Are there any common pitfalls to avoid when setting cookies in PHP?

One common pitfall to avoid when setting cookies in PHP is not using the correct syntax for setting the expiration time. It is important to set the expiration time correctly to ensure that the cookie is stored for the desired duration. Additionally, make sure to set the path parameter to specify the directory where the cookie is available.

// Set a cookie with an expiration time of 1 hour and available in the root directory
setcookie("cookie_name", "cookie_value", time() + 3600, "/");
