Question

    echo "<pre>";
    print_r($data);
    echo "</pre>";

    Array
    (
        [0] => Array
            (
                [Deposit] => Array
                    (
                        [id] => 63393
                        [amount] => 200.00
                        [date] => 2014-06-17 08:40:13
                        [details] => 
                    )

                [User] => Array
                    (
                        [username] => presido490
                        [group_id] => 1
                    )

            )
    )

如何移动[username] =＆gt;来自[User]的presido490 =＆gt; Array（）到[Deposit] =＆gt; Array（），我需要输出

Array
(
    [0] => Array
        (
            [Deposit] => Array
                (
                    [id] => 63393
                    [amount] => 200.00
                    [date] => 2014-06-17 08:40:13
                    [username] => presido490
                    [details] => 
                )

            [User] => Array
                (
                    [group_id] => 1
                )

        )
)

Answer 1

在简单的循环中完成

foreach($dataas $key => $element) {
    $data[$key]['Deposit']['username'] = $data[$key]['User']['username'];
    unset($data[$key]['User']['username']);
}

如果您愿意，可以在array_walk（）或array_map（）而不是循环中执行此操作

修改

如果您必须在username和date之间定位details（建议您首先不了解如何使用数组数据）。

foreach($dataas $key => $element) { $data[$key]['Deposit'] = array( 'id' => $data[$key]['Deposit']['id'], 'amount' => $data[$key]['Deposit']['amount'], 'date' => $data[$key]['Deposit']['date'], 'username' => $data[$key]['User']['username'], 'details' => $data[$key]['Deposit']['details'], ); unset($data[$key]['User']['username']); }

但除了增加开销
之外，这根本不会对你的代码产生任何影响

将数组中的数组移动到php中的父数组
