将字符串分解为多级对象（或数组）

Question

我有这样一个字符串：-

dev/clients/518/aaa/1915/bbb/1/file.pdf

我的目标是能够通过多级对象

引用file.pdf

dev->clients->518->aaa->1915->bbb->1

或数组

[dev][clients][518][aaa][1915][bbb][1]

这是来自 AWS S3 的密钥，我试图从中创建一个可导航的结构。我可以分解字符串得到

Array
(
    [0] => dev
    [1] => clients
    [2] => 518
    [3] => aaa
    [4] => 1915
    [5] => bbb
    [6] => 1
    [7] =>file.pdf
)

不确定如何从这里前进。这可能会更好地显示我想要的东西：-

Array (
    [dev] => Array (
        [clients]  => Array (
            [518] => Array (
                [aaa] => Array (
                    [1915] => Array (
                        [bbb] => Array (
                            [1] => file.pdf
                        )   
                    )
                )   
            )
        )
    )
)

你可以用简单的方法做到这一点 for-loop:

$arr = explode("/", "dev/clients/518/aaa/1915/bbb/1/file.pdf");
$arr = array_reverse($arr); //reverse the order to start from the lowest level
$res = array_shift($arr); //init the result as the last element ("file")
foreach($arr as $e) {
    $tmp[$e] = $res;
    $res = $tmp;
    unset($tmp[$e]); //so $tmp will not contain dragging element
}

您希望输出在 $res

将字符串分解为多级对象（或数组）

Break String in to multilevel object (or array)

php

arrays

object

explode
