I want o sort a multidimensional array (which I don't know the length) and keep the index strings. The data of this multidimensional array is from a directory which can have unlimited folders & files.
I have successfully grabbed the folder structure into an array using this List all the files and folders in a Directory with PHP recursive function and I can sort the array with a recursive function like this https://stackoverflow.com/a/4501406/3355243.
Problem
When sorting, all the array indexs are replaced with numbers. I'd like to keep the array index as strings because it holds the folder name.
Input
Folder A => Array
(
file.php,
file1.php,
Folder B => Array
(
file.php,
file1.php,
Folder A => Array
(
file.php,
file1.php,
)
something.php
),
something.php
),
Folder B => Array
(
other.php,
other2.php
),
Folder C => Array
(
Folder A => Array
(
a.php,
b.php
),
something.php
)
Expected output
Folder A => Array
(
file.php,
file1.php,
something.php,
Folder B => Array
(
file.php,
file1.php,
something.php,
Folder A => Array
(
file.php,
file1.php,
)
),
),
Folder B => Array
(
other.php,
other2.php
),
Folder C => Array
(
something.php
Folder A => Array
(
a.php,
b.php
),
)
Current output
0 => Array
(
file.php,
file1.php,
something.php,
0 => Array
(
file.php,
file1.php,
something.php,
0 => Array
(
file.php,
file1.php,
)
),
),
1 => Array
(
other.php,
other2.php
),
2 => Array
(
something.php
0 => Array
(
a.php,
b.php
),
)
Final goal
To show the array / folder structure into a select box with Groups & Options.
