สอบถามการเขียนเก็บค่าลงใน Array ระหว่าง C# กับ PHP ครับ

public class PersonalData
{
    public string FirstName{ set; get; }
    public string LastName { set; get; }
}

List<PersonalData> list = new List<PersonalData>();

while(dtReader.Read())
{
	list.Add(New PersonalData { FirstName = dtReader["xxx"], LastName = dtReader["yyyy"]});
}

foreach(PersonalData item in list)
{
	// item.FirstName
	// item.LastName
}

function getNode($id) {
        $query = "SELECT * FROM mmnu WHERE id_parent = '$id'";
        $result = mysql_query($query);
        $node = array();
        if($result) {
            while($row = mysql_fetch_array($result)) {
                $node[] = array("title"=> $row['name_th'], "folder" => true, "children"=> $this->getNode($row['id_mmnu']));
            }
        }
        return $node;
    }

public class PersonalData
{
    public string FirstName{ set; get; }
    public string LastName { set; get; }
}

public List<PersonalData> getData()
{
	List<PersonalData> list = new List<PersonalData>();

	while(dtReader.Read())
	{
		list.Add(New PersonalData { FirstName = dtReader["xxx"], LastName = dtReader["yyyy"]});
	}

	return list;
}



var newList = getData();
