i am trying this code:

```
setcookie('email', $first_email, 'hash', $this->hash, 'logout', $this->log, time()+60*60*24*100);

```

but i got: `Warning: setcookie() expects parameter 3 to be long,`

I want `setcookie` with multiple variables. How can be done ? maybe an array ?

Then i will have something like this, that is compared with values in database

```
if(empty($_COOKIE['email']) || empty($_COOKIE['hash']) || empty($_COOKIE['logout'])) {
    //something
}
else
//db

```
