Question

我遇到了问题。当我点击<a href="logout.php"> Logout </a>时，我有一个重定向到 login.php ，但是如果我再次打开 home.php ，那么没有重定向和用户留在系统。我的意思是没有会话毁灭。这是代码：

的login.php

<?php
session_start();
if (isset($_POST['submit']))
    {     
include("config.php");


$username=$_POST['username'];
$password=$_POST['password'];

$_SESSION['login_user']=$username;

$query = mysql_query("SELECT username FROM login WHERE username='$username' and password='$password'");

 if (mysql_num_rows($query) != 0)
{

 echo "<script language='javascript' type='text/javascript'> location.href='home.php' </script>";   
  }

  else
  {
echo "<script type='text/javascript'>alert('User Name Or Password Invalid!')</script>";
}

}

?>

home.php

<html>
<head>
<title>Untitled Document</title>
</head>
<body>    
<h1>Welcome 
<?php 
session_start();
$login_session=$_SESSION['login_user'];
echo $login_session;?> </h1>
<a href="logout.php"> Logout </a>
</body>
</html>

logout.php

<?php
session_start();
if(session_destroy())
{
header("Location: login.php");
}
?>

用户授权php / mysql与会话
