For Loop/PHP
Write a class called math. It is to have one property called num. It also has one method called factorial. This method is to start at 1 and multiply all of the integers to num. If num is 5 then you would multiply 12345.
How would you write this as a loop? Would I need to use the for loop or do/while loop?

PHP Factorial Example:
<?php
$n = 5;
$i = 1;
$f = 1;
while($i<$n){
$i = $i + 1;
$f = $f * $i;
}
echo $f;
?>

Here is a java example that finds the factorial of a number.
public class math{
public static long factorial(int n){
if(n <= 1)
return 1;
else
return n * factorial(n - 1);
}
public static void main(String [] args){
int num=5;
System.out.println(factorial(num));
}
}
