README

Distill extracts files from compressed archives.

Features:

• Extract files from ar, bz2, cab, chm, cpio, deb, dmg, epub, gz, phar, rar, shar, tar, tar.bz2, tar.gz, tar.xz, wim, 7z, xz, Z and zip archives.
• Different decompression methods under the hood: PHP extensions, command line binaries, third-party libraries and even fallback methods in plain PHP.
• Strategy to choose the right file in case there are more than one available format. Strategies can be based on minimizing bandwidth or optimizing decompression speed.

Installation

The recommended way to install Distill is through Composer. Require the raulfraile/distill package into your composer.json file:

{
    "require": {
        "raulfraile/distill": "@stable"
    }
}

Protip: you should browse the raulfraile/distill page to choose a stable version to use, avoid the @stable meta constraint.

Otherwise, install the library and setup the autoloader yourself.

Example

use Distill\Distill;

$distill = new Distill();
$distill->extract(__DIR__ . '/../tests/files/file_ok.zip', __DIR__ . '/extract');

Formats

Strategies

Distill allows to choose one format in case there are many available. For example, it can be useful for installers that want to reduce the bandwidth usage trying to choose compression formats with higher compression ratio and available in the client machine.

The library provides three strategies (more can be added):

• Minimum size (default): Choose files with higher compression ratio.
• Uncompression speed: Choose files which are faster to uncompress.
• Random: Gets a random file which can be uncompressed by the system.

use Distill\Distill;

$distill = new Distill();

$preferredFile = $distill
    ->getChooser()
    ->setStrategy(new \Distill\Strategy\MinimumSize())
    ->addFile('http://get.symfony.com/Symfony_Standard_Vendors_2.5.3.zip')
    ->addFile('http://get.symfony.com/Symfony_Standard_Vendors_2.5.3.tgz')
    ->getPreferredFile();

echo $preferredFile; // http://get.symfony.com/Symfony_Standard_Vendors_2.5.3.tgz

use Distill\Distill;

$distill = new Distill();

$preferredFile = $distill
    ->getChooser()
    ->setStrategy(new \Distill\Strategy\UncompressionSpeed())
    ->addFile('test.phar')
    ->addFile('test.zip')
    ->getPreferredFile();

echo $preferredFile; // test.zip

Command line tool

If you are looking for a command line tool to extract compressed files check out distill-cli, which uses this library:

$ distill-cli extract archive.tar.gz path/
