Immediate remove cookie data in zend-mvc application

Posted in Tutorial PHP, Zend Framework, Zend Framework 2, Zend Framework 3 by samsonasik on August 8, 2019

In zend-mvc application, we can utilize Zend\Http\Header\SetCookie header to set cookie to be added to response header. For example, we have a setAction() to set it, we can do:

use Zend\Http\Header\SetCookie;
// ...
    public function setAction()
    {
        $request  = $this->getRequest();
        $response = $this->getResponse();

        $response->getHeaders()->addHeader(new SetCookie(
            // name
            'test',

            // value
            'abc',
            
            // expires
            \time() + (60 * 60 * 24 * 365),
            
            // path
            '/',
            
            // domain
            null,
            
            // secure
            $request->getUri()->getScheme() === 'https',
            
            // httponly
            true
        ));

        return $response;
    }
// ...

Above, we set cookie with name “test” with value “abc”, with expires 1 year. To remove it completely before 1 year hit, we can pass 8th parameter as maxAge to be 0, so, for example, we have a removeAction to remove it, we can do:

use Zend\Http\Header\SetCookie;
// ...
    public function removeAction()
    {
        $request  = $this->getRequest();
        $response = $this->getResponse();

        $cookie   = $request->getCookie();
        if (! isset($cookie['test'])) {
            // already removed, return response early
            return $response;
        }

        $response->getHeaders()->addHeader(new SetCookie(
            'test',
            null, // no need to set value
            null, // no need to set expires
            '/',
            null,
            $request->getUri()->getScheme() === 'https',
            true,
            0    // set maxAge to 0 make "test" cookie gone
        ));

        return $response;
    }
// ...

That’s it!
