README

ZippyExt (aka ZippyExtended) is a library extended over Zippy providing the strategy and adapter for using 7-Zip, including password support.

Requirements

• PHP >= 8.1
• 7-Zip (7za or 7z in PATH) — required only for 7zip adapter

PHP Compatibility

ZippyExt	PHP
1.x	8.1–8.3
0.x	7.0+

Installation

The only supported installation method is via Composer. Run the following command to require ZippyExt in your project:

composer require victor78/zippy-ext

Adapters

ZippyExt currently supports the following drivers and file formats:

• zip
  • .zip
• PHP zip extension
  • .zip
• GNU tar
  • .tar
  • .tar.gz
  • .tar.bz2
• BSD tar
  • .tar
  • .tar.gz
  • .tar.bz2
• 7zip
  • .zip (with optional AES-256 password encryption)

Getting started

All the following code samples assume that ZippyExt is loaded and available as $zippy. You need the following code (or variation of) to load ZippyExt:

<?php

use Victor78\ZippyExt\Zippy;

// Require Composer's autoloader
require __DIR__ . '/vendor/autoload.php';

// Load Zippy
$zippy = Zippy::load();

List an archive's contents:

// Open an archive
$archive = $zippy->open('build.tar');

// Iterate through members
foreach ($archive as $member) {
    echo "Archive contains $member" . PHP_EOL;
}

Extract an archive to a specific directory:

// Open an archive
$archive = $zippy->open('build.tar');

// Extract archive contents to `/tmp`
$archive->extract('/tmp');

Create a new archive

// Creates an archive.zip that contains a directory "folder" that contains
// files contained in "/path/to/directory" recursively
$archive = $zippy->create('archive.zip', array(
    'folder' => '/path/to/directory'
), true);

Use 7zip

If you need to use 7zip archiving to create a zip archive, use the fourth parameter:

// Creates an archive.zip using the 7zip engine
$archive = $zippy->create('archive.zip', $files, true, '7zip');

To create an AES-256 encrypted archive, pass the password as the fifth parameter:

// Creates an archive.zip with AES-256 encryption
$archive = $zippy->create('archive.zip', $files, true, '7zip', 'your_password');

To open and extract a password-protected 7zip archive:

// Open archive with password
$archive = $zippy->open('archive.zip', '7zip', 'your_password');
$archive->extract('folder_for_extracted');

Known Limitations

• Password protection is only supported with the 7zip adapter. Standard zip and tar adapters ignore the password parameter.
• extractMembers() is not supported for the 7zip adapter (use extract() instead).
• .zip is ambiguous: by default, open('file.zip') may resolve to standard zip strategy. If you need 7zip-specific behavior (including password flow), pass type explicitly: open('file.zip', '7zip', 'your_password').
