README

PHP package to handle archives (.zip, .rar, .tar, .7z) or .pdf with hybrid solution (native/p7zip), designed to works with eBooks (.epub, .cbz, .cbr, .cb7, .cbt).

Supports Linux, macOS and Windows.

Warning

For some formats (.rar and .7z) rar PHP extension or p7zip binary could be necessary, see Requirements.

Requirements

PHP version >= 8.1
PHP extensions:
- zip (native, optional) for .ZIP, .EPUB, .CBZ archives
- fileinfo (native, optional) for better file detection
- rar (optional) for .RAR, .CBR archives
- imagick (optional) for .PDF
- bz2 (optional) for .BZ2 archives

Type	Supported	Requirement	Uses
`.zip`, `.epub`, `.cbz`	✅	N/A	Uses `zip` extension
`.tar`, `.tar.gz`, `.cbt`	✅	N/A	Uses `phar` extension
`.rar`, `.cbr`	✅	`rar` PHP extension or `p7zip` binary	PHP `rar` or `p7zip`
`.7z`, `.cb7`	✅	`p7zip` binary	`p7zip` binary
`.pdf`	✅	Optional (for extraction) `imagick` PHP extension	`smalot/pdfparser`

Note

Here you can read some installation guides for dependencies

Warning

On macOS, for .rar extract, you have to install rar binary to extract files, p7zip not support .rar extraction.
On Windows, for .pdf extract, imagick PHP extension have to work but my tests failed on this feature. So to extract PDF pages I advice to use WSL.

If you want more information, you can read section About.

Installation

You can install the package via composer:

composer require kiwilan/php-archive

Usage

Read and extract

With archive file (.zip, .rar, .tar, .7z, epub, cbz, cbr, cb7, cbt, tar.gz, .pdf).

$archive = Archive::read('path/to/archive.zip');

$files = $archive->getFiles(); // ArchiveItem[]
$count = $archive->getCount(); // int of files count

$images = $archive->filter('jpeg'); // ArchiveItem[] with `jpeg` in their path
$metadataXml = $archive->find('metadata.xml'); // First ArchiveItem with `metadata.xml` in their path
$content = $archive->getContents($metadataXml); // `metadata.xml` file content

$paths = $archive->extract('/path/to/directory', [$metadataXml]); // string[] of extracted files paths
$paths = $archive->extractAll('/path/to/directory'); // string[] of extracted files paths

PDF files works with same API than archives but with some differences.

$archive = Archive::read('path/to/file.pdf');

$pdf = $archive->getPdf(); // Metadata of PDF

$content = $archive->getContents($archive->getFirst()); // PDF page as image
$text = $archive->getText($archive->getFirst()); // PDF page as text

Stat

From stat PHP function: https://www.php.net/manual/en/function.stat.php

Gives information about a file

$archive = Archive::read('path/to/file.zip');
$stat = $archive->stat();

$stat->getPath(); // Path of file
$stat->getDeviceNumber(); // Device number
$stat->getInodeNumber(); // Inode number
$stat->getInodeProtectionMode(); // Inode protection mode
$stat->getNumberOfLinks(); // Number of links
$stat->getUserId(); // User ID
$stat->getGroupId(); // Group ID
$stat->getDeviceType(); // Device type
$stat->getSize(); // Size of file
$stat->getLastAccessAt(); // Last access time
$stat->getCreatedAt(); // Creation time
$stat->getModifiedAt(); // Last modification time
$stat->getBlockSize(); // Block size
$stat->getNumberOfBlocks(); // Number of blocks
$stat->getStatus(); // Status

Create

You can create archive with method Archive::make method.

Works only with .zip archives.

$archive = Archive::make('path/to/archive.zip');
$files = [
    'path/to/file/in/archive-file1.txt' => 'path/to/real-file1.txt',
    'path/to/file/in/archive-file2.txt' => 'path/to/real-file2.txt',
    'path/to/file/in/archive-file3.txt' => 'path/to/real-file3.txt',
];

foreach ($files as $pathInArchive => $pathToRealFile) {
    $archive->addFile($pathInArchive, $pathToRealFile);
}
$archive->addFromString('test.txt', 'Hello World!');
$archive->addDirectory('./directory', 'path/to/directory');
$archive->save();

Edit

You can edit archive with same method Archive::make method.

$archive = Archive::make('path/to/archive.zip');
$archive->addFromString('test.txt', 'Hello World!');
$archive->save();

Testing

composer test

This package was inspired by this excellent post on StackOverflow which make state of the art of PHP archive handling. The package Gemorroj/Archive7z was also a good source of inspiration cause it's the only package that handle .7z archives with wrapper of p7zip fork binary. But I would to handle all main archives formats with native PHP solution it possible, and use p7zip binary only if native solution is not available.

State of the art of PHP archive handling:

.zip with ZipArchive
.tar with PharData
.rar with RarArchive if rar extension is installed
.7z can't be handled with native PHP solution

Type	Is native	Solution
ZIP	✅	Native
TAR	✅	Native
RAR	❌	`rar` or `p7zip` binary
7ZIP	❌	`p7zip` binary
PDF	❌	`smalot/pdfparser`

Why not full wrapper of `p7zip` binary?

This solution is used by Gemorroj/Archive7z, and it works well. But another problem is the usage of the p7zip fork which is not the official p7zip binary and can be difficult to install on some systems.

PHP can handle natively some archive formats, but not all. So I choose to use native PHP solution when it's possible, and use p7zip binary with official version when it's not possible.

Case of `rar`

The rar PHP extension is not installed by default on PHP, developers have to install it manually. This extension is not actively maintained and users could have some compilation problems. To install it with PHP 8.1 or 8.2, it's necessary to compile manually the extension, you could read this guide if you want to install it (for PHP 8.2, you will have a warning message but it's not a problem, the extension will work).

But rar PHP extension is a problem because it's not sure to have a compatibility with future PHP versions. So I choose to handle rar archives with p7zip binary if rar PHP extension is not installed.

Gemorroj/Archive7z: handle many archives with p7zip-project/p7zip binary
splitbrain/php-archive: native PHP solution to handle .zip and .tar archives
maennchen/ZipStream-PHP: A fast and simple streaming zip file downloader for PHP. Using this library will save you from having to write the Zip to disk.
