### <a name="Features"></a> Features
- Opening and unzipping zip files.
- Creating ZIP-archives.
- Modifying ZIP archives.
- Pure php (not require extension `php-zip` and class `\ZipArchive`).
- It supports saving the archive to a file, outputting the archive to the browser, or outputting it as a string without saving it to a file.
- Archival comments and comments of individual entry are supported.
- Get information about each entry in the archive.
- Only the following compression methods are supported:
+ No compressed (Stored).
+ Deflate compression.
+ BZIP2 compression with the extension `php-bz2`.
- Support for `ZIP64` (file size is more than 4 GB or the number of entries in the archive is more than 65535).
- Built-in support for aligning the archive to optimize Android packages (APK) [`zipalign`](https://developer.android.com/studio/command-line/zipalign.html).
- Working with passwords for PHP 5.5
> **Attention!**
>
> For 32-bit systems, the `Traditional PKWARE Encryption (ZipCrypto)` encryption method is not currently supported.
> Use the encryption method `WinZIP AES Encryption`, whenever possible.
+ Set the password to read the archive for all entries or only for some.
+ Change the password for the archive, including for individual entries.
+ Delete the archive password for all or individual entries.
+ Set the password and/or the encryption method, both for all, and for individual entries in the archive.
+ Set different passwords and encryption methods for different entries.
+ Delete the password for all or some entries.
+ Support `Traditional PKWARE Encryption (ZipCrypto)` and `WinZIP AES Encryption` encryption methods.
+ Set the encryption method for all or individual entries in the archive.
### <a name="Requirements"></a> Requirements
- `PHP` >= 5.5 (preferably 64-bit).
- Optional php-extension `bzip2` for BZIP2 compression.
- Optional php-extension `openssl` or `mcrypt` for `WinZip Aes Encryption` support.
### <a name="Installation"></a> Installation
`composer require nelexa/zip`
Latest stable version: [![Latest Stable Version](https://poser.pugx.org/nelexa/zip/v/stable)](https://packagist.org/packages/nelexa/zip)
### <a name="Examples"></a> Examples
```php
// create new archive
$zipFile = new \PhpZip\ZipFile();
try{
$zipFile
->addFromString('zip/entry/filename', 'Is file content') // add an entry from the string
->addFile('/path/to/file', 'data/tofile') // add an entry from the file
->addDir(__DIR__, 'to/path/') // add files from the directory
->saveAsFile($outputFilename) // save the archive to a file
->close(); // close archive
// open archive, extract, add files, set password and output to browser.
$zipFile
->openFile($outputFilename) // open archive from file
->extractTo($outputDirExtract) // extract files to the specified directory
->deleteFromRegex('~^\.~') // delete all hidden (Unix) files
->addFromString('dir/file.txt', 'Test file') // add a new entry from the string
->setPassword('password') // set password for all entries
->outputAsAttachment('library.jar'); // output to the browser without saving to a file
}
catch(\PhpZip\Exception\ZipException $e){
// handle exception
}
finally{
$zipFile->close();
}
```
