InMemory
This adapter is useful in test environments where you don't want to depend on external filesystems.
First, you will need to install the adapter:
composer require gaufrette/in-memory-adapter
Example
InMemory
adapter only takes an array of available files as argument.
<?php
use Gaufrette\Adapter\InMemory;
use Gaufrette\Filesystem;
$adapter = new InMemory(array('my/file' => 'its content'));
$filesystem = new Filesystem($adapter);
