    Read and write ZIP archives without `libzip` or `ZipArchive`. Stored entries are pure PHP; Deflate entries use PHP's `zlib` functions. Entries stream one at a time, while ZIP metadata such as the central directory is still held in memory.

Why this exists
---------------

[](#why-this-exists)

Common PHP ZIP workflows rely on the `ZipArchive` extension or shelling out to `zip`. Those are awkward in hosts without libzip, WebAssembly builds, and code paths that need to stream archive data through toolkit byte streams.

The Zip component reads and writes Stored and Deflate archives without `ZipArchive`. The decoder is pull-based for entry bodies, but `ZipFilesystem` indexes the central directory in memory and currently rejects archives whose central directory exceeds 2 MB. The encoder accepts any `ByteWriteStream` as a sink and writes one entry at a time.

Read a file out of a ZIP
------------------------

[](#read-a-file-out-of-a-zip)

`ZipFilesystem` implements this toolkit's `Filesystem` interface, so once you wrap the byte reader you can call `get_contents()`, `ls()`, and `is_dir()` just like the other read backends.

**Try this:** after *Run*, add a second `append_file()` call before `$enc->close()` for a `notes.md` entry, then call `print_r( $zip->ls( '/' ) )` at the end. The directory listing reflects the new entry without re-reading the file.
