Is it possible to somehow create a site with a php file on github or is there another platform using php?

Question

PHP

hello. I recently used hostronavt.ru free hosting. but, since I had a free plan, I could not install an ssl certificate. then I found that you can create sites on github with your own subdomain and there is already a secure https connection. but again the problem: it is not possible to open php files.

I have two requests:
how to open php files on github?
or tell me if there are any other platforms or hostings with the ability to create your own subdomain and with an ssl certificate, and, accordingly, for free.

Answer 1

If it is possible to edit DNS records, you can use the free CloudFlare plan, which will include SSL

Answer 2

In my opinion, Beget allows you to use Let'sEncrypt certificates on a free plan. But this is not certain - it was a long time ago.
