使用php格式化数组

Question

我有以下具有重复数据的数组：

我想格式化此数组并产生以下数组：

我怎样才能做到这一点。 我重新格式化了简单数组，但是格式化对我来说没有意义。 这让我哭。 请帮我。 如果建议使用任何辅助功能，那将是一件真正的礼物。 提前致谢。

您需要执行以下操作：

<?php
$firstArray = Array
(
    '0' => Array
        (
            'orders' => Array
                (
                    'id' => 9,
                    'name' => 'Abdus Sattar Bhuiyan',
                    'email' => 'sattar.kuet@gmail.com',
                    'mobile' => '01673050495',

注意：-不用担心我放入的数组。 我只是将您的数组格式化为运行目的并在最后检查一下。 谢谢。

Answer 2

对于array_column() （手动参考），这是一个相当简单的工作。 像这样（ $array是您的来源）：

$composite = [];
$composite['orders'] = array_column($array, 'orders')[0];
$composite['order_products'] = array_column($array, 'order_products');
$composite['products'] = array_column($array, 'products');
$composite['psettings'] = array_column($array, 'psettings');

print_r($composite);

这将导致以下数组：

如果需要将多个这样的数组聚合到一个包含所有数组的主数组中，则可以例如将其包装在一个简单的循环中，并为每个复合集添加一个数字索引：

$composite = [];

foreach($arrays as $num=>$array) {
    $composite[$num]['orders'] = array_column... // etc.
}

还要注意手册中提到的array_column的index_key功能，如果要使用订单ID作为主键，可能会派上用场---为此，您必须重新array_column循环逻辑。 让我知道这是否是一个相关问题，我会补充更多； 或按原样足够。
