What are the recommended methods for handling nested directories when duplicating folders using FTP in PHP?

When duplicating folders using FTP in PHP, it is important to handle nested directories properly to ensure that all subdirectories and files are copied over correctly. One recommended method is to use recursive functions to traverse through the directory structure and copy each file and subdirectory. 

function duplicateFolder($source, $destination){
    $dir = opendir($source);
    @mkdir($destination);
    
    while(false !== ($file = readdir($dir))){
        if(($file != '.') && ($file != '..')){
            if(is_dir($source . '/' . $file)){
                duplicateFolder($source . '/' . $file, $destination . '/' . $file);
            } else {
                copy($source . '/' . $file, $destination . '/' . $file);
            }
        }
    }
    
    closedir($dir);
}

// Usage
$sourceFolder = '/path/to/source/folder';
$destinationFolder = '/path/to/destination/folder';
duplicateFolder($sourceFolder, $destinationFolder);
