PHP循环文件夹并删除旧文件/空文件夹

Question

I have file system shown in picture. My task is to loop from temp folder to last subdirectory and delete files that is older than 30 days and also after that delete empty folders.

I am using "League flysystem/filesystem"

Here is what I got now:

use common\components\helper\FileHelper;
use League\Flysystem\StorageAttributes;

class Tmp
{
    /**
     * @throws \League\Flysystem\FilesystemException
     */
    public static function delete($starting_directory, $time_difference): void
    {
        $filesystem = FileHelper::tempFs();
        $expire = strtotime($time_difference);
        $structure = $filesystem->listContents($starting_directory)
            ->toArray();

        foreach ($structure as $data) {
            if ($data->isDir()) {
                $directory_data = $filesystem->listContents($data['path'])
                    ->toArray();
                if (count($directory_data) === 0) {
                    $filesystem->deleteDirectory($data['path']);
                }
                foreach ($directory_data as $directory) {
                    $filesystem->deleteDirectory($directory['path']);
                    self::delete($directory['path'], $time_difference);
                }
            } else if ($data->isFile() && $data['lastModified'] < $expire) {
                $filesystem->delete($data['path']);
            }
        }
    }
}

File updated. Right now files are deleted after x time and all empty folders except 1st one. First folder after temp deletes after second method init. I guess I am missing a little.

• every directory have no limit for subdirectories.
• Code must accept large amount of files

Answer 1

Well... After two long days of learning and looking how things going I finally made a progress. I made a script for deleting "X time" old files and also empty folders. But still not sure how this script will affect memory with large amount of data.

Here is solution:

use common\components\helper\FileHelper;

class Tmp
{
    /**
     * @throws \League\Flysystem\FilesystemException
     */
    public static function delete($starting_directory, $time_difference): void
    {
        $filesystem = FileHelper::tempFs();
        $expire = strtotime($time_difference);
        $structure = $filesystem->listContents($starting_directory)
            ->toArray();

        foreach ($structure as $data) {
            if ($data->isDir()) {
                self::delete($data['path'], $time_difference);
                $directory_data = $filesystem->listContents($data['path'])
                    ->toArray();
                if (count($directory_data) === 0) {
                    $filesystem->deleteDirectory($data['path']);
                }
            } else if ($data->isFile() && $data['lastModified'] < $expire) {
                $filesystem->delete($data['path']);
            }
        }
    }
}

Maybe someone have opinion about possible memory usage running this script?
