Can php receive and immediately process part of a request without waiting for the request to finish receiving?

Question

PHP

If a gray IP server sends a request to a white IP server, can the white IP server send a response indefinitely, thus creating a persistent tunneling connection?
Can php receive and immediately process part of the request without waiting for the end of receiving the request, since one server response lasts forever and, of course, it must be processed in parts?

Answer 1

as you wrote in your other question - better use the nodejs net module - and you can easily create long-lived sockets and process data as it arrives, without dancing with tambourines.
If you don't live, you don't need to be in php, then it's better to move towards sockets. use for example phpDaemon or any equivalent.
well, another hardcore option that works out of the box is the implementation of sockets, it also works with pzp 4
