如何实现用PHP记住我的功能而不覆盖会话行为

Question

我在测试项目中使用cookie时遇到问题，我正在尝试实现remember_me功能，如果用户在登录时单击了“记住我”按钮并在自动注销时保持用户登录30天如果在登录期间未单击按钮，浏览器将关闭。目前我正在做（connect.php文件）：问题是，无论他是否点击了“记住我”按钮，它目前都会让用户隐藏起来

<?php
ini_set('session.cookie_lifetime', 3600 * 24 * 30);
session_start();

//Our MySQL user account.
define('MYSQL_USER', 'root');

//Our MySQL password.
define('MYSQL_PASSWORD', '');

//The server that MySQL is located on.
define('MYSQL_HOST', 'localhost');

//The name of our database.
define('MYSQL_DATABASE', 'qh_beer_shop');

/**
 * PDO options / configuration details.
 * I'm going to set the error mode to "Exceptions".
 * I'm also going to turn off emulated prepared statements.
 */
$pdoOptions = array(
    PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
    PDO::ATTR_EMULATE_PREPARES => false
);

/**
 * Connect to MySQL and instantiate the PDO object.
 */
$pdo = new PDO(
    "mysql:host=" . MYSQL_HOST . ";dbname=" . MYSQL_DATABASE, //DSN
    MYSQL_USER, //Username
    MYSQL_PASSWORD, //Password
     $pdoOptions //Options
);
$pdo->query('SET NAMES utf8');

登录：

<?php
require_once 'connect.php';
if(isset($_SESSION['user'])) {
    header('Location: login.php');
    exit;
}
$error = '';

try {
//If the POST var "register" exists (our submit button), then we can
//assume that the user has submitted the registration form.
    if (isset($_POST['login'])) {

        $username = $_POST['username'];
        $password = $_POST['password'];

        //Retrieve the field values from our registration form.
        // $username = !empty($_POST['username']) ? trim($_POST['username']) : null;
        // $password = !empty($_POST['password']) ? trim($_POST['password']) : null;


//Construct the SQL statement and prepare it.
        $sql = "SELECT 
                id AS id,
                username AS username,
                password AS password,
                email AS email,
                phone AS phone,
                address AS address,
                first_name AS first_name,
                last_name AS last_name,
                age AS age             
            FROM
                users
            WHERE
                 username = ?
             ";
        $stmt = $pdo->prepare($sql);


        $stmt->execute([$username]);



        $user = $stmt->fetch(PDO::FETCH_ASSOC);


        $passwordHash = $user['password'];
        if (!password_verify($password, $passwordHash)) {
            setcookie('remember_me', '', time() - 100000);
            throw new Exception("Wrong username or password!");
        }

        $hour = time() + 3600;
        setcookie('ID_my_site', $_POST['username'], $hour);

        if($_POST['remember']) {
            $month = time() + 3600 * 24 * 30;
            setcookie('remember_me', $_POST['username'], $month);
        }
        elseif(!$_POST['remember']) {
            if(isset($_COOKIE['remember_me'])) {
                $past = time() - 100;
                setcookie('remember_me', '', $past);
            }
        }




        $_SESSION['id'] = $user['id'];
        $_SESSION['user'] = $user['username'];
        header('Location: profile.php');

    }
} catch (Exception $exception) {
    $error = $exception->getMessage();
}
