Php可以'；t删除cookie（安全cookie）

我正在使用设置用户登录时的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]);

但是我不能删除我的饼干

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，他就没有登录

或者他登录了www.domain.com，他没有登录domain.com

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

对不起，我的英语：）

我解决了我的问题，在设置cookie之前，您不能发送标题

我使用ob_start（）解决了我的问题

当我创建任何子域或根域时，我可以访问任何子域或根域，但不能删除

$c=setcookie（$this->remcokieename，$cookie，time（）+$this->remTime，'/'，'.domain.com'）

但是当我设置cookie secure set=TRUE

$c=setcookie（$this->remcokieename，$cookie，time（）+$this->remTime，'/'，'.domain.com'，TRUE）我可以删除，但无法访问任何子域。我希望我的cookie可以访问任何子域或根域，我想删除：）我解决了我的问题，您必须在设置cookie之前没有发送头：）我使用了ob_start（）并解决了我的问题请在下面添加您的解决方案作为答案。
