README

A ZIP utility for creating and unziping ZIP files.

Installation

To install this package

$ composer require originphp/zip

Static Methods

The static methods provide a quick way to zip and unzip archives.

Create a ZIP Archive

To create a ZIP archive using a file or directory

Zip::zip(__DIR__ .'/src','/backups/today.zip');

You can also ZIP multiple files or directories

Zip::zip([
    'README.md',
    __DIR__ .'/src'
    ],'/backups/today.zip');

You can also pass any of the following options keys

• password: a password used to encrypt the archive with
• compress: default:true. Set to false to only store the files (without compression)
• encryption: default:aes256. This is the encryption method used when using a password. Supported encryption methods: aes128,aes192,and aes256.

To encrypt files with passwords you need to be using PHP 7.3 or above.

Zip::zip(__DIR__ .'/src','/backups/today.zip',[
    'password'=>'passw0rd'
    ]);

Unzip a ZIP Archive

To unzip a ZIP file

Zip::unzip('/backups/today.zip','/a/folder');

If any of the files are encrypted you provide a password like this

Zip::unzip('/backups/today.zip','/a/folder',[
    'password' => 'passw0rd'
]);

Fluent Interface

The ZIP class also provides a fluent interface for working with ZIP archives.

Create a ZIP Archive

To create a new ZIP and files and directories. When you add a directory it will add all files and sub directories recursively.

$zip = new Zip();
$zip->create('/path/to/file.zip')
    ->add('README.md')
    ->add('src')
    ->save();

Encryption

To encrypt files with passwords you need to be using PHP 7.3 or above.

To encrypt all the files in the archive, call the encrypt method after adding the files, you can optionally supply the encryption method. Supported encryption methods are aes128,aes192 and aes256.

$zip = new Zip();
$zip->create('/path/to/file.zip')
    ->add('README.md')
    ->add('src')
    ->encrypt('passw0rd')
    ->save();

If just want to encrypt certain files

$zip = new Zip();
$zip->create('/path/to/file.zip')
    ->add('README.md')
    ->add('Financials.xlsx',['password' => 'secret'])
    ->save();

Compression

If you just want to store a file in the ZIP archive without compression you can set compress to false.

$zip = new Zip();
$zip->create('/path/to/file.zip')
    ->add('logo.jpg',['compress'=>false])
    ->save();

Unzip a ZIP Archive

To extract files from a ZIP file

$zip = new Zip();
$zip->open('/path/to/file.zip')
    ->extract('/destination/folder')

If the ZIP file has encrypted files

$zip = new Zip();
$zip->open('/path/to/file.zip')
    ->extract('/destination/folder',['password'=>'foo']);

You can also extract selected files

$zip = new Zip();
$zip->open('/path/to/file.zip')
    ->extract('/destination/folder',[
        'files'=>[
            'README.md',
            'LICENSE.md'
        ]
    ]);

Listing contents

To list contents of a ZIP file

$zip = new Zip();
$list = $zip->open('/path/to/file.zip')
            ->list();

This will output like this

Array
(
    [0] => Origin\Zip\FileObject Object
        (
            [name] => README.md
            [size] => 666
            [timestamp] => 1576656596
            [compressedSize] => 371
            [encrypted] => 1
        )
)

You can also just list files from within a folder of the ZIP file

$zip = new Zip();
$testFiles = $zip->open('/path/to/file.zip')
                 ->list('tests');

Getting contents of a file

To get the contents of a file

$zip = new Zip();
$contents = $zip->open('/path/to/file.zip')
                 ->get('README.md');

Renaming

To rename a file in a ZIP archive

$zip = new Zip();
$zip->open('/path/to/file.zip')
    ->rename('foo.txt','bar.txt');

Deleting Files

To delete a file from a ZIP archive

$zip = new Zip();
$zip->open('/path/to/file.zip')
    ->delete('tests/ControllerTest.php');
