在PHP中設置的Cookie;但沒有被發現？

Question

當用戶登錄時，這裏是我的用戶功能：

public function login($user) { 
    global $database; 
    if ($user) { 

     $_SESSION['user_id'] = $user->id; 
     $this->user_id = $_SESSION['user_id']; 

     $_SESSION['username'] = $user->username; 
     $this->username = $_SESSION['username']; 

     setcookie('user_id', $this->user_id, time() + (60 * 60 * 24 * 14)); 
     setcookie('username', $this->username, time() + (60 * 60 * 24 * 14)); 

     $this->logged_in = true; 

    } 
} 

當我看Cookiees在Chrome中，我找到兩個與此餅乾：
1 USER_ID，1用戶名。

但是，當瀏覽器被關閉，我試圖回來，它不會檢測cookiee：這裏的過程是：

class Session { 

    // Most of the class has been edited out; the code above is also a method in this clas. Removed so it's not duplicated. 


    private $logged_in = false; 
    public $user_id; // yes I realize this is insecure 
    public $username; // yes I realize this is insecure 

    function __construct() { 
      session_start(); 
      $this->check_login(); 
    } 

    public function is_logged_in() { 
     return $this->logged_in; 
    } 

    private function check_login() { 

    if (isset($_COOKIE['user_id']) && (isset($_COOKIE['username']))) { 
     $_SESSION['user_id']= $_COOKIE['user_id']; 
     $_SESSION['username'] = $_COOKIE['username']; 

    } else { // When I test, below shows up showing it doesn't think Cookie is set. 
     echo "Cookie not set in check_login().<br />"; 
    } 

    if (isset($_SESSION['user_id'])) { 
     $this->user_id = $_SESSION['user_id']; 
     $this->username = $_SESSION['username']; 
     $this->logged_in = true; 
    } else { 
     unset($this->user_id); 
     $this->logged_in = false; 

    } 
    } 

$session = new Session(); 

}

嘗試設置的路徑和域。

setcookie('user_id', $this->user_id, time() + 3600, '/', '.yourdomain.com'); 

如果您將路徑留空，該cookie將僅在當前目錄內處於「活動」狀態。例如，如果您的登錄腳本是http://example.com/user/login.php，那麼當您打開http://example.com時，瀏覽器將不會設置Cookie。
