会话未正确结束

Question

所以通常我的会话应该在我按下页面上的注销按钮时结束，但是当我通过按钮（左上角）转到上一页时。我只是回到我登录的页面..This is my login page code<?php session_start();$errors = array();if(isset($_POST["name"]) and isset($_POST["password"])) {    $conn = mysqli_connect("localhost", "root", "123", "whoosh") or die("No connection made: ".mysqli_connect_error());    $name = $_POST["name"];    $password = $_POST["password"];    if (empty($name)) { array_push($errors, "Ename is required"); }    if (empty($password)) { array_push($errors, "Password is required"); }    if (count($errors) == 0) {        $query = "SELECT * FROM tbl_user WHERE name='$name' AND password='$password'";        $results = mysqli_query($conn, $query);        $user = mysqli_fetch_assoc($results);        if ($user) { // if user exists        if ($user['name'] === $name and $user['password'] === $password) {            $_SESSION['user'] = $user['id'];            header('location: mainsite.php');        }    }    }}?>This is the code I put on my main site thats allows me to logout.  <?php    session_start();   if(isset($_GET['logout'])){     $_SESSION['name'] = null;    header('Location:http://leopard.med.agfa.be/leopard/website/logIn.php');   }   session_destroy(); ?>那么，为什么我的会话不能正常工作并且没有完全注销？

Answer 1

试试这个！我没有看到您将名称传递给会话的任何地方。

if(isset($_GET['logout'])){

    // Initialize the session

       session_start();

    // Unset all of the session variables

       session_unset();

       $_SESSION = array();

    // Destroy the session.

        session_destroy();

        unset($_SESSION['user']);

    // Redirect to login page

        header('Location:http://leopard.med.agfa.be/leopard/website/logIn.php');

        exit();

}

注意：我使用了这两个unset()和destroy()功能，你可以使用一个。

将注销脚本更改为：

<?php

if(isset($_GET['logout'])){

    // null the _SESSION

    $_SESSION = null;

    // unset $_SESSION variable for the run-time 

    session_unset();

    // destroy session data in storage

    session_destroy();

    // last, redirect

    header('Location:http://leopard.med.agfa.be/leopard/website/logIn.php');

}

?>
