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 `

` or in a ``: ``` 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] => Tran…

`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.
