Question

我即将控制我的网页内容。所以我需要添加或删除会话/ cookie。我制作了一个工作正常的课程，但在cookie问题上，它不能正常工作。我在windows7中使用firefox 18和ubuntu 12.04 LTS进行了检查。使用

删除cookie

        setcookie(name, '', time()-9600) 



        foreach($this->_ck as $cookie)
        {

        $hrs=0;
            if($plus)
            {
        $hrs=3600*$cfg_cookie_time;
            }
            //setcookie('testcookie13', '', time()-3600*6);

        header("Set-Cookie: ".$cookie."=deleted; expires=Sun, 01-Jul-2012 08:59:12 GMT;");
        }

等...

我的课程是：

<?php

?>

你能帮忙吗？

Answer 1

我在您的代码中看到的一个错误是

    function _constract()

应该是

    function __construct()

Answer 2

setcookie($cookie_name, null, null);

无论如何都会删除cookie。在任何逻辑验证之前，在脚本开头的普通php中使用它。如果您正在使用此cookie并且您的cookie未被删除，那么您要么使用xml请求，要么您的逻辑中存在一些问题。祝你好运！

试一试：

    foreach($_cookie as $k => $kv)
        {

        return;
}


function add_cookie($_cookie)
{
        foreach($_cookie as $k => $kv)
        {
        setcookie($k, $kv, time()+3600*24*6);
