Question 1

How do I convert HTML to PDF using Gotenberg PHP?

Accepted Answer

Use the Chromium module's html() method with a Stream object for the HTML content, or the url() method for web pages, as demonstrated in the README examples. This sends a request to the Gotenberg API and returns a PDF response that can be saved directly.

Question 2

Gotenberg PHP vs Dompdf for PDF generation in PHP?

Accepted Answer

Gotenberg PHP relies on an external API for high-fidelity conversion from HTML and Office documents, offering better rendering accuracy, while Dompdf is a pure PHP library for basic HTML-to-PDF but with rendering limitations. Choose Gotenberg PHP for complex document processing, but Dompdf for simpler, offline use cases.

Question 3

Can I use Gotenberg PHP in a Laravel project?

Accepted Answer

Yes, it integrates well with Laravel due to its PSR compliance, and you can use Laravel's HTTP client or install an adapter like guzzle7-adapter. The fluent API aligns with Laravel's coding style, making it straightforward for common PDF generation tasks.

Question 4

How to handle errors when the Gotenberg API fails?

Accepted Answer

Catch the GotenbergApiErrored exception thrown by send() or save() methods, which includes correlation IDs for debugging. The README shows how to retrieve these IDs to trace issues in Gotenberg logs, aiding in production troubleshooting.

Question 5

Does Gotenberg PHP support merging multiple PDFs?

Accepted Answer

Yes, through the PDF Engines module, you can use methods like merge() to combine PDFs, as implied by the PDF manipulation endpoints. However, this depends on Gotenberg's underlying capabilities and requires proper request building with stream files.

Question 6

What are the performance implications of using Gotenberg PHP?

Accepted Answer

Performance is influenced by network latency and the Gotenberg instance's scalability, as each conversion involves HTTP requests. For high-volume applications, ensure the Gotenberg service is optimized and consider batch processing to mitigate overhead.
