PHP：将带有重复键的列表转换为多维数组

Question

我有一个如下所示的键值列表：

running: "yes"
running_where: "to the store"
running_why: "because"
walking: "yes"
someotherkey: "some non related value"
walking_where: "over there"
walking_why: "mom told me to"
running: "yes"
running_where: "to the bank"
yetanotherkey: "yet another non related value"
running_why: "broke"

等等。分组是有序的（但有时我想完全忽略分组中的其他键），并且我想通过对相关项进行分组将其转换为可用的数组，在上面的情况下会给我： / p>

Array
(
    [0] => Group
        (
            [running] => yes
            [running_where] => to the store
            [running_why] => because
        )

    [1] => Group
        (
            [walking] => yes
            [walking_where] => over there
            [walking_why] => mom told me to
        )
    [2] => Group
        (
            [running] => yes
            [running_where] => to the bank
            [running_why] => broke
        )        
 )

PHP中最简单的方法是什么？我已经看过类似的问题，但尚未找到适用的问题。

Answer 1

试试这段代码，

array_chunk($array, 3);
