如何在php中删除我网站的所有cookie

问题描述

我想知道是否可以在用户单击注销时删除我网站的所有 cookie，因为我使用它作为删除 cookie 的功能，但它无法正常工作:

I'm wondering if I can delete all my website's cookies when a user click on logout, because I used this as function to delete cookies but it isn't work properly:

setcookie("user",false);

有没有办法在 PHP 中删除一个域的 cookie?

Is there a way to delete one domain's cookies in PHP?

推荐答案

PHP setcookie()

取自该页面，这将取消您域的所有 cookie:

Taken from that page, this will unset all of the cookies for your domain:

// unset cookies
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, '/');
    }
}
