Question

我有一个数组。在做了一些条件后，我得到的数组如下所示。

我的工作是删除任何抵消交易。例如：如果一个成员的积累具有正面和负面，则将其删除。

通过使用此结果数组，我需要根据member_id，transaction_type和transaction_amount进行过滤。（可能是正面的也可能是负面的）。如果member_id和transaction_type相同，那么我需要删除抵消交易。

删除后，生成的数组必须如下所示：

Array
(
   [23] => Array
        (
            [OriginEventId] => 0152c945-e15b-48f9-8a0e-e4b9eace4731
            [Description] => Pension Reversion
            [transaction_date] => 2014-10-30T00:00:00
            [transaction_amount] => -1129794.96
            [member_id] => 1
            [type] => PensionsRolledBack
            [transaction_type] => Pension
        )

   [56] => Array
       (
           [OriginEventId] => 0152c945-e15b-48f9-8a0e-e4b9eace4731
           [Description] => Pension Reversion
           [transaction_date] => 2014-10-30T00:00:00
           [transaction_amount] => 1129794.96
           [member_id] => 2
           [type] => PensionCommencement
          [transaction_type] => Pension
     )
)

我的代码

$total = $array;
    array_walk($array, function($value) use(&$total){
         $result = $this->multiSearch($total, array('transaction_type' =>$value['transaction_type'], 'smsf_actuarial_form_member_id' => $value['smsf_actuarial_form_member_id'], 'transaction_amount' => $value['transaction_amount']));
         pr($result);exit;
    });
public function multiSearch(array $array, array $pairs) {
    $found = array();
    foreach ($array as $aKey => $aVal) {
        $coincidences = 0;
        foreach ($pairs as $pKey => $pVal) {
            if (array_key_exists($pKey, $aVal)) {
                if(is_double($aVal[$pKey]) && is_double($pVal) && abs($aVal[$pKey]) == abs($pVal)){
                    $coincidences++;
                } else if($aVal[$pKey] == $pVal){                        
                    $coincidences++;
                } 
            }
        }
        if ($coincidences == count($pairs)) {
            $found[$aKey] = $aVal;
        }
    }

    return $found;
}

我已根据member_id，transaction_type和transaction_amount进行过滤。

[2] => Array
        (
            [OriginEventId] => 0152c945-e15b-48f9-8a0e-e4b9eace4731
            [Description] => Pension Reversion
            [transaction_date] => 2014-10-30T00:00:00
            [transaction_amount] => -1129794.96
            [smsf_actuarial_form_member_id] => 1
            [type] => InternalTransfers
            [transaction_type] => Accumulation
        )

    [13] => Array
        (
            [OriginEventId] => 0152c945-e15b-48f9-8a0e-e4b9eace4731
            [Description] => Pension Reversion
            [transaction_date] => 2014-10-30T00:00:00
            [transaction_amount] => 1129794.96
            [smsf_actuarial_form_member_id] => 1
            [type] => PensionsRolledBack
            [transaction_type] => Accumulation
        )

如果具有相同的成员ID，交易类型和交易金额，包括正面和负面，那么我需要将其删除。

流量

使用member_id，transaction_type和transaction_amount（正面和负面）过滤数组。
如果结果数组同时具有正数和负数，则将两个数组与已过滤数组取消链接。

条件动态起作用。

要删除数组中的元素，请使用unset函数

foreach ($array as $key => $value) {
    if (isset($array[$key])) {
        foreach ($array as $k => $v) {
            if (
                $value['member_id'] === $v['member_id'] &&
                $value['transaction_type'] === $v['transaction_type'] &&
                $value['transaction_amount'] === -$v['transaction_amount']
            ) {
                unset($array[$key], $array[$k]);
                break;
            }
        }
    }
}
