Question

我在PHP中有这个数组。但我想提取数组的每个项目并将其放在外部数组中，如下所示：

[PordersProduct] => Array
(
    [0] => Array
    (
        [1] => Array
        (
            [product_id] => 300001300
            [Product] => Array
                (
                    [name] => RELLENO CARNE P/ EMPANADA X KG
                )

            [requested] => 2.500
            [formula_quantity] => 0
            [cep_quantity] => 35.723
            [wr_semi_finished_quantity] => 0
            [in_execution_quantity] => 7488.131
            [wr_total_semi_finished_quantity] => 7523.854
            [to_produced_orders_quantity] => 0
        )

    )

    [1] => Array
    (
        [0] => Array
        (
            [product_id] => 300002841
            [Product] => Array
                (
                    [name] => DISCO PARA EMPANDAS  DE  85 GRS POR UNIDAD
                )

            [requested] => 50
            [formula_quantity] => 0
            [cep_quantity] => 0
            [wr_semi_finished_quantity] => 0
            [in_execution_quantity] => 7925
            [wr_total_semi_finished_quantity] => 7925
            [to_produced_orders_quantity] => 0
        )

    )

)

但我希望它是这样的：

[PordersProduct] => Array
(
[0] => Array
    (

        [product_id] => 300001300
        [Product] => Array
            (
                [name] => RELLENO CARNE P/ EMPANADA X KG
            )

        [requested] => 2.500
        [formula_quantity] => 0
        [cep_quantity] => 35.723
        [wr_semi_finished_quantity] => 0
        [in_execution_quantity] => 7488.131
        [wr_total_semi_finished_quantity] => 7523.854
        [to_produced_orders_quantity] => 0

    )

[1] => Array
    (

        [product_id] => 300002841
        [Product] => Array
            (
                [name] => DISCO PARA EMPANDAS  DE  85 GRS POR UNIDAD
            )

        [requested] => 50
        [formula_quantity] => 0
        [cep_quantity] => 0
        [wr_semi_finished_quantity] => 0
        [in_execution_quantity] => 7925
        [wr_total_semi_finished_quantity] => 7925
        [to_produced_orders_quantity] => 0

    )

)

我该怎么做？

我试过这个：

grouped_data_porders2 = array(); // other array
    foreach ($grouped_data_porders['PordersProduct'] as $key => $item) {
                $grouped_data_porders2['PordersProduct'][] = $item[$key];
            }
            $grouped_data_porders['PordersProduct'] = $grouped_data_porders2['PordersProduct'];

但它不起作用，请你帮我。

由于

Answer 1

你可以试试这个：

$data = [];
$newdata = [];
foreach($data as $item){
    $newdata[] = $item[0];
}

更新：也请查看@ uri-goren的回答。它的概念相同但更短。

更新2： @ uri-goren似乎改变了他的回答。它是这样的：

$newdata = array_map(function($item){
        return $item[0];
    }, $data);

这是使用PHP的array_map函数，它遍历数组并将每个值发送到自定义函数并返回一个新数组，其中包含函数给出的值。它需要函数的名称或anonymous function以及一个或多个数组。
