file_put_contents('invoice.pdf', $pdf);

pdf engines

Dompdf includes three engines
- CPDF (bundled with Dompdf)
- PDFLib is a commercial library with more advanced rendering than CPDF. It takes the form of a php extension that you will need to add to your php configuration.
- GD will produce a pdf containing an image
wk<html>topdf

To use the wk<html>topdf engine, you will need to download the binary for your system and add it to the current working directory getcwd() or to the system path.

Twig templates reference documentation

https://twig.symfony.com/doc/3.x/

custom fonts

Fonts can either be provided as a style sheet link in the html head, which requires the isRemoteEnabled permission:

<link href="https://fonts.googleapis.com/css2?family=Noto+Sans:wght@300;700&display=swap" rel="stylesheet">

or from the local drive using css, but only in TrueType *.ttf format:

@font-face {
    font-family: 'Tangerine';
    src: url('../fonts/tangerine-400.ttf');
    font-weight: normal;
}

@font-face {
    font-family: 'Tangerine';
    src: url('../fonts/tangerine-700.ttf');
    font-weight: bold;
}

I would recommend you use the second variant in production.

support more languages

A font supports a limited number of languages, and therefore if you want to support many different languages, you will need to add fonts that have the glyphs for the language characters. Here's an example where the default font is Segoe UI (latin languages), then it falls back to Meiyro UI for Japanese, and Malgun Gothic for Korean:

font-family: 'Segoe UI', 'Meiryo UI', 'Malgun Gothic', sans-serif;

If the font does not support the language, you will see small squares instead of the correct characters. These are called tofu because they resemble small blocks of tofu.
