SevenZip 🔧

A PHP package to compress and decompress files using 7zip CLI.

GitHub Actions Workflow Status

Installation

Install the package via Composer:

composer require verseles/sevenzip
️Star the project to help us reach move devs!️

Usage

Compression

To compress a file or directory:

$sevenZip = new SevenZip();
$sevenZip->format('7z')
         ->source('/path/to/source/file/or/directory')
         ->target('/path/to/archive.7z')
         ->compress();

Compression Options

  • Format: You can set the compression format using the format() method. Well known formats include 7z, zip, tar, lz4, lz5, bzip2, and zstd. Your OS needs to support the selected format.
  • Compression Level: You can adjust the compression level using the faster(), slower(), mx(), and ultra() methods.
  • Custom Flags: You can add custom compression flags using the addFlag() method.
  • Progress Callback: You can set a progress callback using the progress() method to monitor the compression progress.
  • Tar Before: You can enable option to create a tar archive before compressing using the tarBefore() method. This is useful for preserving file permissions and attributes.

Warning

The format support depends on your system, architecture, etc. You can always use format() method to set your custom format.

Any set format() which starts with tar. will automatically enable tarBefore(). To disable add ->forceTarBefore(false)

Extraction

To extract an archive:

$sevenZip = new SevenZip();
$sevenZip->source('/path/to/archive.7z')
         ->target('/path/to/extract/directory')
         ->extract();

If the extracted file is a single tar archive, it will be extracted and the tar file deleted. To avoid this behavior, add ->autoUntar(false)

Encryption

You can encrypt the compressed archive using a password:

$sevenZip = new SevenZip();
$sevenZip->source('/path/to/source/file/or/directory')
         ->target('/path/to/encrypted_archive.7z')
         ->encrypt('your_password')
         ->compress();

By default, the file names are also encrypted (not possible in zip format). If you want to disable file name encryption, you can use the notEncryptNames() method:

$sevenZip->notEncryptNames();

For ZIP archives, you can specify the encryption method using the setZipEncryptionMethod() method. Available options are 'ZipCrypto' (not secure), ' AES128', 'AES192', or 'AES256'. The default is 'AES256'.

$sevenZip->setZipEncryptionMethod('AES256');

Decryption

To decrypt an encrypted archive during extraction:

$sevenZip = new SevenZip();
$sevenZip->source('/path/to/encrypted_archive.7z')
         ->target('/path/to/extract/directory')
         ->decrypt('your_password')
         ->extract();

Including and Excluding Files

SevenZip allows you to include or exclude specific files when compressing or extracting archives.

Including Files

To include specific files in the archive, use the include method:

$sevenZip->include('*.avg')->compress();

Excluding Files

To exclude specific files from the archive, use the exclude method:

$sevenZip->exclude(['*.md', '*.pdf'])->compress();

Note that you can use both include and exclude methods together to fine-tune the files included in the archive.

You can pass a single file pattern, an array of file patterns or the path to a txt file with a list of patterns inside to the exclude and include methods.

Checking format support

You can check if a specific format or multiple formats are supported by the current 7-Zip installation using the checkSupport method:

$sevenZip = new SevenZip();

// Check if a single format is supported
if ($sevenZip->checkSupport('zip')) {
    echo "ZIP format is supported.";
} else {
    echo "ZIP format is not supported.";
}

// Check if multiple formats are supported
if ($sevenZip->checkSupport(['zip', 'tar', '7z'])) {
    echo "ZIP, TAR, and 7Z formats are supported.";
} else {
    echo "One or more formats are not supported.";
}

TODO / WIP

  • Full support for add flags (7z switches)
  • Add custom support for gz, xz, etc. by using tar flags
  • Use tar to keep original file permissions and other attributes
  • Auto untar on extraction
  • Filter files by patterns
  • Encrypt and decrypt
  • Test files using 7z test command
  • Detect supported formats by the OS
  • Add built-in binaries for mac and linux
  • Use docker for PHPUnit tests not needed with built-in binaries
  • Use native zstd, brotli, and others as fallback for these formats
