Replace Filesystem, FTP with FlySystem in order to support more filesystems

Commencez par localiser les modules FileSystem et FTP personnalisés mentionnés dans l’issue, puis comparez leurs APIs avec l’API FlySystem liée dans la description. Recensez le comportement des modules existants et les opérations prises en charge avant de décider de la portée de la migration ; le travail est considéré comme terminé lorsque le remplacement prend en charge les opérations requises sans perdre les fonctionnalités actuelles et que les tests des modules passent.

"FlySystem is a filesystem abstraction which allows you to easily swap out a local filesystem for a remote one. Reducing technical debt and chance of vendor lock-in."

It could replace the custom FileSystem and FTP modules and offer support for many more filesystems. Here is a list of what's available today :

• Local
• Azure
• AWS S3 V2
• AWS S3 V3
• Copy.com
• Dropbox
• FTP / SFTP
• GridFS
• Memory
• Rackspace
• WebDAV
• PHPCR
• ZipArchive

The API

http://flysystem.thephpleague.com/api/

Write Files

$filesystem->write('path/to/file.txt', 'contents');

Update Files

$filesystem->update('path/to/file.txt', 'new contents');

Write or Update Files

$filesystem->put('path/to/file.txt', 'contents');

Read Files

$contents = $filesystem->read('path/to/file.txt');

Check if a file exists

$exists = $filesystem->has('path/to/file.txt');

Delete Files

$filesystem->delete('path/to/file.txt');

Read and Delete

$contents = $filesystem->readAndDelete('path/to/file.txt');

Rename Files

$filesystem->rename('filename.txt', 'newname.txt');

Copy Files

$filesystem->copy('filename.txt', 'duplicate.txt');

Get Mimetypes

$mimetype = $filesystem->getMimetype('path/to/file.txt');

Get Timestamps

$timestamp = $filesystem->getTimestamp('path/to/file.txt');

Get File Sizes

$size = $filesystem->getSize('path/to/file.txt');

Create Directories

$filesystem->createDir('path/to/nested/directory');

Directories are also made implicitly when writing to a deeper path

$filesystem->write('path/to/file.txt', 'contents');

Delete Directories

$filesystem->deleteDir('path/to/directory');
