        if (!file_exists($dirname)) {
    
            return false;
        }
        // Is a file to delete 
        if (is_file($dirname) || is_link($dirname)) {
    
            return unlink($dirname);
        }
        // Start reading directory 
        $dir = dir($dirname);
        if ($dir) {
    
            while (false !== $entry = $dir->read()) {
    
                if ($entry == '.' || $entry == '..') {
    
                    continue;
                }
                // Delete the file 
                do_rmdir($dirname . '/' . $entry);
            }
        }
        // Close directory 
        $dir->close();
        // Whether to delete its own folder
