ssl - how to make websocket secure connection in php socket -

i making chatroom using websockets, working fine when use unencrypted connection, after use certificate doesn't work anymore.

in javascript opening connection websocket server @ serverr.php this:

var wsuri = "ws://mydomain.com:9002/chat/serverr.php";  websocket1 = new websocket(wsuri); 

now know must use wss:// instead of ws:// using:

var wsuri = "wss://mydomain.com:9002/chat/serverr.php"; websocket1 = new websocket(wsuri); 

but following error:

websocket connection 'wss://mydomain.com:9002/chat/serverr.php' failed: error in connection establishment: net::err_ssl_protocol_error

but don't know how make wss:// connection. tried modify code following part:

set_time_limit(0);  require_once($_server['document_root']."../../../home/username/public_html/config/config.php");   $host = 'ssl://0.0.0.0'; //host $port = '9002'; //port $null = null; //null var  // generate certificate $privkey = openssl_pkey_new(); $cert    = openssl_csr_new($dn, $privkey); $cert    = openssl_csr_sign($cert, null, $privkey, 365);  // generate pem file # optionally change passphrase 'comet' whatever want, or leave empty no passphrase $pem_passphrase = 'comet'; $pem = array(); openssl_x509_export($cert, $pem[0]); openssl_pkey_export($privkey, $pem[1], $pem_passphrase); $pem = implode($pem);  // save pem file $pemfile = 'server.pem'; file_put_contents($pemfile, $pem);   //create tcp/ip sream socket $socket = socket_create(af_inet, sock_stream, sol_tcp); //reuseable port socket_set_option($socket, sol_socket, so_reuseaddr, 1); socket_set_option($socket, sol_socket, 'ssl', 'local_cert', $pemfile); socket_set_option($socket, sol_socket, 'ssl', 'passphrase', $pem_passphrase); socket_set_option($socket, sol_socket, 'ssl', 'allow_self_signed', true); socket_set_option($socket, sol_socket, 'ssl', 'verify_peer', false);  //bind socket specified host socket_bind($socket, 0, $port); //the rest of code still unmodified in page serverr.php
