How to make friends PHP and Socket IO to the end?

Question

PHP

Hi all. Found such library elephant.io for PHP which connects it with Node JS server with Socket IO. Everything is set up and working. But I can't figure out how to read what came from the server... Sending is simple:

$version = new Version1X("http://localhost:7777");

$client = new Client($version);

$client->initialize();
$client->emit("new_message", ["Text"=>"Текст"]);

But reading ... I tried to make a simple function and call it on the server:
io.emit("NEW_MESSAGE", "text");

function NEW_MESSAGE(data)
{
   echo data;
}

But this didn’t work ...
I immediately say that regular JS on the client is not suitable, I want to make private messages and even I’m afraid for security, there’s the client side, you can change anything ...
Now, if that page on the github https:// github.com/shubhamparamhans/elephant.io

Answer 1

I say right away that regular JS on the client is not suitable

use websocket to communicate with it from the backend? well, then throw out the websocket, you don't need it.
