README
A ZIP responder (PSR-7).
Table of Contents
Requirements
- PHP 7.3+ or 8.0+
- A PSR-7 StreamFactory implementation, e.g. nyholm/psr7
Installation
composer require selective/zip-responder
Usage
Creating a new ZipResponder instance using the nyholm/psr7
Psr17Factory:
use Selective\Http\Zip\ZipResponder; use Nyholm\Psr7\Factory\Psr17Factory; $zipResponder = new ZipResponder(new Psr17Factory());
Creating a new ZipResponder instance using the slim/psr7
StreamFactory:
use Selective\Http\Zip\ZipResponder; use Slim\Psr7\Factory\StreamFactory; $zipResponder = new ZipResponder(new StreamFactory());
Sending a ZIP file
Send ZIP file to browser, force direct download:
return $zipResponder->withZipFile($response, 'source.zip', 'output.zip');
Sending a ZIP file from a string
return $zipResponder->withZipString($response, file_get_contents('example.zip'), 'output.zip');
Sending a ZIP stream
Send ZIP stream to the browser, force direct download:
$stream = fopen('test.zip', 'r'); return $zipResponder->withZipStream($response, $stream, 'output.zip');
Sending a ZIP stream on the fly
Sending a file directly to the client is not intended according to the PSR-7 specification, but can still be realized with the help of a CallbackStream.
use Selective\Http\Zip\Stream\CallbackStream; $callbackStream = new CallbackStream(function () { echo 'my binary zip content'; } $response = $zipResponder->withZipHeaders($response, $outputName, true); return $response->withBody($callbackStream);
Sending a ZipArchive file
The ZIP extension enables you to transparently read or write ZIP compressed archives and the files inside them. A ZipArchive does not support "memory mapped files", like PHP streams. You can only access local files with ZipArchive. For this purpose, you can create a temporary file, or you can use an existing file from the filesystem.
use ZipArchive; // ... // Create temporary filename $filename = tempnam(sys_get_temp_dir(), 'zip'); // Add files to temporary ZIP file $zip = new ZipArchive(); $zip->open($filename, ZipArchive::CREATE | ZipArchive::OVERWRITE); $zip->addFromString('test.txt', 'my content'); $zip->close(); // Render ZIP file into the response as stream return $zipResponder->withZipStream($response, fopen($filename, 'r'), 'download.zip');
Sending a ZipStream-PHP archive
ZipStream-PHP is a library for streaming dynamic ZIP files without writing to the disk. You can send the file directly to the user, which is much faster and improves testability.
Installation:
composer require maennchen/zipstream-php
Creating and sending a ZIP file (only in-memory) to the browser:
use ZipStream\ZipStream; // ... // Create ZIP file, only in-memory $stream = fopen('php://memory', 'w+b'); $zip = new ZipStream( outputStream: $stream, // disable output of HTTP headers sendHttpHeaders: false, ); // create a file named 'hello.txt' $zip->addFile( fileName: 'hello.txt', data: 'This is the contents of hello.txt', ); $zip->finish(); $response = $zipResponder->withZipStream($response, $stream, 'download.zip');
Sending a ZIP-stream on the fly:
use Selective\Http\Zip\Stream\CallbackStream; use ZipStream\ZipStream; //... $callbackStream = new CallbackStream(function () { // Flush ZIP file directly to output stream (php://output) $zip = new ZipStream( flushOutput: true, sendHttpHeaders: false, ); // Add files to ZIP file and stream it directly $zip->addFile('test.txt', 'my file content'); $zip->addFile('test2.txt', 'my file content 2'); $zip->addFile('test3.txt', 'my file content 4'); $zip->finish(); }); $response = $zipResponder->withZipHeaders($response, $outputName, true); return $response->withBody($callbackStream);
Sending a PhpZip archive
PhpZip is a library for extended work with ZIP-archives.
Installation:
composer require nelexa/zip
Note, when you use the nelexa/zip
component, you may not need the selective/zip-responder
component because the nelexa/zip
already provides its own PSR-7 responder.
Example
use PhpZip\ZipFile; // ... $zipFile = new ZipFile(); $zipFile->addFromString('test.txt', 'File content'); return $zipFile->outputAsResponse($response, 'download.zip');
In case you want to keep your architecture more clean (SRP),
you may use the selective/zip-responder
responder to create
and send a ZIP file to the browser as follows:
use PhpZip\ZipFile; // ... // Create new archive $zipFile = new ZipFile(); // Add entry from string $zipFile->addFromString('test.txt', 'File content'); return $zipResponder->withZipString($response, $zipFile->outputAsString(), 'download.zip');
Slim 4 Integration
Create a DI container definition for: StreamFactoryInterface::class
and ZipResponder::class
A nyholm/psr7
and PHP-DI example:
<?php use Nyholm\Psr7\Factory\Psr17Factory; use Psr\Container\ContainerInterface; use Psr\Http\Message\StreamFactoryInterface; use Selective\Http\Zip\ZipResponder; return [ // ... StreamFactoryInterface::class => function (ContainerInterface $container) { return $container->get(Psr17Factory::class); }, ZipResponder::class => function (ContainerInterface $container) { return new ZipResponder($container->get(StreamFactoryInterface::class)); }, ];
A slim/psr7
and PHP-DI example:
<?php use Psr\Container\ContainerInterface; use Psr\Http\Message\StreamFactoryInterface; use Slim\Psr7\Factory\StreamFactory; use Selective\Http\Zip\ZipResponder; return [ // ... StreamFactoryInterface::class => function () { return new StreamFactory(); }, ZipResponder::class => function (ContainerInterface $container) { return new ZipResponder($container->get(StreamFactoryInterface::class)); }, ];
The responder should only be used within an action handler or middleware.
Action class example using dependency injection:
<?php namespace App\Action; use Psr\Http\Message\ResponseInterface; use Psr\Http\Message\ServerRequestInterface; use Selective\Http\Zip\ZipResponder; use ZipArchive; final class ZipDemoAction { /** * @var ZipResponder */ private $zipResponder; public function __construct(ZipResponder $zipResponder) { $this->zipResponder = $zipResponder; } public function __invoke( ServerRequestInterface $request, ResponseInterface $response ): ResponseInterface { $filename = tempnam(sys_get_temp_dir(), 'zip'); $zip = new ZipArchive(); $zip->open($filename, ZipArchive::CREATE | ZipArchive::OVERWRITE); $zip->addFromString('test.txt', 'my content'); $zip->close(); return $this->zipResponder->withZipFile($response, $filename, 'filename.zip'); } }
