What is the difference between handling cookies in PHP 4.xx and PHP 5.0?

In PHP 4.xx, cookies were handled using the setcookie() function with a different syntax compared to PHP 5.0. In PHP 5.0, the setcookie() function had a new parameter for setting the cookie's expiration time. To handle cookies in PHP 5.0, you need to adjust the syntax of the setcookie() function to include the expiration time parameter. 

// PHP 4.xx syntax for setting a cookie
setcookie("cookie_name", "cookie_value", time() + 3600);

// PHP 5.0 syntax for setting a cookie with expiration time
setcookie("cookie_name", "cookie_value", time() + 3600, "/");
