## What it is
A PHP library for streaming ZIP files directly to clients without writing to disk. It supports PSR-7 streams, S3 buckets, and callback output for efficient on-the-fly ZIP generation.

## Use cases
- stream zip downloads in php without temp files
- send large zip files directly to browser
- build zip on the fly from s3 bucket
- stream zip archive to psr7 stream
- generate downloadable zip of user uploads
- compress files to s3 compatible storage

## When to choose
- you need to serve ZIP downloads from PHP without disk I/O
- files to zip live in S3 or PSR-7 streams
- memory or disk usage must stay low for large archives

## When to avoid
- you need to create ZIP files on disk for later use
- your project is not PHP
- you need advanced archive formats like tar or 7z

## Facets
- artifact type: library
- maturity: stable
- function: compression, file-system, http-server
- domain: files, web-development, backend
- platform: php
- tags: zip, streaming, psr7, s3, composer, web-server
