Gaufrette is a PHP5 library that provides a filesystem abstraction layer.
This project is under intensive development. Everything can change at any time!
Why use Gaufrette?
Imagine you have to manage a lot of medias in a PHP project. Lets see how to take this situation in your advantage using Gaufrette.
The filesystem abstraction layer permits you to develop your application without the need to know were all those medias will be stored and how.
Another advantage of this is the possibility to update the files location without any impact on the code apart from the definition of your filesystem. In exemple, if your project grows up very fast and if your server reaches its limits, you can easily move your medias in an Amazon S3 server or any other solution.
Setup your filesystem
<?php use Gaufrette\Filesystem\Filesystem; use Gaufrette\Filesystem\Adapter\Local as LocalAdapter; $adapter = new LocalAdapter('/var/media'); $filesystem = new Filesystem($adapter)
Use the filesystem
<?php // ... setup your filesystem $content = $filesystem->read('myFile'); $content = 'Hello I am the new content'; $filesystem->write('myFile', $content);
Use file objects
Gaufrette also provide a File class that is a representation of files in a filesystem
<?php $file = new File('newFile', $filesystem); $file->setContent('Hello World'); echo $file->getContent(); // Hello World
Cache a slow filesystem
If you have to deal with a slow filesystem, it is out of quetion to use it directly. So, you need a cache! Happily, Gaufrette offers a cache system ready for use. It consist of an adapter itself composed of two adapters:
* The *source* adapter that should be cached * The *cache* adapter that is used to cache
Here is an exemple of how to cache an ftp filesystem:
<?php use Gaufrette\Filesystem\Filesystem; use Gaufrette\Filesystem\Adapter\Ftp as FtpAdapter; use Gaufrette\Filesystem\Adapter\Local as LocalAdapter; // create an ftp adapter instance as $ftp and a local one as $local $cachedFtp = new CacheAdapter($ftp, $local, 10); $filesystem = new Filestystem($cachedFtp);
The third parameter of the cache adapter is the time to live of the cache.
Using Gaufrette in a Symfony2 project
As you can see, Gaufrette provides an elegant way to declare your filesystems. If you want to use them in a Symfony2 project, you can simply add them as services of your dependency injection container.
Running the Tests
The tests use PHPUnit.
Setup the vendor libraries
As some filesystem adapters use vendor libraries, you should install the vendors:
It will avoid skip a lot of tests.
Launch the Test Suite
In the Gaufrette root directory:
$ phpunit -c .
