What are some best practices for ensuring the proper functioning of cookies in PHP, especially when dealing with discrepancies in how different browsers display cookie values?

When dealing with discrepancies in how different browsers display cookie values in PHP, a best practice is to set the cookie's path and domain to ensure consistent behavior across browsers. This can be achieved by explicitly setting these parameters when creating the cookie using the setcookie() function. 

// Set cookie with explicit path and domain
setcookie("cookie_name", "cookie_value", time() + 3600, "/", "example.com");

// Retrieve cookie value
$cookie_value = $_COOKIE['cookie_name'];

// Use the cookie value as needed
echo $cookie_value;
