Question

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

You cannot assign 3 different cookies in one function call. You need to set each cookie individually, as can be seen below:

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