What role does the base_url function play in PHP projects?

The base_url function in PHP projects is used to dynamically generate the base URL of the website. This is useful for creating links, redirects, or including assets like CSS or JavaScript files in a way that is independent of the current URL. By using the base_url function, you can ensure that your links and assets will work correctly even if the website's URL structure changes. 

function base_url() {
    $protocol = isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http";
    $host = $_SERVER['HTTP_HOST'];
    return $protocol . "://" . $host;
}

echo base_url();
