cookies and CI4

Haven't looked at the code for set_cookie, so can't tell why that's not working.
But for setting the cookie with setCookie() you can do like this, so you can set multiple.

PHP Code:

public function myFunction()
{
    $this->request->setCookie([
        'name' => 'user4',
        'value' => 'value4',
        'expire' => time() + 6000
    ]);
    
    return $this->myFunctionOK($user);
}
