在php中从完整路径创建文件树

Question

我正在尝试从完整路径字符串创建某种文件树。

这是我使用的 php-class 给我的：

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

我想我可以制作一个像这样的数组：

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

使用<li> 或<table> 最终得到这个结果：

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

我坚持这个是因为我有点困惑，当然我不是开发人员..

是否有其他方法可以做到这一点？我想当页面加载时我将有超过 10 000 个文件字符串继续进行。

编辑：

事实上我有一个 php 对象，它返回我这样的数组：

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] ...
)

我想做的是用当前文件的名称、大小和状态制作某种文件树表。我基于这个http://labs.abeautifulsite.net/archived/phpFileTree/demo/demo_classic.php。

使用此对象，可以使用 $var->getName()、$var->getsize() 和 $var->isDone() 检索详细信息。

strtok会救你。

<?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',
];

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));

输出：

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"
        }
      }
    }
  }
}

然后你就可以随心所欲地使用数组了。

您只需将根文件夹的路径传递给下一个函数即可：

<?php
$path = 'RootFolder';
ListFolder($path);

    function ListFolder($path){
        //using the opendir function
        $dir_handle = @opendir($path) or die("Unable to open $path");

        //Leave only the lastest folder name
        $explode = explode("/", $path);
        $dirname = end($explode);

        //display the target folder.
        echo ("<li>$dirname\n");
        echo "<ul>\n";
        while (false !== ($file = readdir($dir_handle))) {
            if($file!="." && $file!=".."){
                if (is_dir($path."/".$file)){
                    //Display a list of sub folders.
                    ListFolder($path."/".$file);
                }else{
                    //Display a list of files.
                    echo "<li>$file</li>";
                }
            }
        }
        echo "</ul>\n";
        echo "</li>\n";

        //closing the directory
        closedir($dir_handle);
    }
?>
