  PHP library allowing thumbnail, snapshot or PDF generation from a url or a html page. Wrapper for wkhtmltopdf/wkhtmltoimage (by KnpLabs)

  

When I first looked for solutions to generate a PDF document in a Symfony application, I was amazed to find that a SymfonyCast was made about this. It features the PHP library Snappy, which is essentially a wrapper around wkhtmltopdf.

  Easily create PDF in Symfony by converting HTML using WeasyPrint

  

The advantage of this approach is that it can be used as a command-line tool with other languages, just like the bundle for Symfony that I will present in this article!

• Twig

  Twig, the flexible, fast, and secure template language for PHP

  

The first step before generating the PDF is writing the HTML. To generate the HTML string, we will use the Twig template engine, which is the default one in Symfony. It comes with tons of features such as inheritance, blocks, filters, functions, and more.

Performance is not the strength of WeasyPrint, meaning that heavy HTML files will increase generation time. You should always compress images before attaching them, as they are not compressed by default. Generating a 50-page-long PDF may take up to a minute in extreme cases, although multi-page documents generated on my project take fewer than 2 seconds to generate.
