PHPVfs

Description

An implementation of virtual file system and its stream wrapper in PHP.

Requirements

  • PHP >= 7.1

Installation

composer require drupol/phpvfs

Usage

Using the default PHP stream wrapper.

<?php

declare(strict_types = 1);

require_once 'vendor/autoload.php';

use drupol\phpvfs\Exporter\AttributeAscii;
use drupol\phpvfs\Filesystem\Filesystem;
use drupol\phpvfs\Exporter\GvDisplayFilesystem;
use drupol\phpvfs\StreamWrapper\PhpVfs;
use drupol\phpvfs\Node\Directory;
use drupol\launcher\Launcher;

// Create directory container.
$root = Directory::create('/');

// Create a virtual filesystem.
$vfs = new Filesystem($root);

// Register a new PHP streamwrapper (phpvfs://)
PhpVfs::register($vfs);

// Open a file handler for writing.
$file = \fopen('phpvfs://foo.txt', 'w');

// Write something.
\fwrite($file, 'bar');

// Close the file handler.
\fclose($file);

// Create a directory.
$vfs
    ->getCwd()
    ->mkdir('/a/b/c');

// Move the file.
rename('phpvfs://foo.txt', 'phpvfs://a/b/c/bar.txt');

// Get the content of the file.
$test = file_get_contents('phpvfs://a/b/c/bar.txt'); // returns 'bar'

// Export the filesystem into an ascii tree.
echo (new AttributeAscii())->export($vfs->root());

// Export the filesystem into an image and display it.
// In order to display the image, you need the package drupol/launcher
// composer require drupol/launcher
$exporter = new GvDisplayFilesystem();
Launcher::open($exporter->setFormat('svg')->export($root));

Using simple directories structure

<?php

declare(strict_types = 1);

require_once 'vendor/autoload.php';

use drupol\launcher\Launcher;
use drupol\phpvfs\Exporter\GvDisplayFilesystem;
use drupol\phpvfs\Node\Directory;
use drupol\phpvfs\Node\File;

$root = Directory::create('/');

$files = [
    File::create('/a/b/c/d/foo.txt', 'foo'),
    File::create('/a/b/c/d/bar.txt', 'foo'),
    File::create('/a/file_in_a_dir.txt', 'foo'),
    File::create('/a/b/file_in_b_dir.txt', 'foo'),
    File::create('/a/b/c/v/g/file_in_dir.txt', 'foo'),
    File::create('/tmp/tmp.txt', 'foo'),
];

$root->add(...$files);

// Export the filesystem into an image and display it.
// In order to display the image, you need the package drupol/launcher
// composer require drupol/launcher
$exporter = new GvDisplayFilesystem();
Launcher::open($exporter->setFormat('svg')->export($root));

Objects

The current filesystem objects are

  • Filesystem: A filesystem can contains directories and files
  • Directory: A directory can contains directories and files.
  • File: A file cannot contains anything.

Code quality, tests and benchmarks

Every time changes are introduced into the library, Travis CI run the tests and the benchmarks.

The library has tests written with PHPSpec. Feel free to check them out in the spec directory. Run composer phpspec to trigger the tests.

Before each commit some inspections are executed with GrumPHP, run ./vendor/bin/grumphp run to check manually.

PHPBench is used to benchmark the library, to run the benchmarks: composer bench

PHPInfection is used to ensure that your code is properly tested, run composer infection to test your code.

Contributing

Feel free to contribute to this library by sending Github pull requests. I'm quite reactive :-)
