How can the user modify the code to only output users in the "lobby" room?

To only output users in the "lobby" room, we can modify the code to check if the user's room is equal to "lobby" before outputting their information. This can be done by adding an if statement to filter out users in other rooms. 

// Assuming $users is an array of user objects with 'name' and 'room' properties

foreach ($users as $user) {
    if ($user['room'] == 'lobby') {
        echo $user['name'] . " is in the lobby room." . PHP_EOL;
    }
}
