How to set Cookie in symfony?

// cookie getter
$string = $this->getRequest()->getCookie('mycookie');
 
// cookie setter
$this->getResponse()->setCookie('mycookie', $value);
 
// cookie setter with options
$this->getResponse()->setCookie('mycookie', $value, $expire, $path, $domain, $secure);

If you want to manipulate cookies outside of an action, you will need to access the Request and Answer objects without shortcut: 

$request  = sfContext::getInstance()->getRequest();

$response = sfContext::getInstance()->getResponse();

Cheers!
