ZipStream PHP
|
||
|
|
=============
|
||
|
|
|
||
|
|
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.

Installation
|
||
|
|
---------------
|
||
|
|
|
||
|
|
Simply add a dependency on ``maennchen/zipstream-php`` to your project's
|
||
|
|
``composer.json`` file if you use Composer to manage the dependencies of your
|
||
|
|
project. Use following command to add the package to your project's dependencies:
|
||
|
|
|
||
|
|
.. code-block:: sh
|
||
|
|
composer require maennchen/zipstream-php
|
||
|
|
|
||
|
|
Usage Intro
|
||
|
|
---------------
|
||
|
|
|
||
|
|
Here's a simple example:
|
||
|
|
|
||
|
|
.. code-block:: php
|
||
|
|
|
||
|
|
// Autoload the dependencies
|
||
|
|
require 'vendor/autoload.php';
|
||
|
|
|
||
|
|
// enable output of HTTP headers
|
||
|
|
$options = new ZipStream\Option\Archive();
|
||
|
|
$options->setSendHttpHeaders(true);
|
||
|
|
|
||
|
|
// create a new zipstream object
|
||
|
|
$zip = new ZipStream\ZipStream('example.zip', $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');
|
||
|
|
|
||
|
|
// add a file named 'goodbye.txt' from an open stream resource
|
||
|
|
$fp = tmpfile();
|
||
|
|
fwrite($fp, 'The quick brown fox jumped over the lazy dog.');
|
||
|
|
rewind($fp);
|
||
|
|
$zip->addFileFromStream('goodbye.txt', $fp);
|
||
|
|
fclose($fp);
|
||
|
|
|
||
|
|
// finish the zip stream
|
||
|
|
$zip->finish();
|
||
|
|
|
||
|
|
You can also add comments, modify file timestamps, and customize (or
|
||
|
|
disable) the HTTP headers. It is also possible to specify the storage method
|
||
|
|
when adding files, the current default storage method is ``DEFLATE``
|
||
|
|
i.e files are stored with Compression mode 0x08.
|
||
|
|
|
||
|
|
Known Issues
|
||
|
|
---------------
|
||
|
|
|
||
|
|
The native Mac OS archive extraction tool prior to macOS 10.15 might not open
|
||
|
|
archives in some conditions. A workaround is to disable the Zip64 feature with
|
||
|
|
the option ``enableZip64: false``. This limits the archive to 4 Gb and 64k files
|
||
|
|
but will allow users on macOS 10.14 and below to open them without issue.
|
||
|
|
See `#116 <https://github.com/maennchen/ZipStream-PHP/issues/146>`_.
|
||
|
|
|
||
|
|
The linux ``unzip`` utility might not handle properly unicode characters.
|
||
|
|
It is recommended to extract with another tool like
|
||
|
|
`7-zip <https://www.7-zip.org/>`_.
|
||
|
|
See `#146 <https://github.com/maennchen/ZipStream-PHP/issues/146>`_.
|
||
|
|
|
||
|
|
It is the responsability of the client code to make sure that files are not
|
||
|
|
saved with the same path, as it is not possible for the library to figure it out
|
||
|
|
while streaming a zip.
|
||
|
|
