原帖已经结贴。只是获得的结果并不完美，总是最大数999重复太多，显得不够随机，有点假。

$r = foo(32898, 53);echo array_sum($r), PHP_EOL; //验证总和print_r(array_count_values($r)); //查看分布function foo($num, $k, $min=1, $max=999) { $res <span style="color:transparent">/本文来源gaodai#ma#com搞*!代#%^码网%</span><sub>搞代gaodaima码</sub>= array_fill(0, $k, 1); do { for($i=0; $i $max) $t = $max - $res[$i]; if($sum + $t > $num) $t = $num - $sum; $res[$i] += $t; } }while($num > $sum); return $res;}
请修复这个问题，谢谢。
回复讨论(解决方案)
$t = rand(0, $max – $min);
改为
$t = rand(0, $max – $res[$i]);
这样的分布应该很好了
