2. Session usage

a. After successful login, you need to create and record session

InitMySQL();
    $level = SelectUserLevel($helper,$name,$password);
    if($level != -1)
    {
        $result = $level;
        session_start();
        $_SESSION["user"] = true;
        $_SESSION["name"]=$name;
        $_SESSION["pwd"]=$password;
    }
    echo $result;
?>

b. Other functional modules use the specific method of session to write a general php. Other modules first call this php to determine whether to log in before calling.
