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.

$options = new ZipStream\Option\Archive();

// create a new zipstream object
$zip = new ZipStream\ZipStream('', $options);

// create a file named 'hello.txt'
$zip->addFile('hello.txt', 'This is the contents of hello.txt');

// add a file named 'some_image.jpg' from a local file 'path/to/image.jpg'
$zip->addFileFromPath('some_image.jpg', 'path/to/image.jpg');

// finish the zip stream

Upgrade to version 2.0.0

  • Only the self opened streams will be closed (#139) If you were relying on ZipStream to close streams that the library didn't open, you'll need to close them yourself now.

Upgrade to version 1.0.0

  • All options parameters to all function have been moved from an array to structured option objects. See the wiki for examples.
  • The whole library has been refactored. The minimal PHP requirement has been raised to PHP 7.1.

Usage with Symfony and S3

You can find example code on the wiki.


ZipStream-PHP is a collaborative project. Please take a look at the .github/ file.
