How can PHP be used to recursively delete files and empty folders within a directory structure?

To recursively delete files and empty folders within a directory structure using PHP, you can use a combination of recursive functions to traverse the directory tree and delete the files and folders accordingly. You can use PHP's `unlink()` function to delete files and `rmdir()` function to delete folders. Remember to handle permissions and error checking to ensure the deletion process goes smoothly. 

function deleteFiles($dir) {
    foreach(glob($dir . '/*') as $file) {
        if(is_dir($file)) {
            deleteFiles($file);
            rmdir($file);
        } else {
            unlink($file);
        }
    }
}

$directory = 'path/to/directory';
deleteFiles($directory);
