extra informations

[rashcms]

Is it possible to receive extra information from the client ?
For example :

$socket->on('add user', function ($username) use($socket){
        global $usernames, $numUsers;
        // we store the username in the socket session for this client
        $socket->username = $username;
        // add the client's username to the global list
        $usernames[$username] = $username;
        ++$numUsers;
        $socket->addedUser = true;
        $socket->emit('login', array( 
            'numUsers' => $numUsers
        ));
        // echo globally (all clients) that a person has connected
        $socket->broadcast->emit('user joined', array(
            'username' => $socket->username . ' and extra information is : ' . $socket->extra,
            'numUsers' => $numUsers
        ));
    });

How to send and recive $socket->extra ?

Yes you can, for example transtransmission extra information of age.

Javascript side.

socket.emit('add user', {name: 'tom', age: 13});

Server side.

$socket->on('add user', function ($user_info) use($socket){
        global $usernames, $numUsers;
        // we store the username in the socket session for this client
        $username = $user_info['name'];
        $socket->username = $username;

        // =====Here get age form client======
        $age = $user_info['age'];

        // add the client's username to the global list
        $usernames[$username] = $username;
        ++$numUsers;
        $socket->addedUser = true;
        $socket->emit('login', array( 
            'numUsers' => $numUsers
        ));
        // echo globally (all clients) that a person has connected
        $socket->broadcast->emit('user joined', array(
            'username' => $socket->username,
            'numUsers' => $numUsers,
            'age'           => $age, // ====== extra information of age =====
        ));
    });
