How can I create a specified amount of random values that all equal up to a specified number in PHP?

Question

For example, say I enter \'10\' for the amount of values, and \'10000\' as a total amount.

The script would need to randomize 10 different numbers that all equal up

Answer 1

Generate 10 random numbers till 10000 . Sort them from big to small : g0 to g9

g0 = 10000 - r0
g1 = r0 - r1
...
g8 = r8 - r9
g9 = r9

This will yield 10 random numbers over the full range which add up to 10000.
