[resolved] setcookie, more than one variable?

Hello all.
How would I go about setting another name-value pair within a cookie? I can't figure out the correct syntax. So far I have:

Code:

---

setcookie("user_id", '.$row->user_id.', time()+86400);

---

Any help is greatly appreciated.

why not just set a cookie array?

PHP Code:

---

<?php
// set the cookies
setcookie("cookie[three]", "cookiethree");
setcookie("cookie[two]", "cookietwo");
setcookie("cookie[one]", "cookieone");

// after the page reloads, print them out
if (isset($_COOKIE['cookie'])) {
   foreach ($_COOKIE['cookie'] as $name => $value) {
       echo "$name : $value <br />\n";
   }
}
?>

---

Thank you ALL.
