I am using to set cookie on user login

$a = setcookie($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');

But I can’t delete cookie

I tried

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]);

But I cant delete my cookie

If if I set secure cookie like this 

$a = setcookie($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);

I can delete but if user loged in domain.com and join to http://www.domain.com he was not login

or He loged in http://www.domain.com, he was not login domain.com

he was login http://www.domain.com or domain.com, i want to user login http://www.domain.com and domain.com

    I solved my problem, You can’t send header before you set cookie.

    I used ob_start() and that solved my problem
