仓位分配未分配权利金额

Question

早上好，我有一个数组，可以包含4到4000个条目，我必须在4个人之间平均分配数量。我正在努力使我的代码按需执行，

您可以看到我对数组的分配不是所期望的。

Array（[0] => Array（[0] => 80 [7] => 40 [8] => 50）[1] => Array（[1] => 80）[2] =>数组（[2] => 70 [6] => 30）[3] =>数组（[3] =>60 [5] => 40））

数组0共有150数组1共有80个数组2共有100数组3的总数为100

<?php
arrayBuilder();
function arrayBuilder()
{
    $list_of_items = [80, 20, 30, 40, 50, 60, 70, 80];
    rsort($list_of_items);
    $number_of_cont = 4;
    $weight_of_items = array_sum($list_of_items);
    $weight_per_cont = ($weight_of_items/$number_of_cont);
    $containers = [];
    $sumArray = $newArray = [];
    $containersSorted = buildArray($list_of_items,$number_of_cont,$containers,$weight_per_cont);
    $itemsNotAdded = itemsNotINArray($list_of_items, $containersSorted);
    foreach ($containersSorted as $k => $subArray) {
        foreach ($subArray as $id => $value) {
            if(isset($sumArray[$k])) {
                $sumArray[$k] += $value;
            }else{
                $sumArray[$k] = $value;
            }
        }
    }
    sort($sumArray);
    $itemsNotAdded = array_values($itemsNotAdded);
    foreach($itemsNotAdded as $key => $value){
        foreach($sumArray as $minkey => $minval){
            if($minkey == $key) {
                $containersSorted[$key][] = $value;
                unset($itemsNotAdded[$key]);
            }
        }
    }

    print_r($containersSorted);
};

function itemsNotINArray($list_of_items, $containersSorted){
    foreach($containersSorted as $conid => $conval){
        foreach($list_of_items as $key => $value){
            if(key_exists($key,$conval)){
               unset($list_of_items[$key]);
               continue;
            }
        }
    }
    return $list_of_items;
};

  function getMisMatchKey($itemsNotAdded, $containersSorted){

  }

  function buildArray($list_of_items,$number_of_cont,$containers, 
  $weight_per_cont){
    foreach($list_of_items as $key => $item) {
        for ($i = 0; $i < $number_of_cont; $i++) {
            $total = (isset($containers[$i])) ? array_sum($containers[$i]) : 0;
            if (($total + $item) < $weight_per_cont) {
                $containers[$i][$key] = $item;
                break;
            }
        }
    }
    return $containers;

};
?>

应该均匀地解决

数组（[0] =>数组（[0] => 80 [7] => 20）[1] =>数组（[1] =>80 [6] => 30）[2] =>数组（[2] => 70 [8] => 40）[3] =>数组（[3] => 60 [5] => 50]

您可以使用array_chunk将一个数组的数据平均分布到许多其他数组+最后一个数组，而该数组可能少于其他数组。
