Question

我在循环中遇到了正确计算的问题。右下方是要翻转的原始数组。查看数组的第二个dd的结果。正如你所看到的，这个值已经被排序了。这就是foreach循环中出现的问题。即使我的预期结果很简单，我的逻辑似乎也很混乱。请看下面的结果。希望有人能帮助我找出最简单的方法来获得预期的输出。

我试图更改密钥1.401和1.501，以避免与索引的迭代冲突。

  array:5 [▼
       "1.4"   => 40 
       "1.401" => 42 
       "1.5"   => 38 
       "1.501" => 39 
       "1.6"   => 41 
    ]
    $count1 = 0;
    foreach ($scho as $scholar_id2) {
        $scholar = Scholar::find($scholar_id2);
        $crits = New Criteria;
        $crits->scholar_id = $scholar->scholar_id;
        $crits->scholarship_id = $scholarship_id;
        $crits->save();
        $count1++;
    }

索引和值的翻转数组的结果

array:5 [▼
    "40" => 1.4
    "42" => 1.4
    "38" => 1.5
    "39" => 1.5
    "41" => 1.6
]
    $list1 = Criteria::where('scholarship_id','=',$scholarship->scholarship_id)->get();
    $all_id = [];
    foreach ($list1 as $id) {
        array_push($all_id, $id->criteria_id);
    }

        $last_scholar_gpa = 0;
        $percentage = 1.2;
        foreach ($all_id as $id2) {
        $crits = Criteria::find($id2);
        foreach ($all_list_GPA as $scholar_GPA) {

        if($percentage > 0.5 && $last_scholar_gpa != $scholar_GPA)
        $percentage = $percentage - 0.1;

        $total_points_two = $scholarship->scholarship_points_two * $percentage;
        $crits->criteria_gpa = $total_points_two;
        }

        $crits->save();

        $last_scholar_gpa = $scholar_GPA;

    }

这是scholarship_points_two = 25

的值

这应该是结果：

id    criteria_gpa
40          25.00
42          25.00
38          22.50
39          22.50
41          20.00

保存在数据库中的当前结果（但计算错误）

id    criteria_gpa
40          22.50
42          17.50
38          12.50
39          7.50
41          2.50
