How can the $_SERVER['HTTP_HOST'] variable be utilized to access the subdomain?

To access the subdomain using the $_SERVER['HTTP_HOST'] variable, you can extract the subdomain by splitting the host name using the dot as a delimiter. This allows you to isolate the subdomain part of the host name and use it as needed in your code. 

$host = $_SERVER['HTTP_HOST'];
$subdomain = explode('.', $host)[0];

echo "Subdomain: " . $subdomain;
