This socket.io server do not support websocket protocol. Terminating connection...

[Pitel]

The following code ends with this exception:

require_once('ElephantIO/Client.php');
$elephant = new ElephantIO\Client('http://localhost:8000', $debug = true);
$elephant->init(true);

But it's not true! The following JS code works just fine in browser, and I am sure (from Chrome dev tools) it uses websocket protocol:

var socket = io.connect("http://localhost:8000");
socket.on("connect", function() {
    console.log("Connected!");
});

And here is the Node.js server:

var io = require("socket.io").listen(8000);
io.configure(function() {
    io.set("log level", 2);
    io.enable("browser client minification");
    io.enable("browser client etag");
    io.enable("browser client gzip");
});

So why am I getting the above exception?

Hi @Pitel , thanks for tryin' elephant.io!

We updated a bit the lib (2.0 tag) and unfortunately did not update the doc accordingly..

Could you please try these code parts and tell me if it works for you?

PHP Code trying to communicate with socket.io through PHP:

<?php

require('lib/ElephantIO/Client.php');
use ElephantIO\Client as ElephantIOClient;

$elephant = new ElephantIOClient('http://localhost:8000', 'socket.io', 1, false, true, true);

$elephant->init();
$elephant->send(
    ElephantIOClient::TYPE_EVENT,
    null,
    null,
    json_encode(array('name' => 'action', 'args' => 'foo'))
);
$elephant->close();

echo 'tryin to send `foo` to the event called action';

Node.js server

var io = require('socket.io').listen(8000);

io.sockets.on('connection', function (socket) {
  console.log('user connected');

  socket.on('action', function (data) {
    console.log('here we are in action event and data is: ');
    console.log(data);
  });
});

Oops, my bad. It seems PHP does not allow settings parameters like Python. Removing $debug = true from the constructor makes it work again. Sorry.

[dangquangminh]

how to remove $debug = true. I can fix this issue
