php同時使用session和cookie來儲存使用者登入資訊的實現代碼_php執行個體

1、使用者登入狀態操作類UserLogin

<?phpfinal 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、在使用者輸入使用者名稱、密碼處調用來做相關判定

<?phprequire_once 'Init.php';// if logged in, logoutif (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($user);  Flash::addFlash('登入成功！');  Utils::redirect('welcome'); }  foreach ($errors as $e) {  $msg .= $e->getMessage()."<br>"; }}?>
