Choosing n numbers with fixed sum

I m developing a Bot for my Bux system in PHP. the Bot should run N times in a day and each time create variable (random) K users in a manner that sum of users in the day be fixed (M).
How can I achieve this? (Choosing Random number N times that sum of numbers be M).

Answer 1

<?php
function generate_random_sum($sum = 100)
{
    $out = array();
    while(array_sum($out) !== $sum)
    {
        $out[] = mt_rand(1, ($sum - array_sum($out)));
    }
    return $out;
}

print_r(generate_random_sum(100));

这是否有助于?

它将给你一系列不同的价值,在你们的提问中,总价值为M。如果任何人想要自由使用,则无法确定如何创造多少用户。
