ZipStream-PHP

Unstable Branch

The main branch is not stable. Please see the releases for a stable version.

Overview

A fast and simple streaming zip file downloader for PHP. Using this library will save you from having to write the Zip to disk. You can directly send it to the user, which is much faster. It can work with S3 buckets or any PSR7 Stream.

Please see the LICENSE file for licensing and warranty information.

Upgrade to version 3.0.0

General

• Minimum PHP Version: 8.1
• Only 64bit Architecture is supported.
• The class ZipStream\Option\Method has been replaced with the enum ZipStream\CompressionMethod.
• Most clases have been flagged as @internal and should not be used from the outside. If you're using internal resources to extend this library, please open an issue so that a clean interface can be added & published. The externally available classes & enums are:
  • ZipStream\CompressionMethod
  • ZipStream\Exception*
  • ZipStream\ZipStream

Archive Options

• The class ZipStream\Option\Archive has been replaced in favor of named arguments in the ZipStream\ZipStream constuctor.
• The archive options largeFileSize & largeFileMethod has been removed. If you want different compressionMethods based on the file size, you'll have to implement this yourself.
• The archive option httpHeaderCallback changed the type from callable to Closure.
• The archive option zeroHeader has been replaced with the option defaultEnableZeroHeader and can be overridden for every file. Its default value changed from false to true.
• The archive option statFiles was removed since the library no longer checks filesizes this way.
• The archive option deflateLevel has been replaced with the option defaultDeflateLevel and can be overridden for every file.
• The first argument (name) of the ZipStream\ZipStream constuctor has been replaced with the named argument outputName.
• Headers are now also sent if the outputName is empty. If you do not want to automatically send http headers, set sendHttpHeaders to false.

File Options

• The class ZipStream\Option\File has been replaced in favor of named arguments in the ZipStream\ZipStream->addFile* functions.
• The file option method has been renamed to compressionMethod.
• The file option time has been renamed to lastModificationDateTime.
• The file option size has been renamed to maxSize.
