Filesystem / Cloud Storage
Introduction
Laravel provides a wonderful filesystem abstraction thanks to the Flysystem PHP package by Frank de Jonge. The Laravel Flysystem integration provides simple to use drivers for working with local filesystems, Amazon S3, and Rackspace Cloud Storage. Even better, it's amazingly simple to switch between these storage options as the API remains the same for each system!
Configuration
The filesystem configuration file is located at config/filesystems.php
. Within this file you may configure all of your "disks". Each disk represents a particular storage driver and storage location. Example configurations for each supported driver is included in the configuration file. So, simply modify the configuration to reflect your storage preferences and credentials!
Before using the S3 or Rackspace drivers, you will need to install the appropriate package via Composer:
- Amazon S3:
league/flysystem-aws-s3-v2 ~1.0
- Rackspace:
league/flysystem-rackspace ~1.0
Of course, you may configure as many disks as you like, and may even have multiple disks that use the same driver.
When using the local
driver, note that all file operations are relative to the root
directory defined in your configuration file. By default, this value is set to the storage/app
directory. Therefore, the following method would store a file in storage/app/file.txt
:
Storage::disk('local')->put('file.txt', 'Contents');
Basic Usage
The Storage
facade may be used to interact with any of your configured disks. Alternatively, you may type-hint the Illuminate\Contracts\Filesystem\Factory
contract on any class that is resolved via the Laravel service container.
Retrieving A Particular Disk
$disk = Storage::disk('s3');
$disk = Storage::disk('local');
Determining If A File Exists
$exists = Storage::disk('s3')->exists('file.jpg');
Calling Methods On The Default Disk
if (Storage::exists('file.jpg'))
{
//
}
Retrieving A File's Contents
$contents = Storage::get('file.jpg');
Setting A File's Contents
Storage::put('file.jpg', $contents);
Prepend To A File
Storage::prepend('file.log', 'Prepended Text');
Append To A File
Storage::append('file.log', 'Appended Text');
Delete A File
Storage::delete('file.jpg');
Storage::delete(['file1.jpg', 'file2.jpg']);
Copy A File To A New Location
Storage::copy('old/file1.jpg', 'new/file1.jpg');
Move A File To A New Location
Storage::move('old/file1.jpg', 'new/file1.jpg');
Get File Size
$size = Storage::size('file1.jpg');
Get The Last Modification Time (UNIX)
$time = Storage::lastModified('file1.jpg');
Get All Files Within A Directory
$files = Storage::files($directory);
// Recursive...
$files = Storage::allFiles($directory);
Get All Directories Within A Directory
$directories = Storage::directories($directory);
// Recursive...
$directories = Storage::allDirectories($directory);
Create A Directory
Storage::makeDirectory($directory);
Delete A Directory
Storage::deleteDirectory($directory);
Custom Filesystems
Laravel's Flysystem integration provides drivers for several "drivers" out of the box; however, Flysystem is not limited to these and has adapters for many other storage systems. You can create a custom driver if you want to use one of these additional adapters in your Laravel application. Don't worry, it's not too hard!
In order to set up the custom filesystem you will need to create a service provider such as DropboxFilesystemServiceProvider
. In the provider's boot
method, you can inject an instance of the Illuminate\Contracts\Filesystem\Factory
contract and call the extend
method of the injected instance. Alternatively, you may use the Disk
facade's extend
method.
The first argument of the extend
method is the name of the driver and the second is a Closure that receives the $app
and $config
variables. The resolver Closure must return an instance of League\Flysystem\Filesystem
.
Note: The $config variable will already contain the values defined in
config/filesystems.php
for the specified disk.
Dropbox Example
<?php namespace App\Providers;
use Storage;
use League\Flysystem\Filesystem;
use Dropbox\Client as DropboxClient;
use League\Flysystem\Dropbox\DropboxAdapter;
use Illuminate\Support\ServiceProvider;
class DropboxFilesystemServiceProvider extends ServiceProvider {
public function boot()
{
Storage::extend('dropbox', function($app, $config)
{
$client = new DropboxClient($config['accessToken'], $config['clientIdentifier']);
return new Filesystem(new DropboxAdapter($client));
});
}
public function register()
{
//
}
}
