PHP Session Exit Login Problem

This article is mainly on the PHP session out of the landing problem was introduced, the need for friends can come to the reference, I hope to help you

In PHP, if you use the session to determine whether the user login, exit, you can: Session_Start ();   Session_destroy (); The session indicates that it has ended.   Next sentence should write JS, so that the page jump. <script>alert ("The landing has been withdrawn!") location.href= "login.php";</script> if it is a frames page, do not use location directly. Because this will be in a small frame page to jump, the intention must be to the entire frame to jump past ah.   So location before you add "parent." All processes are as follows (for frames pages only): The code is as follows: <?php session_start (); Session_destroy (); To enable the entire page of the frame to jump to the landing page echo "<script>alert (' has withdrawn from landing ');p arent.location.href= ' login.php ';</script>";?>
