为什么我无法在Firefox中创建Cookie？ [英] why can't I create cookies in Firefox?

问题描述

我无法创建具有以下行的Firefox Cookie：

I am not able to create a Firefox cookie with following line:

    setcookie("TestCookie", $value, time()+3600, "/", "localhost");

有人知道为什么吗？

已检查FF中的设置，并接受来自第三方的Cookie，并在过期时将其删除。

I have checked the settings in FF and it accepts cookies from 3rd parties and are deleted when they expire.

编辑：我现在可以使用此行：

I can create now with this line:

$domain = ($_SERVER['HTTP_HOST'] != 'localhost') ? $_SERVER['HTTP_HOST'] : false;
setcookie('cookiename', 'data', time()+60*60*24*365, '/', $domain, false);

但是如何删除？

我尝试只切换+到 - 但它没有工作。

I tried with just switching the + to - but it didn't work.

$domain = ($_SERVER['HTTP_HOST'] != 'localhost') ? $_SERVER['HTTP_HOST'] : false;
setcookie('cookiename', 'data', time()-60*60*24*365, '/', $domain, false);

推荐答案

自从我使用localhost cookies后，根据PHP手册中的注释，localhost是域参数的无效值。

It's been awhile since I worked with localhost cookies, but according to the comments in the PHP manual, 'localhost' is an invalid value for the domain parameter.

要在localhost上设置cookie，请使用 false 。示例：

To set a cookie on localhost, use false instead. Example:

setcookie("TestCookie", $value, time()+3600, "/", false);
