Php 无法删除 cookie（安全 Cookie）

Question

我用来在用户登录时设置 cookie

$a = setcookie($this->remCookieName,$cookie, time() + $this->remTime, '/', 'domain.com');
$b = setcookie($this->remCookieName,$cookie, time() + $this->remTime, '/', 'www.domain.com');
$c = setcookie($this->remCookieName,$cookie, time() + $this->remTime, '/', '.domain.com');

但是我不能删除cookie

我试过了

setcookie($this->remCookieName,'', mktime(12,0,0,1, 1, 1990), '/', '.domain.com',true);
setcookie($this->remCookieName,'', mktime(12,0,0,1, 1, 1990), '/', 'domain.com',true);
setcookie($this->remCookieName,'', mktime(12,0,0,1, 1, 1990), '/', 'www.domain.com',true);
setcookie($this->remCookieName,'',mktime(12,0,0,1, 1, 1990), '/', 'test.domain.com',true);
setcookie($this->remCookieName,'',mktime(12,0,0,1, 1, 1990), '/', '.www.domain.com',true);

setcookie($this->remCookieName,'', mktime(12,0,0,1, 1, 1990), '/', '.domain.com',false);
setcookie($this->remCookieName,'', mktime(12,0,0,1, 1, 1990), '/', 'domain.com',false);
setcookie($this->remCookieName,'', mktime(12,0,0,1, 1, 1990), '/', 'www.domain.com',false);
setcookie($this->remCookieName,'', mktime(12,0,0,1, 1, 1990), '/', 'test.domain.com',false);
setcookie($this->remCookieName,'',mktime(12,0,0,1, 1, 1990), '/', '.www.domain.com',false);


setcookie($this->remCookieName,'', mktime(12,0,0,1, 1, 1990), '/', '.domain.com');
setcookie($this->remCookieName,'', mktime(12,0,0,1, 1, 1990), '/', 'domain.com');
setcookie($this->remCookieName,'', mktime(12,0,0,1, 1, 1990), '/', 'www.domain.com');
setcookie($this->remCookieName,'', mktime(12,0,0,1, 1, 1990), '/', 'test.domain.com');
setcookie($this->remCookieName,'',mktime(12,0,0,1, 1, 1990), '/', '.www.domain.com');

setcookie($this->remCookieName,'', mktime(12,0,0,1, 1, 1990));

setcookie($this->remCookieName,NULL,mktime(12,0,0,1, 1, 1990));

unset($_COOKIE[$this->remCookieName]);

但我不能删除我的 cookie

如果我像这样设置安全cookie

$a = setcookie($this->remCookieName,$cookie, time() + $this->remTime, '/', 'domain.com',TRUE);
$b = setcookie($this->remCookieName,$cookie, time() + $this->remTime, '/', 'www.domain.com',TRUE);
$c = setcookie($this->remCookieName,$cookie, time() + $this->remTime, '/', '.domain.com',TRUE);

我可以删除，但如果用户登录 domain.com 并加入 www.domain.com 他没有登录

或者他登录了www.domain.com，他没有登录域。com

他登录 www.domain.com 或 domain.com，我想用户登录 www.domain.com 和 domain.Z4D2366D9A2DDA102C4D2366D9A2D14BEC

对不起我的英语:)

Answer 1

我解决了我的问题，你不能在设置 cookie 之前发送 header。

我使用了 ob_start() 并解决了我的问题
