Hi, I am currently struggling with returning a docx as a stream in a symfony app.

Here is what i got 

 

#[Route('/', name: 'app_app')]
public function index(): StreamedResponse
{
    $doc = new CreateDocx();
    CreateDocx::$streamMode = true;
    CreateDocx::$returnDocxStructure = true;

    $doc->addText('This is a test');
    $doc->embedHTML('<p style="font-size: 30px;">New paragraph</p>');

    return new StreamedResponse(function () use ($doc) {
        $stream = fopen('php://output', 'wb');
        stream_copy_to_stream($doc, $stream);
    });
}

 

Of course this cannot work since the $doc in my stream_copy_to_stream is not a resource. How can i transform it as a resource.

Also can you correct the way i am trying to retrieve the document from the API:

 

public function index(HttpClientInterface $http): Response
{
    $response = $http->request(Request::METHOD_GET, 'https://dev.doc.ey');

    $doc = new DOCXStructureFromStream;
    $doc->generateDOCXStructure($response->getContent());

    dd($doc);

    return $this->render('app/index.html.twig', [
        'controller_name' => 'AppController',
    ]);
}

 

Thanks in advance

Hello,

To generate a DOCX as a stream you need to enable the streamMode option (https://www.phpdocx.com/api-documentation/performance/zip-stream-docx-with-PHP). For example:

$docx = new CreateDocx();

CreateDocx::$streamMode = true;

$docx->addText($'Text mode.');

$docx->createDocx('output');

In this streamMode, when you call createDocx, the DOCX is generated as a stream, so after calling this method (createDocx) you can do anything you need with this stream.

If you enable $returnDocxStructure you are working with in-memory DOCX documents, not streams. An in-memory DOCX document is not a stream but an object that you can serialize or reuse instead of generating the file. On https://www.phpdocx.com/documentation/cookbook/in-memory-docx-documents you can read more information about working with in-memory DOCX documents

About using generateDOCXStructure, this method generates a DOCXStructure (this is an in-memory DOCX document) from a DOCX stream. This DOCXStructure is an in-memory DOCX document that can be used as template with CreateDocxFromTemplate and with other phpdocx methods.
Using phpdocx you can work with DOCX documents from the filesystem, as in-memory DOCX documents (https://www.phpdocx.com/documentation/cookbook/in-memory-docx-documents) or as streams (https://www.phpdocx.com/api-documentation/performance/zip-stream-docx-with-PHP).

We recommend you check the examples/Performance folder included in the Premium package that illustrate using generateDOCXStructure, parseDocx, returnDocxStructure and zipStream.

On https://www.phpdocx.com/en/forum/default/topic/2091 you can read a topic with the same stream question and how the user implemented it.

Regards.

Hey again,

I appologize in advance but i've been looking at all the examples and the other related topics from the forum but i still dont understand how to stream a docx from an api and retrieve it from another app. Would it be possible to have an actual fully working example ideally with symfony.

here is what i got so far:

 

The API endpoint

use Phpdocx\Create\CreateDocx;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\StreamedResponse;
use Symfony\Component\Routing\Annotation\Route;

class AppController extends AbstractController
{
    #[Route('/', name: 'app_app')]
    public function index(): StreamedResponse
    {
        $doc = new CreateDocx();
        CreateDocx::$streamMode = true;

        $doc->addText('This is a test');
        $doc->embedHTML('<p style="font-size: 30px;">New paragraph</p>');

        return new StreamedResponse(function () use ($doc) {
            $doc->createDocx('output1');
        });
    }
}

 

and the front.

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Contracts\HttpClient\HttpClientInterface;

class AppController extends AbstractController
{
    #[Route('/', name: 'app_home')]
    public function index(HttpClientInterface $http): Response
    {
        $response = $http->request(Request::METHOD_GET, 'https://dev.doc.ey');
        $doc = $response->getContent();

        dd($doc);

        return $this->render('app/index.html.twig', [
            'controller_name' => 'AppController',
        ]);
    }
}

Hello,

Sorry, but we don't have a whole sample using a stream with Symfony. phpdocx can be used with any PHP project, CMS, framework... the stream is generated as a generic stream.

We recommend you check the Symfony documentation about working with streams available on:

https://dev.to/rubenrubiob/serve-a-file-stream-in-symfony-3ei3

https://symfony.com/doc/current/components/http_foundation.html#serving-files

and also test step by step your code: if the DOCX stream is generated and returned correctly, if the stream is being captured correctly (and then if you can save as a fs or stream it).

Regards.
