When I ran this is firefox as

Code:

<html>
  <head>
    <title></title>
    <meta content="">
    <style></style>
  </head>
  <body>

<?php 
 if(isset($_COOKIE['cart_id'])) { 
     $cart_id = $_COOKIE['cart_id']; 
	  } else { 
     $cart_id = md5(uniqid(rand())); 
     setcookie("cart_id", $cart_id, time() + 3600); 
}

echo ($_COOKIE['cart_id']); ?>

</body>
</html>

I got an error form firefox saying the headers had already been set and thus the cookie couldn't be added. But after changing it to

Code:

<?php 
 if(isset($_COOKIE['cart_id'])) { 
     $cart_id = $_COOKIE['cart_id']; 
	  } else { 
     $cart_id = md5(uniqid(rand())); 
     setcookie("cart_id", $cart_id, time() + 3600); 
}
<html>
  <head>
    <title></title>
    <meta content="">
    <style></style>
  </head>
  <body>

<?PHP
echo ($_COOKIE['cart_id']); ?>

</body>
</html>

It worked fine.
