セッションとCookieに基づいて記述されたPHPユーザーのログインステータス操作クラス

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;
 }
    パブリック静的関数 delUserInfo() {
 self::clearCookie();
 session_destroy();
 }

 プライベート静的関数 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、在用户入用户名、密码处调用来為相关判定

require_once 'Init.php';
// ログインしている場合はログアウトします
if (UserLogin::isLogin() && $_COOKIE["user_id"]==1) {
 U​​serLogin::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('登录成功！');
 Utils::redirect('welcome');
 }

 foreach ($errors as $e) {
 $msg .= $e->getMessage()."";
 }
}
