$user = User::getByUserName('john.doe'); echo $user->name; echo $user->email;
$user = User::getByUserName('jane.doe'); if ($user) { echo "User exists"; } else { echo "User does not exist"; }In this example, we are using the getByUserName method to check if a user with the username "jane.doe" exists in the database. If the user exists, the message "User exists" is printed to the screen; if the user does not exist, the message "User does not exist" is printed. This method is likely included in a package or library that provides functionality for user authentication and management. It is difficult to determine the specific package or library based on this method alone.
