PHP uses both session and cookie to save the user login information implementation code, Sessioncookie

1. User Login state Operation class Userlogin

<?phpfinal class Userlogin {public Function __construct () {} public static function GetUserInfo () {if (Isset ($_co okie["user_id"]) &&$_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, the user entered the user name, password to make the relevant decision

<?phprequire_once ' init.php ';//If logged in, Logoutif (Userlogin::islogin () && $_cookie[ "USER_ID"]==1) {userlogin::d eluserinfo ();} else if (Userlogin::islogin ()) {Utils::redirect (' Welcome ');} $username = null, $password = NULL, $msg = "", if (isset ($_post[' username ') ") && isset ($_post[' password '])) {$userna me = 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 ($user); Flash::addflash (' Login successful!  '); Utils::redirect (' welcome '); } foreach ($errors as $e) {$msg. = $e->getmessage (). " 
 ";}}? 

This PHP at the same time using the session and cookie to save the user login information implementation code is small to share all the content of everyone, I hope to give you a reference, but also hope that we have a lot of support to help guests home.
