我正在创建具有 n 级别类别的选择框，但我得到空白记录我没有发现错误是什么问题。

$value = 'upload_files/';
echo $manage_folder->getFolderOptionListByParentId(0,$value);

function getFolderOptionListByParentId($parent = 0,$value)
{
        $html = '';
        $query = mysql_query("SELECT * from tbl_folder where folder_parent_id = '$parent'");
        if($query){
            while($row = mysql_fetch_assoc($query))
            {
                $current_id = $row['folder_id'];
                $passvalue =  $value.$row['folder_name'].'/';
                $html .= '<option value="'.$passvalue.'">' . $value.$row['folder_name'].'/<option>';
                $has_sub = NULL;
                $has_sub = mysql_fetch_assoc(mysql_query("SELECT COUNT(folder_parent_id) as total FROM tbl_folder WHERE folder_parent_id = '$current_id'"));
                if($has_sub['total'] != 0){
                    $html.= $this->getFolderOptionListByParentId($current_id,$passvalue);
                }

            }
        }

        return $html;
    }

我得到的答案如下
