How can PHP superglobals like $_SERVER be utilized to dynamically retrieve folder names during runtime?

To dynamically retrieve folder names during runtime using PHP superglobals like $_SERVER, you can utilize the $_SERVER['REQUEST_URI'] variable to get the current URL path. Then, you can manipulate this path to extract the folder names. This can be useful for building dynamic file paths or determining the current folder structure in a web application. 

$currentPath = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);
$folders = explode('/', $currentPath);

foreach($folders as $folder) {
    echo $folder . '<br>';
}
