Php XML数组-尝试获取非对象foreach（）的属性错误-Codeigniter

我正在运行从xml数组中获取订单详细信息的scrip。问题是每次脚本运行时都会出现foreach（）错误。我很高兴这是一个在标题上的问题，但不确定。你能帮忙吗

$products='';

$xml=simplexml_load_string($response);

$temp_arr=array();
foreach($xml->ListOrderItemsResult->OrderItems->OrderItem as $product)
    {
    $temp_arr[]=array('item'=>(string)$product->Title,'quantity'=>(string)$product->QuantityOrdered,'order_item_code'=>(string)$product->OrderItemId,'sku'=>(string)$product->SellerSKU);
    }
return $temp_arr;

    }

数组是否正确我正在检查数组中的所有数据是否存在空值。 我在同一行中遇到2个错误-

foreach（$xml->ListOrderItemsResult->OrderItems->OrderItems as$product）

正在尝试获取非对象的属性

为foreach（）提供的参数无效

XML

我用你的xml测试了一下，这应该行得通

foreach ($xml->ListOrderItemsResult->OrderItems as $items) {

    foreach( $items->OrderItem as $orderitem ){

        echo 'test id is' . $orderitem->OrderItemId ; 

    }

}

可以有多个订单项目组，每组可以包含多个项目。您也可以这样做来进行测试

echo $xml->ListOrderItemsResult->OrderItems->OrderItem[0]->OrderItemId ; 

并始终检查xml结构，如

    echo '<pre>' ; 
    print_r($xml);
   echo '</pre>' ; 

echo'；
            <?php
        $xml = '<?xml version="1.0"?>

打印（xml）；
回声'；

这对我很有用

有人能帮我吗？如果你能提供实际的XML，或者至少是其中的一部分，那就太好了。更新。。请检查我现在只收到“为foreach（）提供的参数无效”错误。您是否尝试了第二个示例？在执行foreach（）之前——尝试回显一些简单的值，以确保其他所有内容都正常工作。
