如何按列值对子数组进行分组? [英] How to group subarrays by a column value?

问题描述

我有以下数组

Array
(
    [0] => Array
        (
            [id] => 96
            [shipping_no] => 212755-1
            [part_no] => reterty
            [description] => tyrfyt
            [packaging_type] => PC
        )

    [1] => Array
        (
            [id] => 96
            [shipping_no] => 212755-1
            [part_no] => dftgtryh
            [description] => dfhgfyh
            [packaging_type] => PC
        )

    [2] => Array
        (
            [id] => 97
            [shipping_no] => 212755-2
            [part_no] => ZeoDark
            [description] => s%c%s%c%s
            [packaging_type] => PC
        )

)

如何按id对数组进行分组?是否有任何本地php函数可用于执行此操作?

How can I group the array by id? Is there any native php functions are available to do this?

如果我foreach以上内容，我将得到一个副本，该如何避免呢?

If I foreach the above then I will get a duplicate one, how can I avoid that?

在上面的示例中，id有2个项目，因此它必须位于id内.

On the above example id have 2 items, so its need to be inside of the id.

所有工作都很好:但有什么方法可以一次实现相同的目标吗?

推荐答案

没有原生的，只需使用循环即可.

There is no native one, just use a loop.

$result = array();
foreach ($data as $element) {
    $result[$element['id']][] = $element;
}
