A server side alternative implementation of socket.io in PHP based on Workerman.
The socket extension implements a low-level interface to the socket communication functions based on the popular BSD sockets, providing the possibility to act as a socket server as well as a client.
For a more generic client-side socket interface, see stream_socket_client(), stream_socket_server(), fsockopen(), and pfsockopen().
When using these functions, it is important to remember that while many of them have identical names to their C counterparts, they often have different declarations. Please
be sure to read the descriptions to avoid confusion.
Only support socket.io v1.3.0 or greater.
This project is just translate socket.io by workerman.
More api just see http://socket.io/docs/server-api/
