Ubuntu/CentOS difference in PHP usage

Question

I am trying to use an amazing library for websocket over SSL:
https://github.com/Devristo/phpws

Unfortunately it doesn't work on CentOS, but it works great on Ubuntu. It is not the version of PHP. I tried the same version on both OS and on Ubuntu works while on CentOS doesn't.

Answer 1

What exactly does it mean that it does not work? Are you getting errors, what happens when you run it?
The only requirements I see on Github are:

Server
- PHP 5.3
- Open port for the server
- PHP OpenSSL module to run a server over a encrypted connection

Client
- PHP 5.3
- Server that implements the HyBi (#8-#12) draft version
- PHP OpenSSL module to connect using SSL

If CentOs PHP version meets the requirements, I don't see a reason why it won't work.

Comments

I am suspecting the problem is in the OpenSSL library and I just discovered the one used in CentOS is not supporting TLSv1.2 while even the old Ubuntu is supporting!

Thanks for showing interest in my problem.
