Create PHP WebSocket with SSL

Question

I have a websocket chat on my website and I recently added SSL certificate to my website. When I open my website with http , chat works. When I open it with https it's not working. I am using javascript as client for my chat with ws:// protocol. I changed that protocol to wss:// because of SSL encryption on my page, but it won't work that way. Here's part of my PHP server code that creates the socket:

$host = 'localhost'; 
$port = '9000'; 
$null = NULL;

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1);

socket_bind($socket, 0, $port);

socket_listen($socket);

$clients = array($socket);
