PHP flatten a directory - php

Question

I'm using flysystem to work with my files.
I don't see an easy way to flatten a directory so I used this
public function flattenDir($dir, $destination = null) {
$files = find($dir . '/*');
foreach ($files as $file) {
$localdir = dirname($file);
if (!isDirectory($file)) {
$destination = $dir . '/' . basename($file);
move($file, $destination);
}
if (isDirectory($localdir) && isEmptyDirectory($localdir) && ($localdir != $dir)) {
remove($localdir);
}
}
}
Is there an easier way by using flysystem?

I finally used that. It also manage a few things that I needed
I'm using flysystem mount manager but this script could be easily adapted to work with the default flysystem instance.
$elements should be the result of manager->listContents('local://my_dir_to_flatten');
And $root is a string my_dir_to_flatten in my case.
public function flatten($elements , $root) {
$files = array();
$directories = array();
//Make difference between files and directories
foreach ($elements as $element) {
if( $element['type'] == 'file' ) {
array_push($files, $element);
} else {
array_push($directories, $element);
}
}
//Manage files
foreach ($files as $file) {
//Dont move file already in root
if($file['dirname'] != $root) {
//Check if filename already used in root directory
if ( $this->manager->has('local://'.$root . '/' . $file['basename']) ) {
//Manage if file don't have extension
if( isset( $file['extension']) ) {
$file['basename'] = $file['filename'] . uniqid() . '.' . $file['extension'];
} else {
$file['basename'] = $file['filename'] . uniqid();
}
}
//Move the file
$this->manager->move('local://' . $file['path'] , 'local_process://' . $root . '/' . $file['basename']);
}
}
//Delete folders
foreach ($not_files as $file) {
$this->manager->deleteDir( 'local://' . $file['path'] );
}
}
