php同時使用session和cookie來保存用戶登錄信息的實現(xiàn)代碼

    下面小編就為大家?guī)硪黄猵hp同時使用session和cookie來保存用戶登錄信息的實現(xiàn)代碼。小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個參考
    1、用戶登錄狀態(tài)操作類UserLogin
    <?php
    final class UserLogin {
     public function __construct() {
     }
     public static function getUserInfo() {
      if (isset($_COOKIE["user_id"])&&$_COOKIE["user_id"]&&(trim($_COOKIE["user_id"])!="")) {
       if (isset($_SESSION["USER_INFO"]))
        return $_SESSION["USER_INFO"];
       $dao = new UserDao();
       $user = $dao->find($_COOKIE["user_id"]);
       if ($user) {
        $_SESSION["USER_INFO"] = $user;
        setcookie("docloud_sid", session_id(), time() + 36000);
        setcookie("user_id", $_COOKIE["user_id"], time() + 36000);
        if (array_key_exists("selected_prj_id", $_COOKIE))
         setcookie("selected_prj_id", $_COOKIE["selected_prj_id"], time() + 36000);
        if (array_key_exists("selected_class_id", $_COOKIE))
         setcookie("selected_class_id", $_COOKIE["selected_class_id"], time() + 36000);
        if (array_key_exists("selected_image_id", $_COOKIE))
         setcookie("selected_image_id", $_COOKIE["selected_image_id"], time() + 36000);
        if (array_key_exists("test_image_ids", $_COOKIE))
         setcookie("test_image_ids", $_COOKIE["test_image_ids"], time() + 36000);
        if (array_key_exists("upload_image_ids", $_COOKIE))
         setcookie("upload_image_ids", $_COOKIE["upload_image_ids"], time() + 36000);
        return $user;
       }
      }
      self::clearCookie();
      return null;
     }
     public static function setUserInfo($userInfo) {
      $_SESSION["USER_INFO"] = $userInfo;
      setcookie("docloud_sid", session_id(), time() + 36000);
      setcookie("user_id", $userInfo->getId(), time() + 36000);
     }
     public static function isLogin() {
      if (self::getUserInfo()) {
       return true;
      }
      return false;
     }
     public static function delUserInfo() {
      self::clearCookie();
      session_destroy();
     }
     private static function clearCookie() {
      setcookie("docloud_sid", "", time() - 36000);
      setcookie("user_id", "", time() - 36000);
      setcookie("selected_prj_id", "", time() - 36000);
      setcookie("selected_class_id", "", time() - 36000);
      setcookie("selected_image_id", "", time() - 36000);
      setcookie("test_image_ids", "", time() - 36000);
      setcookie("upload_image_ids", "", time() - 36000);
     }
    }
    ?>
    2、在用戶輸入用戶名、密碼處調(diào)用來做相關(guān)判定
    <?php
    require_once 'Init.php';
    // if logged in, logout
    if (UserLogin::isLogin() && $_COOKIE["user_id"]==1) {
     UserLogin::delUserInfo();
    }
    else if (UserLogin::isLogin()){
     Utils::redirect('welcome');
    }
    $username = null;
    $password = null;
    $msg = "";
    if (isset($_POST['username']) && isset($_POST['password'])) {
     $username = addslashes(trim(stripslashes($_POST ['username'])));
     $password = addslashes(trim(stripslashes($_POST ['password'])));
     // validate
     $errors = LoginValidator::validate($username, $password);
     if (empty($errors)) {
      // save
      $dao = new UserDao();
      $user = $dao->findByName($username);
      $last_login_ip = Utils::getIpAddress();
      $user->setLastLoginIp($last_login_ip);
      $now = new DateTime();
      $user->setLastLoginTime($now);
      $dao->save($user);
      UserLogin::setUserInfo($user);
      Flash::addFlash('登錄成功！');
      Utils::redirect('welcome');
     }
     foreach ($errors as $e) {
      $msg .= $e->getMessage()."<br>";
     }
    }
    ?>
