如何形成一个PHP树形菜单？ [关闭]

Question

我的数据库中存储了一些路径：它们未排序，可以是任意长度。

--------路径--------

C:/devices/data1

C:/devices/data1/application2

C:/devices/data1/application1

C:/devices/data2/application3

C:/devices/data2/application2

C:/devices/data2/application1

C:/devices/data1/application3

我需要形成如下菜单：

C > devices > data1> application1 
                     application2 
                     application3 
              data2> application1 
                     application2 
                     application3 

你能帮我解决这个问题吗？

希望得到一些快速响应。谢谢！

Ulvund 的解决方案对我有用，但现在我需要生成指向 href 标记的链接：

我尝试了以下方法：

请帮我删除多余的节点：它当前生成...

C：/设备/数据1 数据1/应用程序1 应用2 应用3 数据2 数据2/应用程序1 应用2 应用3

$paths[] = "C:/devices/data1";
$paths[] = "C:/devices/data1/application2";
$paths[] = "C:/devices/data1/application1";
$paths[] = "C:/devices/data2/application3";
$paths[] = "C:/devices/data2/application2";
$paths[] = "C:/devices/data2/application1";
$paths[] = "C:/devices/data1/application3";


function to_tree(&$multifruit, $fruit) {
    if (count($fruit)>2) {
        $shifted = array_shift($fruit);
        to_tree($multifruit[$shifted], $fruit);
        return $multifruit;
    } else {
        return $multifruit[$fruit[0]][] = $fruit[1];
    }   
}   

sort($paths);
foreach($paths as $path) {
   $path = explode("/",$path);
   to_tree($multifruit, $path);
}   

print_r($multifruit);

代码

<?php

$rows = array(
    'C:/devices/data1',
    'C:/devices/data1/application2',
    'C:/devices/data1/application1',
    'C:/devices/data2/application3',
    'C:/devices/data2/application2',
    'C:/devices/data2/application1',
    'C:/devices/data1/application3',
);
sort($rows);

$sorted = array();
foreach ($rows as $row) {
    eval('$sorted["' . implode('"]["', explode('/', $row)) . '"] = array();');
}
print_r($sorted);

?>

输出

Array
(
    [C:] => Array
        (
            [devices] => Array
                (

                        (
                            [application1] => Array
                                (
                                )
                            [application2] => Array
                                (
                                )
