Multithreading, sockets, php?

Question

PHP

Kind.

There is a socket server in php, several clients connect to it, the order of communication is as follows:

клиент шлет серверу свой id<br/>
сервер отвечает, что id принят<br/>
клиент шлет серверу инфу<br/>
сервер отвечает, что инфа принята

I can’t understand how, in the case of a connection by several clients, to distinguish one from the other while saving data, because it can turn out like this:

cliend1id<br/>
client2id<br/>
client1data<br/>
client2data<br/>

accordingly, instead of the data of client 2, I will receive the data of client 1

Answer 1

Pay attention to the so-called "session mechanism", or at least "identifiers". Google, and even Wikipedia - both concepts.

Answer 2

thanks, the problem is that I didn’t find exactly the way to get the session ID
, only creating an array clientId=>socket connection resource comes to mind

Answer 3

For a socket server in php, you can take a specialized solution phpDaemon or nanoserv.
The last user used it himself, all users are separated by sockets and nothing gets mixed up anywhere)

Answer 4

Why don't you send the ID along with the data? Browsers do just that, oddly enough.
