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

maybe something like this:

set max amount remaining to the target number

loop for 1 to the number of values you want - 1

get a random number from 0 to the max amount remaining

set new max amount remaining to old max amount remaining minus the current random number

repeat loop

you will end up with a 'remainder' so the last number is determined by whatever is left over to make up the original total.
