How to generate a PDF file from HTML or modify an existing one?

Question

PHP

I need to generate a PDF file - something like an invoice.
Are there any options to create a PDF with placeholders and replace them with the desired data and save?
If not, is it possible to somehow generate PDF from HTML without much hemorrhoids?
I tried various options:
1) FPDF paired with FPDI - it didn't start for me. The output always produced a corrupted file that could not be opened. Moreover, in the PDF output mode, a bunch of warnings about dividing by 0 flew out to the browser ...

The code

$pdf = new FPDI();

    $pdf->addPage();

    $pageCount = $pdf->setSourceFile("templ.pdf");
    $tplIdx = $pdf->importPage(1);

    $pdf->useTemplate($tplIdx, 0, 0, 0, 0, true);

    $pdf->Output('test.pdf','F');

2) TCPDF - in principle, it works. But CSS support is very weak. Even banal paddings are not set (at least I did not succeed ... )

"Are there any options to create a PDF with placeholders and replace them with the desired data and save?"
Yes, something like that is possible. You can immediately generate a finished PDF using FPDF.
"If not, is it possible to somehow generate PDF from HTML without much hemorrhoids?"
- Yes, you can. You form html for printing, and then in FF using doPDF you convert to pdf
