How can the use of $_SERVER['HTTP_HOST'] and $_SERVER['REQUEST_URI'] simplify the process of determining the current domain in PHP?

To determine the current domain in PHP, we can use $_SERVER['HTTP_HOST'] to get the hostname of the current request and $_SERVER['REQUEST_URI'] to get the URI. By combining these two values, we can easily determine the current domain without having to parse the URL manually. 

$currentDomain = $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
echo $currentDomain;
