How to flatten folder in php - php

Question

In my server I have folders and sub-directory
I want to call a flatten methode to a directory to move every files at the same level and remove all empty folders
Here is what i've done so far:
public function flattenDir($dir, $destination=null) {
$files = $this->find($dir . '/*');
foreach ($files as $file) {
if(!$destination){
$destination = $dir . '/' . basename($file);
}
if (!$this->isDirectory($file)) {
$this->move($file, $destination);
}else{
$this->flattenDir($file, $destination);
}
}
foreach ($files as $file) {
$localdir = dirname($file);
if ($this->isDirectory($localdir) && $this->isEmptyDirectory($localdir) && ($localdir != $dir)) {
$this->remove($localdir);
}
}
}
public function find($pattern, $flags = 0) {
$files = glob($pattern, $flags);
foreach (glob(dirname($pattern) . '/*', GLOB_ONLYDIR | GLOB_NOSORT) as $dir) {
$files = array_merge($files, $this->find($dir . '/' . basename($pattern), $flags));
}
return $files;
}
This code dont show any error on run, but the resukt is not as expected.
For exemple if I have /folder1/folder2/file I want to have /folder2/file as a result but here the folders still like they where ...

I finally make my code works, I post it here in case it help someone
I simplified it to make it more efficient. By the way this function is part of a filemanager classe I made, so I use function of my own class, but you can simply replace $this->move($file, $destination); by move($file, $destination);
public function flattenDir($dir, $destination = null) {
$files = $this->find($dir . '/*');
foreach ($files as $file) {
$localdir = dirname($file);
if (!$this->isDirectory($file)) {
$destination = $dir . '/' . basename($file);
$this->move($file, $destination);
}
if ($this->isDirectory($localdir) && $this->isEmptyDirectory($localdir) && ($localdir != $dir)) {
$this->remove($localdir);
}
}
}
