Php 如何在多维数组中按相同值分组并计算和

我试图创建一个简单的报告，显示每月的收入。我想按月分组，计算那个月的总数

这就是阵列的外观：

$payouts = Array
(
    [0] => Stripe\Payout Object
        (
            [id] => po_1F8dyGDi2QUa2pDzir2SvvEJ

这是我的代码，它将以可读的方式为人类显示月份和金额

   <table>
            <thead> 
                                 <tr>
                                    <th>Date Created</th>
                                     <th>Arrival Date</th>
                                      <th>Month</th>
                                       <th>Year</th>
                                  <th>Amount</th>

                                 </tr>
                                 </thead>
                                 <tbody>

                                 <?php 
                                 $totalRevenueBE = 0;
                                 $convertedRBE = 0;
                                 foreach ($payouts->data as $payout) {

                                     $amount_gross = $payout->amount;
                                     $stripe_fee = $payout->fee;
                                     $amount_net = $amount_gross -$stripe_fee;

                                    $convertedAmount = $amount_net / 100;

                                     //calculate total revenue BE
                                    $total = $amount_net;
                                    $totalRevenueBE += $total;  

                                      //convert revenueBE_total to dollars : $1 = 100cents
                                    $convertedRBE = $totalRevenueBE / 100;

                                    //convert unix timestamp to date
                                    $date_created=$payout->created;
                                    $date_available=$payout->arrival_date;
                                    $d_created = date('Y-m-d H:i:s', $date_created);
                                    $d_available = date('Y-m-d H:i:s', $date_available);

                                     ?>
                                        <tr>
                                            <td><?=$d_created?></td>
                                             <td><?=$d_available?></td>

                                                  <td><?=date('Y',strtotime($d_created))?></td>

                                     </tr>
                                    <?php }?>
                                 </tbody>


        </table>

但这是我想要的结果。我想按月分组并计算总数

 Month | Year | Amount
 August| 2019 | 226.3
 July  | 2019 | 747.1

将所需数据移动到另一个数组并使用该数组进行显示
Hi@Random，您可以仅通过使用Mqsql查询获得所需结果，“但这是我想要的结果。”-您的尝试是在哪里获得的？它的具体问题在哪里？请注意，这不是一个代码编写服务，您应该首先表现出合理的努力。非常感谢。这就是答案。我想知道，是否有更动态的方法来访问数组中的值？现在我做的是
foreach（$n_数组作为$n_事务）{echo$n_事务['August']['amount']；}
但是如果我有12个月，这意味着我需要检查数组中是否存在每个月才能访问它？我不想手动访问每个月。Hi随机使用另一个foreach month Year金额
 Month | Year | Amount
 August| 2019 | 226.3
 July  | 2019 | 747.1

move desire data to another array  and use that for display 
 <?php
$data_array=[];  
$month= date('F',strtotime($d_created));
$year=date('Y',strtotime($d_created));

$sum=isset($data_array[$year][$month]['amount'])?$data_array[$year][$month]['amount']:0;
$data_array[$year][$month]['month']=$month;
$data_array[$year][$month]['year']=$year;
$data_array[$year][$month]['amount']=$sum+$convertedAmount;

 echo "<pre>";print_r($data_array); ?
