【问题描述】：

我正在运行从 xml 数组中获取订单详细信息的脚本。问题是每次脚本运行时我都会遇到 foreach() 错误。我认为这是标题中的 htmlentities 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;

    }

数组是正确的我检查数组带来的所有数据没有空值。我在同一行收到 2 个错误 - foreach($xml->ListOrderItemsResult->OrderItems->OrderItem as $product)

试图获取非对象的属性

为 foreach() 提供的参数无效

XML

有人可以帮我吗？
如果您能提供实际的 XML，或者至少是其中的一部分，那就太好了。
已更新..请检查

标签： php arrays xml codeigniter foreach

【解决方案1】：

这应该可以工作，我用你的 xml 测试过

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

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

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

    }

}

可以有超过一组的订单项目，每个组可以包含多个项目。你也可以做这样的事情来测试

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

并且总是检查像

这样的 xml 结构

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

现在我只收到“为 foreach() 提供的参数无效”错误。
你试过第二个例子吗？在执行 foreach() 之前 - 尝试回显一些更简单的值作为检查以确保其他一切正常。
