Multidimensional array of string

Let's say I have this row that I want to place in a multidimensional array.

Edit: the number of subfolders in a row is dynamic .. from zero subfolders to 10

<?php
       $string ="Folder1/Folder2/Folder3/filename1\n";
       $string .=" Folder1/Folder2/Folder3/filename2\n";
       $string .=" Folder4/Folder2/Folder3/filename3\n";
?>

I want to return the next array

<?php
 Array
(
    [Folder1] => Array
        (
            [Folder2] => Array
                (
                    [Folder3] => Array
                        (
                            [0] => filename1
                            [1] => filename2
                        )

                )

        )

    [Folder4] => Array
        (
            [Folder2] => Array
                (
                    [Folder3] => Array
                        (
                            [0] => filename3
                        )

                )

        )

)
?>

What would be the most efficient way to accomplish this?

And for the pleasure of this, let them say that this array will be sent to the other side of the world, and it wants to return to the line. How do we do this?

You could take code snippets from this class , in particular a method _processContentEntry.

Here is a modified version of the method that performs the task:

function stringToArray($path)
{
    $separator = '/';
    $pos = strpos($path, $separator);

    if ($pos === false) {
        return array($path);
    }

    $key = substr($path, 0, $pos);
    $path = substr($path, $pos + 1);

    $result = array(
        $key => stringToArray($path),
    );

    return $result;
}

Conclusion

var_dump(stringToArray('a/b/c/d'));

Will be

array(1) {
  ["a"]=>
  array(1) {
    ["b"]=>
    array(1) {
      ["c"]=>
      array(1) {
        [0]=>
        string(1) "d"
      }
    }
  }
}

I suppose you need :)

UPDATE

, , :

$string = "Folder1/Folder2/Folder3/filename1\n";
$string .= " Folder1/Folder2/Folder3/filename2\n";
$string .= " Folder4/Folder2/Folder3/filename3\n";

// split string into lines
$lines = explode(PHP_EOL, $string);

// trim all entries
$lines = array_map('trim', $lines);

// remove all empty entries
$lines = array_filter($lines);

$output = array();

// process each path
foreach ($lines as $line) {
    // split each line by /
    $struct = stringToArray($line);

    // merge new path into the output array
    $output = array_merge_recursive($output, $struct);
}

print_r($output);

P.S. , json_encode, , , .

$string .="Folder4/Folder2/Folder3/filename3\n";


$string_array_1 = explode("\n", $string);

$array_need = array();

foreach($string_array_1 as $array_values)
{
        if($array_values)
        {
            $folders =  explode("/", $array_values);
            $array_need[$folders[0]][$folders[1]][$folders[2]][] = $folders[3];
        }
    }

print_r($array_need);
