I try to run a websocket application (php-based chat) and need to get the Sec-WebSocket-Key out of the Handshake header I get by executing:
$socket_new = socket_accept($socket);
$header = socket_read($socket_new, 5000);
But the needed Attribute is missing in my header... here you can see the print of the revieved header. The WebSocket client normally should set this param itself?!

I tried it with Firefox and Chrome and my Server runs on an Debian server. Do I need to install something on my server (like any WebSocket lib) ?
Or why are the Sec-WebSocket Attributes missing?
