# Autoload the dependencies
require 'vendor/autoload.php';

# create a new zipstream object
$zip = new ZipStream('example.zip');

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

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

# add a file named 'goodbye.txt' from an open stream resource
$fp = tmpfile();
fwrite($fp, 'The quick brown fox jumped over the lazy dog.');
$zip->addFileFromStream('goodbye.txt', $fp);
fclose($fp);

# add a file named 'farewell.txt' from a PSR7 stream (e.g. Guzzle / AWS)
$amazonS3 = new Sdk()->createS3();
$file = $amazonS3->getObject(['Bucket' => 'bucket.name', 'Key' => 'path/to/farewell.txt']);

Some Caveats

64bit Zips don't work properly with macOS's default Zip library (i.e. used by the built-in unarchive). If you need >4GB Zips on mac, your users will need to use 3rd party software to unzip them. If your zip is going to be smaller, you can turn off 64bit support by calling:, _(*7)

$zip = new ZipStream('example.zip', [ZipStream::OPTION_USE_ZIP64 => false]);
