How to fill the background of a png image using php?

Question

PHP

Actually the essence of the issue is that there is an image and you need to fill it in on the server with a color that arrives via AJAX from the client side. I would be very grateful to experienced php developers for a selection of functions for this task or code examples.
Thank you!
