How do you set a php cookie with multiple values?

Question

I want to create a php cookie that stores the username and the userid. Or is it better to just use one to get the other?

Answer 1

If you're only looking to store two values, it may just be easier to concatenate them and store it as such:

setcookie("acookie", $username . "," . $userid);

And to retrieve the information later,

if(isset($_COOKIE["acookie"])){
    $pieces = explode(",", $_COOKIE["acookie"]);
    $username = $pieces[0];
    $userid = $pieces[1];
}
