php中发票合并quickbook sdk中的总税额

我正在使用用于php的ConsoleByte Quickbook在线版本。 我正在创建发票，它对我来说运行良好。 而且我要把税包括在内。但我必须取消这项税收，并希望增加总税收。 谁能帮帮我吗

一切都很好，我只想添加附加图像相同的税。 请帮忙 提前谢谢

添加发票的我的代码：

公共函数addInvoice（$invoiceArray、$chargeArray、$customerRef、$db_product、$invoice_id、$other_charges、$price_grid、$payment、$orderId、$quickbook_id、$display_order_id、$payment_terms_name、$payment_terms_day）{

     $IPP = new \QuickBooks_IPP($this->QBO_DSN);

    // Get our OAuth credentials from the database
    $creds = $this->IntuitAnywhere->load(Session::get('useremail'), Session::get('user_id'));
    // Tell the framework to load some data from the OAuth store
    $IPP->authMode(
        \QuickBooks_IPP::AUTHMODE_OAUTH,
        Session::get('useremail'),
        $creds);

    if ($this->is_sandbox) {
        // Turn on sandbox mode/URLs
        $IPP->sandbox(true);
    }
    // This is our current realm
    $this->realm = $creds['qb_realm'];

    // Load the OAuth information from the database
    $this->context = $IPP->context();


    $InvoiceService = new \QuickBooks_IPP_Service_Invoice();


    if($quickbook_id > 0) {
