Flysystem is a filesystem abstraction which allows you to easily swap out a local filesystem for a remote one.

# Goals

* Have a generic API for handling common tasks across multiple file storage engines.
* Have consistent output which you can rely on.
* Integrate well with other packages/frameworks.
* Be cacheable.
* Emulate directories in systems that support none, like AwsS3.
* Support third party plugins.
* Make it easy to test your filesystem interactions.
* Support streams for big file handling

# Installation

Through Composer, obviously:

```
composer require league/flysystem
```

You can also use Flysystem without using Composer by registering an autoloader function:

```php
spl_autoload_register(function($class) {
    $prefix = 'League\\Flysystem\\';

    if ( ! substr($class, 0, 17) === $prefix) {
        return;
    }

    $class = substr($class, strlen($prefix));
    $location = __DIR__ . 'path/to/flysystem/src/' . str_replace('\\', '/', $class) . '.php';

    if (is_file($location)) {
        require_once($location);
    }
});
```
