从关联数组中添加值如果键匹配

Question

我试图在关键字匹配时从关联数组中添加值。最终的目标是要实现这样的输出能力：

Total Ups: 219
Aug. 1 Ups: 105
Aug. 2 Ups: 52
Aug. 3 Ups: 62

我有下面这工作数组值的一笔：

foreach($array as $key => $value){ 
    foreach ($value['report']['daily']['ups'] as $rec){ 
    $upsArr[] = $rec; 
    } 
} 

echo array_sum($upsArr); 

但是，当我试图计算总计一个日期，比如8月1日，我似乎无法完成任何成功的第二级密钥。我有以下，看看是否能得到所需的水平：提前

$array = array(
    array(
    store => 'South', 
    report => array(
     daily => array(
     ups => array('Aug. 1' => '19', 'Aug. 2' => '11', 'Aug. 3' => '13'), 
     sold => array('Aug. 1' => '11', 'Aug. 2' => '5', 'Aug. 3' => '5') 
    )), 
), 
    array(
    store => 'East', 
    report => array(
     daily => array(
     ups => array('Aug. 1' => '38', 'Aug. 2' => '22', 'Aug. 3' => '23'), 
     sold => array('Aug. 1' => '16', 'Aug. 2' => '8', 'Aug. 3' => '8') 
    )), 
), 
    array(
    store => 'West', 
    report => array(
     daily => array(
     ups => array('Aug. 1' => '48', 'Aug. 2' => '19', 'Aug. 3' => '26'), 
     sold => array('Aug. 1' => '28', 'Aug. 2' => '4', 'Aug. 3' => '11') 
    )), 
) 
) 

感谢：

foreach($array as $key => $subArr){ 
    foreach($subArr as $id => $value['report']['daily']['ups'][1]){ 
    print_r($value); 
    } 
} 

这里是我一起工作的阵列。

检查了这一点

$detail = []; 
foreach ($array as $item){ 
    foreach ($item['report']['daily']['ups'] as $date=>$total){ 
     if (!array_key_exists($date, $detail)){ 
      $detail[$date] = $total; 
     }else{ 
      $detail[$date] += $total; 
     } 
    } 
} 
// int 219 
var_dump(array_sum($detail)); 

var_dump($detail); 
/* 
array (size=3) 
'Aug. 1' => int 105 
'Aug. 2' => int 52 
'Aug. 3' => int 62 
*/
