php - 如何根据php中的键添加数组的总和值

Question

我有一个像这样的 php 数组

Array
(
    [0] => Array
        (
            [Sr_No] => 1
            [Asan_Category] => Warm-Up
            [Asan_Cat_Val] => 8
            [Asan_Sub_Category] => Ankle
            [Asan_Sub_Cat_Val] => 35
            [Asan_Name] => General Ankle Warm up
            [Asan_Name_Val] => 447
            [Prescribed_Steps] => 40
            [Prescribed_Ratio] => 00
            [Actual_Steps] => 12
            [Actual_Ratio] => 0
        )
 [1] => Array
        (
            [Sr_No] => 2
            [Asan_Category] => Warm-Up
            [Asan_Cat_Val] => 8
            [Asan_Sub_Category] => Knee
            [Asan_Sub_Cat_Val] => 111
            [Asan_Name] => General knee warm up
            [Asan_Name_Val] => 464
            [Prescribed_Steps] => 20
            [Prescribed_Ratio] => 00
            [Actual_Steps] => 14
            [Actual_Ratio] => 0
        )
[2] => Array
        (
            [Sr_No] => 1
            [Asan_Category] => Warm-Up
            [Asan_Cat_Val] => 8
            [Asan_Sub_Category] => Ankle
            [Asan_Sub_Cat_Val] => 35
            [Asan_Name] => General Ankle Warm up
            [Asan_Name_Val] => 447
            [Prescribed_Steps] => 40
            [Prescribed_Ratio] => 00
            [Actual_Steps] => 10
            [Actual_Ratio] => 0
        )
[3] => Array
        (
            [Sr_No] => 2
            [Asan_Category] => Warm-Up
            [Asan_Cat_Val] => 8
            [Asan_Sub_Category] => Knee
            [Asan_Sub_Cat_Val] => 111
            [Asan_Name] => General knee warm up
            [Asan_Name_Val] => 464
            [Prescribed_Steps] => 20
            [Prescribed_Ratio] => 00
            [Actual_Steps] => 9
            [Actual_Ratio] => 0
        )
)

The desired output I want 

Array
(
    [0] => Array
        (
            [Asan_Id] => 447
            [Asan_Category] => Warm-Up
            [Asan_Sub_Category] => Ankle
            [Asan_Name] => General Ankle Warm up
            [Prescribed_Steps] => 40
            [Prescribed_Ratio] => 00
            [Total_Steps] => 22
        )

    [1] => Array
        (
            [Asan_Id] => 464
            [Asan_Category] => Warm-Up
            [Asan_Sub_Category] => Knee
            [Asan_Name] => General knee warm up
            [Prescribed_Steps] => 20
            [Prescribed_Ratio] => 00
            [Total_Steps] => 23
        )
)

我希望那些重复的数据成为一个，但它们不同的实际步长与它们的总和成为总步长。 请帮助我，因为我尝试了一些代码但没有像这样成功

    $asan=[];
    $total_steps=0;
    foreach ($aasan_details as $key) {

        $total_steps += $key['Actual_Steps'];
        if(!in_array($key['Asan_Name_Val'],$asan))
        {
            $asan[] = $key['Asan_Name_Val'];

          $lookup[] = array("Asan_Id"=>$key['Asan_Name_Val'],
                      "Asan_Category"=>$key['Asan_Category'],
                      "Asan_Sub_Category"=>$key['Asan_Sub_Category'],
                      "Asan_Name"=>$key['Asan_Name'],
                      "Prescribed_Steps"=>$key['Prescribed_Steps'],
                      "Prescribed_Ratio"=>$key['Prescribed_Ratio'],
                      'Total_Steps'=>$total_steps);
        }


    }

怎么办啊，求大神帮忙

其中 $aasan_details 是我在上面显示的数组和查找数组我得到了唯一值但没有得到它们的总数

最好的解决方案是将其移入数据库并使用查询为您执行该确切操作。

但是，如果您必须在代码中执行此操作，则可以使用键控数组将它们基本上分组，无论需要匹配多少字段才能将它们连接起来:

例如

foreach ..
$consolidated[$item['Asan_Cat_Val']][$item['Asan_Sub_Cat_Val']][] = $item;

然后做几个嵌套循环来遍历这个并总结所有内容。
