Unset cookies php
提问by michael
I have this code that setted when login check is fine:
我在登录检查正常时设置了以下代码：
if((isset($_POST["remember_me"]))&&($_POST["remember_me"]==1))
{
setcookie('email', $username, time()+3600);
setcookie('pass', $pass, time()+3600);
}
Now, when I click on logout link (logout.php) i did this:
现在，当我点击注销链接（logout.php）时，我这样做了：
<?php session_start();
setcookie("email", '', 1, "");
setcookie("pass", '', 1, "");
$_SESSION["login"] = "";
header("location: aforum/enter_furom.php");
?>
I didn't use destroy session because I don't want to destroy all sessions.... now destroying a session is working fine... but when I try to unset cookies, the browsers (all browsers: explorer, chrome, firefox, mozilla) give me an error saying that the new cookies cant be setted...any help to unset the above cookies ?
我没有使用销毁会话，因为我不想销毁所有会话......现在销毁会话工作正常......但是当我尝试取消设置 cookie 时，浏览器（所有浏览器：资源管理器、chrome、firefox , mozilla) 给我一个错误，说无法设置新的 cookie......有什么帮助可以取消设置上述 cookie 吗？

either use the superglobal _COOKIEvariable:
要么使用超全局_COOKIE变量：
unset($_COOKIE['mycookiename']);
or call setcookie()with onlythe cookies name
或致电setcookie()与只有饼干名称
setcookie('mycookiename');
To reset your cookies at logout use:
要在注销时重置您的 cookie，请使用：
setcookie('pass');
setcookie('email');
For you login check:
对于您登录检查：
if(
isset($_POST["remember_me"]) &&
$_POST["remember_me"]==1 &&
$_COOKIE['pass'] != NULL &&
$_COOKIE['email'] != NULL &&
)

Check in your browser for the directory where the cookie operates. And unset it by specify the path the cookie have. Like in the example if the cookie directory is /aforum/
在您的浏览器中查看 cookie 运行的目录。并通过指定 cookie 的路径来取消设置。就像在示例中一样，如果 cookie 目录是/aforum/
setcookie ("email","",time()-1,"/aforum/","http:// yourdomain.com");

try this
尝试这个
setcookie ("email", "", time() - 3600);
setcookie ("pass", "", time() - 3600);
回答by Amit Merchant
Just set the value of cookie to falsein order to unset it,
只需将 cookie 的值设置false为以取消设置，
setcookie('cookiename', false);
That's the easiest way to do it.
这是最简单的方法。

To unset cookies in PHP, simply set their expiry time to a time in the past. For example:
要在 PHP 中取消设置 cookie，只需将它们的到期时间设置为过去的时间。例如：
$expire = time() - 300;
setcookie("email", '', $expire);
setcookie("pass", '', $expire);
回答by Martin
You need to set your expire time to the past, e.g.
您需要将过期时间设置为过去，例如
setcookie('email', '', time()-3600);
Also you should be using an Absolute URIfor your header('Location:' ....).
你也应该Absolute URI为你的header('Location:' ....).

In Chrome and IE8+ at least, the following will remove the cookie from the browser. It will not be reflected in the $_COOKIEarray until the page is reloaded however.
至少在 Chrome 和 IE8+ 中，以下内容将从浏览器中删除 cookie。但是，在$_COOKIE重新加载页面之前，它不会反映在数组中。
setcookie('cookiename','',0,'/',$cookieDomain)
setcookie('cookiename','',0,'/',$cookieDomain)
you may be able to leave off a few parameters here, but the important thing is you are setting an empty string, and that removes the cookie from the browser.
您可以在此处省略一些参数，但重要的是您正在设置一个空字符串，这会从浏览器中删除 cookie。
