如何在Netsuite PHP工具包中创建新的AssemblyItem？

require_once 'NetsuiteService.php';

// 创建Netsuite服务对象
$service = new NetSuiteService();

// 创建一个新的AssemblyItem对象
$assemblyItem = new AssemblyItem();
$assemblyItem->name = "My AssemblyItem";
$assemblyItem->description = "This is a new AssemblyItem created using Netsuite PHP toolkit";
$assemblyItem->price = 100.00;

// 添加组件
$component1 = new AssemblyComponent();
$component1->item = new RecordRef();
$component1->item->internalId = 123; // 组件的内部ID
$component1->quantity = 2;

$assemblyItem->componentList = new AssemblyComponentList();
$assemblyItem->componentList->component = array($component1);

// 设置其他属性
$assemblyItem->unit = new RecordRef();
$assemblyItem->unit->internalId = 1; // 单位的内部ID

// 保存AssemblyItem
$response = $service->add($assemblyItem);

// 检查保存结果
if (!$response->writeResponse->status->isSuccess) {
    echo "创建AssemblyItem失败：" . $response->writeResponse->status->statusDetail[0]->message;
} else {
    echo "创建AssemblyItem成功，ID：" . $response->writeResponse->baseRef->internalId;
}
