I assumed the "client" is in fact a *server* which uses PHP to fetch
content from another server - and as the OP explained in
<cdd30e0e-1570-4ccf-bc50-7d35ac9a32c0@googlegroups.com>:

"I'm trying to identify the domain that is carrying out consultations in
my API.

The API is limited by domain, so I need to know which domain came the query"

So I hope it's clear that we are not talking about clients using their
dial-up-connections to run PHP scripts accessing the OPs web server.

See above.
