如何形成一个PHP树菜单？ [英] How to form a PHP tree menu?

问题描述

我有一些路径存储在我的数据库中作为：它们是未排序的，可以是任何长度。

--------路径---- ----

C：/ devices / data1

< devices / data1 / application2

C：/ devices / data1 / application1

< application3

C：/ devices / data2 / application2

C：/ devices / data2 / application1

C：/ devices / data1 / application3

  C>装置> data1> application1 
 application2 
 application3 
 data2> application1 
 application2 
 application3 
  

您能帮我解决这个问题吗？ / p>

希望快速回复。非常感谢！

Ulvund的解决方案适用于我，但现在我需要生成指向href标签的链接：

我尝试了以下操作：

请帮助我删除额外的节点：它当前生成...

 
 C：/ devices / data1 
 data1 / application1 
 application2 
 application3 
 data2 
 data2 / application1 
 application2 
 application3 
 

解决方案

  $ 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; 
 
 
函数to_tree（& $ multifruit，$ fruit）{
 if（count（$ fruit）> 2）{
 $ shifted = array_shift水果）; 
 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）;

I have some paths stored in my db as: They are unsorted and can be any length.

--------Paths--------

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

I need to form a menu as below:

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

Could you please help me solve this problem?

Wish for some quick responses. Thanks!

Ulvund's solution works for me but now I need to generate the links to the href tags:

I tried the following:

http://www.pbalan01.0fees.net/god1.php

Please help me remove the extra node: it currently generates...

C:/devices/data1
           data1/application1
                 application2
                 application3
           data2
           data2/application1
                 application2
                 application3

解决方案

$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);
/* Result
Array
(
    [C:] => Array
        (
            [devices] => Array
                (
                    [0] => data1
                    [data1] => Array
                        (
                            [0] => application1
                            [1] => application2
                            [2] => application3
                        )

                    [data2] => Array
                        (
                            [0] => application1
                            [1] => application2
                            [2] => application3
                        )

                )

        )

)
