Elephant.io Error: Undefined offset: 3 in /var/www/lib/ElephantIO/Client.php on line 327 about elephant.io HOT 4 CLOSED

In the latest version, the line 327 points to a blank line.

Which version of socket.io are you using ?

from elephant.io.

Undefined offset: 3 in /var/www/lib/ElephantIO/Client.php on line 327

I think to line 336 of /lib/ElephantIO/Client.php.

$sess = explode(':', $res);
// ...
$this->session['supported_transports'] = array_flip(explode(',', $sess[3]));

When $res is "60:60:60" or "60::", it is error.

Therefore, I think like next.

$sess = explode(':', $res, 4);
if (count($sess) === 4) {
    $this->session['sid'] = $sess[0];
    $this->session['heartbeat_timeout'] = $sess[1];
    $this->session['connection_timeout'] = $sess[2];
    $this->session['supported_transports'] = array_flip(explode(',', $sess[3]));

    if (!isset($this->session['supported_transports']['websocket'])) {
        throw new \Exception('This socket.io server do not support websocket protocol. Terminating connection...');
    }
} else {
    return false;
}

I was using socket.io 1.0.6 , I changed it into 0.9.16 and now its working fine, for the first 2-5 minutes after restarting the node.js server it started showing info: undefined socket url and later it vanished. Anyway its working fine now, Thanks everyone for your help.

So yeah, the lib is not yet compatible with 1.X versions of Socket.IO. We working on it with the refacto-3.0 branch :)
