The library supports `ZIP64`, `zipalign`, `Traditional PKWARE Encryption` and `WinZIP AES Encryption`.
The library does not require extension `php-xml` and class `ZipArchive`.
ZIP64 extensions are automatically and transparently activated when reading or writing ZIP files of more than 4 GB size.
The library does not require extension `php-zip` and class `ZipArchive`.
Requirements
------------
- `PHP` >= 5.4 (64 bit)
- Php-extension `mbstring`
- PHP-extension `mbstring`
- Optional php-extension `bzip2` for BZIP2 compression.
- Optional php-extension `openssl` or `mcrypt` for `WinZip Aes Encryption` support.
