PHP數組總和為相同的值

Question

我有這個數組：

Array ( [0] => 
       Array ( 
        [0] => Array ( 
          [07] => Array ( 
               [2] => 352.9
               [3] => 375737
               [4] => 1000000002
           ) ) 
        [1] => Array ( 
           [07] => Array ( 
               [2] => 362.1
               [3] => 375797
               [4] => 1000000002
        ) ) 
)
Array ( [1] => 
        [0] => Array ( 
           [08] => Array ( 
               [2] => 305.7
               [3] => 375857
               [4] => 1000000002
        ) )
    )
)

我需要鍵07（是month）的最終數組總和，如下所示：

Array ( [0] => 
     Array ( 
            [0] => Array ( 
              [07] => Array ( 
                   [2] => 3254.9 ( the sum of each 07 )
                   [3] => 6521545 ( the sum )
                   [4] => 98474916521621 ( the sum )
               ) ) 
)
Array ( [1] => 
            [0] => Array ( 
              [08] => Array ( 
                   [2] => 305.7 ( not summed cause month 08 is only one )
                   [3] => 375857 ""
                   [4] => 1000000002 ""
               ) ) 
    )
)

有什么幫助嗎？

在這里，嘗試一下-我確定它既不是完美的解決方案也不是最佳解決方案（3 foreach-es），但是它可以在相當大的數據集上工作...

$ inputArray是包含您提供的數據的多維數組，順便說一句...

編輯：固定版本：

$result = array();

foreach( $inputArray as $subArray ) {

    foreach ( $subArray as $subKey => $member ) {

        if ( empty( $result[$subKey]) ) {

            $result[$subKey] = $member;

        } else {
            foreach ( $member as $id => $subMember ) {

                if ( empty( $result[$subKey][$id]) ) {

                    $result[$subKey][$id] = $subMember;

                } else {

                    $result[$subKey][$id] += $subMember;

                }
            }
        }
    }
}

EDIT2：由於您更改了數組的格式，解決方案是不同的：

注意：$ array1和$ array2是您的“全局”-預定義數組。

$arrayWrapper = array_merge( ( array ) $array1, ( array ) $array2 );

$result = array();

foreach ( $arrayWrapper as $inputArray ) {

    foreach( $inputArray as $subArray ) {

        foreach ( $subArray as $subKey => $member ) {

            if ( empty( $result[$subKey]) ) {

                $result[$subKey] = $member;

            } else {
                foreach ( $member as $id => $subMember ) {

                    if ( empty( $result[$subKey][$id]) ) {

                        $result[$subKey][$id] = $subMember;

                    } else {

                        $result[$subKey][$id] += $subMember;

                    }
                }
            }
        }
    }
}

用您的數據對其進行測試，應該可以正常工作。

干杯。
