我正在尝试使用 PHP 在 xml 以上提取,我尝试使用以下代码

$xml_response="my xml contents";
$xml = simplexml_load_string($xml_response);
echo $xml->person[0]['headers'] . "<br>";
echo $xml->id;

我可以得到 id 但我不能得到其他东西

echo $xml->first-name; 

它显示错误,因为 -firstname 之间,然后我有很多类别,比如人物详细信息,我如何创建循环来检索?

要更正已解析的遍历 XML,您必须将其视为对象。举几个例子:

$xml = simplexml_load_string($xml);
echo $xml->id . PHP_EOL;
echo $xml->educations->education[0]->{'school-name'} . PHP_EOL;
echo $xml->educations->education[0]->{'end-date'}->year . PHP_EOL;

注:

作为 <something-with-something> 的标签必须由 {'something-with-something'} 表达式正确处理。


如果你想迭代节点(这里education):

foreach($xml->educations->education as $item) {
    echo $item->{'school-name'} . PHP_EOL;
    echo $item->degree . PHP_EOL;
}
