There is only ftp access. How to find out the domain?

Question

Apache HTTP Server

There is only access to hosting via FTP, how to find out the domain address? There is nothing of the kind in the file structure itself.

Answer 1

Hosting does not necessarily mean having a domain.
Sometimes in the file structure, hosting puts files for different domains in folders with the name of the domain, but not the fact.
That is, no way.

Answer 2

how is that not possible? load a php script with simple content and execute it.
