How to get printed PDF document from byte array?

Question

PHP

Good day! We have to download printed forms, receipts, invoices, etc. using the supplier's API. The response to the request returns an array of bytes, format and file extension. In this case, I'm trying to get a printable PDF of a receipt. How can I convert this byte array into a normal printed document?

Answer 1

Create a file with the desired extension, open it for writing, write an array of bytes. Then give this file for download

Answer 2

Save this array to a file, obviously.
