php数组组

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
    )

) 如何将数组分组id？是否有任何本地php函数可用于执行此操作？

如果我foreach以上所述，那么我将得到一个副本，我该如何避免呢？

在上面的示例中id有2个项目，因此它需要位于中id。问题来源于stack overflow
