PHP的阵列组 [英] php array group

问题描述

我有以下阵列

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
        )

)

我怎么能组阵列由 ID ？是否有任何PHP函数都可以做到这一点？

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

如果我的foreach 上面的话，我会得到一个重复的，我怎么能避免呢？

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

在上面的例子中 ID 有2项，所以它需要在 ID 里面。

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

编辑：一切正常：但有没有达到同样的一个FOREACH任何方式

推荐答案

有没有原生的，只需使用一个循环。

There is no native one, just use a loop.

$result = array();
foreach ($arr as $data) {
  $id = $data['id'];
  if (isset($result[$id])) {
     $result[$id][] = $data;
  } else {
     $result[$id] = array($data);
  }
}
