What are the implications of setting a cookie in a specific directory within a domain in PHP?

Setting a cookie in a specific directory within a domain in PHP can help control the scope of the cookie and limit its access to certain parts of the website. This can be useful for restricting access to sensitive information or for managing user preferences within a specific section of the site.

// Set a cookie with a specific path within the domain
setcookie("cookie_name", "cookie_value", time() + 3600, "/specific_directory", "example.com");
