Hello @i-derevianko, firstly, thank you for your PR!

The user tested previous versions and confirmed that the code worked correctly.

What was the error that prompted the PR? Undefined properties?

For me, LGTM.

@walkor Do you agree?

[i-derevianko]

Hi @marcosmarcolin!
Yeah, undefined properties mostly, and problem with the parent class calling.

Found some problem. There is differences between release v2.0.3 and repo.

For example https://github.com/walkor/phpsocket.io/blob/master/src/Engine/Socket.php#L24

There is
public $upgradeTransport = null; public $transport = null;

But there is no this attributes in release v2.0.3. Check it please before merge.

Yes, after version v2.0.3 there were changes to the code, but a version was not released.

We can see all the changes after the mentioned version here: v2.0.3...master

@walkor I just released version v2.0.4 with the new changes.
