Flysystem, introduced in Laravel 5.0, is a file system abstraction layer that allows local file systems and cloud-based storage services provided by Amazon S3 and Rackspace Cloud to be used transparently and in the same way.
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');
