将PHP数组转换为XML丢失键

Question

我对xml不好，所以我需要一些帮助。这是我想用来转换为xml输出的数组。

    Array
(
    [invoices] => Array
        (
            [0] => Array
                (

我在How to convert array to SimpleXML中使用了Hanmant的答案，但我得到的输出是：

这是我的代码：

$xml = null;
    foreach($input['invoices'] as $invoice) {
        $xml_data = new SimpleXMLElement('<?xml version="1.0"?><data></data>');
        array_to_xml($invoice, $xml_data);
        $xml = $xml_data->asXML();
    }
print_r($xml);

正如您所看到的那样，输出丢失了密钥并且聚集在一起。我做错了什么？

尝试使用下面的代码，您尝试将XML打印为数组所在的位置。您想将XML输出到页面。

$xml = null;
foreach($input['invoices'] as $invoice) {
    $xml_data = new SimpleXMLElement('<?xml version="1.0"?><data></data>');
    array_to_xml($invoice, $xml_data);
    $xml = $xml_data->asXML();
}
echo $xml;

您需要查看页面的来源，否则浏览器可能会像解析HTML一样解析XML。
