如何获取数组的重复数字部分

Question

print_r($_POST['Receipt']['name'])

给了我一个像这样的数组

Array (
    [Donations] => Array (
        [name] => Donations
    )
    [Fees] => Array (
        [ledger] => Fees
    )
    [100] => Array (
        [amount] => 100
    )
    [Others] => Array (
        [name] => Others
    )
)

这里两个重复的数值100和费用（它们分别是字段数量和分类帐的值）是我想要存储在数组中的值。我试过这样的事情

foreach ($_POST['Receipt']['name'] as $item)
        {   

            if (isset($item['amount']))
            {
                $amount[]= $item['amount'];
            }
            if (isset($item['ledger']))
            {
                $ledger[]= $item['ledger'];
            }

        }

但$ ledger []和$ amount []不会存储它们的重复值。对于amounnt []，它只存储[amount] => 100中的100并且不会将{100}存储在[100] => Array中如何将重复值存储在此数组中？

Answer 1

试试这个

foreach ($_POST['Receipt']['name'] as $item)
    {   

        if (isset($item['100']))
        {
            $amount[]= $item['100']['amount'];
        }
        if (isset($item['fees']))
        {
            $ledger[]= $item['fees']['ledger'];
        }

    }
