关于PHP网页用户登陆后显示注销.而登陆前则只显示注册登陆连接的问题
如题.我是用PHP的.



    session_start();
    echo $_SESSION['username']; 
    ?>
  • Login

  • Apply for user1

  • Apply for user2



------------以上是在index.php写的------------

我是想当登陆后.login , Apply for user1 , Apply for user2都不显示.只显示用户名和注销.
然后注销后就会显示回login , Apply for user1…….
求大神们教教我.
