Question

我遇到了会话cookie的问题，我试图在会员注销时删除所有cookie，但我似乎无法让它工作。这是我目前在logout.php

中的内容

<?php 
session_start();
if( session_unregister('loginid') == true && session_unregister('username')==true ) {
if (isset($_SERVER['HTTP_COOKIE'])) {
    $cookies = explode(';', $_SERVER['HTTP_COOKIE']);
    foreach($cookies as $cookie) {
        $parts = explode('=', $cookie);
        $name = trim($parts[0]);
        setcookie($name, '', time()-1000);
        setcookie($name, '', time()-1000, '/');
    }
}
    session_destroy();
    header('Location: login.php');
  } else {
   unset($_SESSION['loginid']);
   unset($_SESSION['username']);
   session_destroy();
   header('Location: login.php');
}
?>

如果有人能为我发光，那将是非常感激的。谢谢

Answer 1

你可以试试这个

session_start();
 if (isset($_COOKIE['cookie1'])) {
unset($_COOKIE['hi']);
session_destroy();
unset($_COOKIE['test1']);
setcookie('hi', null, -1, '/');
setcookie('test1', null, -1, '/');
header('Location:login.php');
return true;
exit;
} else {
return false;
}

这是我登录部分的所有代码。

<?
unset($login,$pwrd,$id);
session_start();
session_register("login","pwrd","id");

if($logout==1){
    session_destroy();
    header("Location: ".$PHP_SELF);
}

require('config_inc.php');
require('error_inc.php');

    global $t_user;
    $query = "select id from ".$t_user." where email=\"".$log."\" and pass=\"".$pass."\" ";      
    $result = MYSQL_QUERY($query);
    if(mysql_num_rows($result)>0){
        $id=mysql_result($result,0,"id");
        @mysql_free_result($result);  
        return $id;
    }else{
