Question

下面的一个是我的php网站中的链接..点击此按钮后，用户的会话应该被终止，他应该被重定向到主页..我已经编写了这个概念的编码如下，但它显示我只是一个空白页面（它没有重定向到主页）.. 请更正我的编码

<a href="Logout.php">
click here to log out</a>

Logout.php中的编码如下

<?
session_start();
session_unset();
session_destroy();
ob_start();
header("location:home.php");
ob_end_flush(); 
include 'home.php';
//include 'home.php';
exit();
?>

Answer 1

只有这是必要的

session_start();
unset($_SESSION["nome"]);  // where $_SESSION["nome"] is your own variable. if you do not have one use only this as follow **session_unset();**
header("Location: home.php");

请改用：

<?
session_start();
session_unset();
session_destroy();

exit();

Answer 5

<?php //initialize the session if (!isset($_SESSION)) {   session_start(); } 
// ** Logout the current user. **
$logoutAction = $_SERVER['PHP_SELF']."?doLogout=true";
if ((isset($_SERVER['QUERY_STRING'])) && ($_SERVER['QUERY_STRING'] != "")){
    $logoutAction .= "&". htmlentities($_SERVER['QUERY_STRING']); 
}

if ((isset($_GET['doLogout'])) &&($_GET['doLogout']=="true")) {
    // to fully log out a visitor we need to clear the session variables
    $_SESSION['MM_Username'] = NULL;
    $_SESSION['MM_UserGroup'] = NULL;
    $_SESSION['PrevUrl'] = NULL;
    unset($_SESSION['MM_Username']);  
    unset($_SESSION['MM_UserGroup']);
    unset($_SESSION['PrevUrl']);
    $logoutGoTo = "index.php";

    if ($logoutGoTo) {
        header("Location: $logoutGoTo");
        exit;
    }
} ?>

注销并重定向回登录名或索引的最简单方法：

<?php
    if (!isset($_SESSION)) { session_start(); }
    $_SESSION = array(); 
    session_destroy(); 
    header("Location: login.php"); // Or wherever you want to redirect
    exit();
?>

在php中注销和重定向会话
