develop

Filesystem abstraction layer, the goal is to provide a model where you design how you put your files into directories without worrying where it will be persisted.

Installation

composer install innmind/filesystem

Usage

The whole model is structures around files, directories, streams and adapters. File, Directory and Stream are immutable objects.

Example:

use Innmind\Filesystem\{
    File\File,
    Directory\Directory,
    Name,
    Adapter\Filesystem,
};
use Innmind\Url\Path;
use Innmind\Stream\Readable\Stream;

$directory = Directory::named('uploads')->add(
    File::named(
        $_FILES['my_upload']['name'],
        Stream::open($_FILES['my_upload']['tmp_name'])
    )
);
$adapter = new Filesystem(Path::of('/var/www/web'));
$adapter->add($directory);

This example show you how you can create a new directory uploads in the folder /var/www/web of your filesystem and create the uploaded file into it.

Note: For performance reasons the filesystem adapter only persist to disk the files that have changed (achievable via the immutable nature of file objects).

All adapters implements Adapter, so you can easily replace them; especially for unit tests, that's why the library comes with an InMemory adapter that only keeps the files into memory so you won't mess up your file system.

By default when you call add or remove on an adapter the changes are directly applied, but you can change this behaviour by wrapping your adapter in another one implementing LazyAdapter (such as Lazy).

Example:

use Innmind\Filesystem\Adapter\LazyAdapter;

$directory = /*....*/ ;
$adapter = new Lazy(new Filesystem(Path::of('/var/www/web')));
$adapter->add($directory); // nothing is written to disk
$adapter->persist(); // every new files are persisted, and removals occur at this time as well
