在php中从完整路径创建filetree [英] Creating filetree from full path in php

问题描述

我正在尝试从完整路径字符串中创建一些文件树。

这是我使用的php类提供给我：

  /RootFolder/Folder1/File1.doc 
 /RootFolder/Folder1/SubFolder1/File1.txt 
 / RootFolder / Folder2 /SubFolder1/File2.txt 
 /RootFolder/Folder2/SubFolder1/SubSubFolder1/File4.doc 
  

我以为我可以做一个数组：

  array 
（
RootFolder=> array 
（Folder1=> array 
（FILE=>File1.doc
SubFolder1=>File1.txt
SubFolder1 ="File2.txt
）
Folder2=>数组
（
 ... 
）
）
）
  

要最终以< li> 或< table> ：

  RootFolder / 
 | _ Folder1 / 
 | | _ SubFolder1 / 
 | | | _ File1.txt 
 | | | _ File2.txt 
 | | _ File1.doc 
 | 
 | _ Folder2 / 
 | _ SubFolder1 / 
 | _ SubSubFolder1 / 
 | _ File2.txt 
  

我坚持这一点，因为我有点困惑，当然我不是一个开发人员。

还有另一种办法吗？我想我将在页面加载时大约> 10 000个文件字符串继续。

编辑：

其实我有一个php对象，这样返回我的数组：

  Array 
 （
 [0] => Transmission\Model\File Object 
（
 [name：protected] => RootFolder / Folder1 / File1.jpg 
 [size：保护] => 13324 
 [已完成：受保护] => 13324 
 [客户端：保护] => 
）
 
 [1] => Transmission \Model\File对象
（
 [name：protected] => RootFolder / Folder1 / File2.mp3 
 [size：protected] => 10383488 
 [已完成：protected] => 10383488 
 [client：protected] => 
）
 [2] ... 
）
  

我想做的是制作一些文件树表，其名称，大小和状态为curent文件。我基于此 http://labs.abeautifulsite.net/archived/phpFileTree /demo/demo_classic.php 。

有了这个对象，可以使用$ var-> getName（），$ var-> getsize（）和$ var-> isDone（）。

解决方案

strtok 将保存你

 <？php 
 
 $ input = [
'/ RootFolder / Folder1 / File1.doc'，
'/RootFolder/Folder1/SubFolder1/File1.txt'，
'/RootFolder/Folder1/SubFolder1/File2.txt'，
'/ RootFolder / Folder2 /SubFolder1/File2.txt'，
'/RootFolder/Folder2/SubFolder1/SubSubFolder1/File4.doc'，
]; 
 
函数parseInput（$ input）{
 $ result = array（）; 
 
 foreach（$ input AS $ path）{
 $ prev =& $ result; 
 
 $ s = strtok（$ path，'/'）; 
 
 while（（$ next = strtok（'/'））！== false）{
 if（！isset（$ prev [$ s]））{
 $ prev [$ s] = array（）; 
} 
 
 $ prev =& $ prev [$ s]; 
 $ s = $ next; 
} 
 
 $ prev [] = $ s; 
 
 unset（$ prev）; 
} 
 
 return $ result; 
} 
 
 var_dump（parseInput（$ input））; 
  

输出：

 code> array（1）{
 [RootFolder] => 
数组（2）{
 [Folder1] => 
 array（2）{
 [0] => 
 string（9）File1.doc
 [SubFolder1] => 
 array（2）{
 [0] => 
 string（9）File1.txt
 [1] => 
 string（9）File2.txt
} 
} 
 [Folder2] => 
数组（1）{
 [SubFolder1] => 
 array（2）{
 [0] => 
 string（9）File2.txt
 [SubSubFolder1] => 
数组（1）{
 [0] => 
 string（9）File4.doc
} 
} 
} 
} 
} 
  / pre> 
 
 
然后，您可以轻松地使用数组。
 
I'm trying to make some kind of file tree from full path strings.

This is what the php-class I use gives me:
/RootFolder/Folder1/File1.doc
/RootFolder/Folder1/SubFolder1/File1.txt
/RootFolder/Folder2/SubFolder1/File2.txt
/RootFolder/Folder2/SubFolder1/SubSubFolder1/File4.doc
I thought i can make an array like:
array 
(
 "RootFolder" => array 
                ("Folder1" => array
                             ("FILE" => "File1.doc"
                              "SubFolder1" => "File1.txt"
                              "SubFolder1" => "File2.txt"                                  
                             )
                 "Folder2" => array
                             (
                              ...
                              )
                 )             
  )
To finally get to this result with <li> or in a <table>:
RootFolder/
     |_ Folder1/
     |        |_ SubFolder1/
     |        |           |_ File1.txt
     |        |           |_ File2.txt
     |        |_ File1.doc
     |
     |_ Folder2/
              |_ SubFolder1/
                          |_ SubSubFolder1/
                                         |_ File2.txt
I'm stucking on this because i'm a little confused and of course i'm not a dev..

Is there maybe another way to do this? i think i will have about >10 000 file strings to proceed when page is loaded.

EDIT:

In fact i have a php object that returns me arrays like this:
Array
(
[0] => Transmission\Model\File Object
    (
        [name:protected] => RootFolder/Folder1/File1.jpg
        [size:protected] => 13324
        [completed:protected] => 13324
        [client:protected] => 
    )

[1] => Transmission\Model\File Object
    (
        [name:protected] => RootFolder/Folder1/File2.mp3
        [size:protected] => 10383488
        [completed:protected] => 10383488
        [client:protected] => 
    )
[2] ...
)
What i want to do is make some kind of file tree table with the name, the size and status of the curent file. I'm based on this http://labs.abeautifulsite.net/archived/phpFileTree/demo/demo_classic.php.

With this object, details can be retrieved with $var->getName(), $var->getsize() and $var->isDone().
解决方案
strtok will save you.
<?php

$input = [
  '/RootFolder/Folder1/File1.doc',
  '/RootFolder/Folder1/SubFolder1/File1.txt',
  '/RootFolder/Folder1/SubFolder1/File2.txt',
  '/RootFolder/Folder2/SubFolder1/File2.txt',
  '/RootFolder/Folder2/SubFolder1/SubSubFolder1/File4.doc',
];

function parseInput($input) {
  $result = array();

  foreach ($input AS $path) {
    $prev = &$result;

    $s = strtok($path, '/');

    while (($next = strtok('/')) !== false) {
      if (!isset($prev[$s])) {
        $prev[$s] = array();
      }

      $prev = &$prev[$s];
      $s = $next;
    }

    $prev[] = $s;

    unset($prev);
  }

  return $result;
}

var_dump(parseInput($input));
Output :
array(1) {
  ["RootFolder"]=>
  array(2) {
    ["Folder1"]=>
    array(2) {
      [0]=>
      string(9) "File1.doc"
      ["SubFolder1"]=>
      array(2) {
        [0]=>
        string(9) "File1.txt"
        [1]=>
        string(9) "File2.txt"
      }
    }
    ["Folder2"]=>
    array(1) {
      ["SubFolder1"]=>
      array(2) {
        [0]=>
        string(9) "File2.txt"
        ["SubSubFolder1"]=>
        array(1) {
          [0]=>
          string(9) "File4.doc"
        }
      }
    }
  }
}
Then you can use the array as easily as you want.
