注销PHP脚本 [英] Logout PHP Script

问题描述

这是我的脚本:

<?php
  // If the user is logged in, delete the session vars to log them out
  session_start();
  if (isset($_SESSION['user_id'])) {
    // Delete the session vars by clearing the $_SESSION array
    $_SESSION = array();

    // Delete the session cookie by setting its expiration to an hour ago (3600)
    if (isset($_COOKIE[session_name()])) {      setcookie(session_name(), '', time() - 3600);    }

    // Destroy the session
    session_destroy();
  }

  // Delete the user ID and username cookies by setting their expirations to an hour ago (3600)
  setcookie('user_id', '', time() - 3600);
  setcookie('username', '', time() - 3600);

  // Redirect to the home page
  $home_url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . '/index.php';
  header('Location: ' . $home_url);
?>

登录该网站后，我无法注销.我真的需要用cookie登录吗?还是可以将其删除?

I cannot log out once logged in on the site. Do I really need cookie'd logins or can I take that out?

推荐答案

尝试一种更简单的方法，销毁所有会话cookie

Try a simpler approach, destroy all session cookies

session_start();
session_destroy();
$home_url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . '/index.php';
header('Location: ' . $home_url);
