How to send a pdf string to be printed?

Question

PHP

I use the dompdf class .
I found two methods for outputting pdf:

1. $dompdf->stream(); // скачивает пдф в браузере
2. $dompdf->output(); // возвращает пдф как строку

With the second I don’t understand how it works, the browser does not display anything.
I need something to open the PDF in the browser (for further printing or downloading).
How to achieve this?

Answer 1

output - returns pdf as a string. And stream is just the opposite, outputs to the browser
