorial Prime numbers from 1 to 99.
How does this program work?
- This program is used to find all the factorial prime numbers from 1 to 99 using PHP.
- Prime number means which is only divisible by 1 and that number itself, and cannot divisible by any other number.
- First store the number into variable, then we will find the remainder using loop.
- The counter will be increment if remainder zero, Once number can be divisible by some other number instead of 1 and that number itself, If its value less than three means its a primer number.
