Usage with PSR 7 Streams
PSR-7 streams are `standardized streams <https://www.php-fig.org/psr/psr-7/>`_.
ZipStream-PHP supports working with these streams with the function ``addFileFromPsr7Stream``.
For all parameters of the function see the API documentation.
Example
.. code-block:: php
$stream = $response->getBody(); // add a file named 'streamfile.txt' from the content of the stream $zip->addFileFromPsr7Stream('streamfile.txt', $stream);
