Creating filetree from full path in php

Question

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().

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.
