Can send an array to the server, how to receive data?

Http://www.workerman.net/workerman-chat
Can look at this, php written websocket chat room, customer service function can actually be used inside the single chat function. Someone uses it to implement a passer-by, including web pages and client software.
Development manual: Http://workerman.net/gatewaydoc/
demo:http://chat.workerman.net/

Baidu on the PHP websocket tutorial has enough, you can go to see.
