I'm fairly new to PHP - programming in general. So basically what I need to accomplish is, create an array of x amount of numbers (created randomly) who's value add up to n:

Lets say, I have to create 4 numbers that add up to 30. I just need the first random dataset. The 4 and 30 here are variables which will be set by the user.

Essentially something like

x = amount of numbers;
n = sum of all x's combined;

create x random numbers which all add up to n;

$row = array(5, 7, 10, 8) // these add up to 30

Also, no duplicates are allowed.

I need the values with an array. I have been messing around with it sometime, however, my knowledge is fairly limited. Any help will be greatly appreciated.

Cheers
