几天来，我一直在尝试解决此问题，但仍然无法解决问题所在。为什么不加载此XML文件的任何想法？我不断收到“ XML属性不可用或为空”消息。
true我也尝试添加这样的名称空间，但无济于事：
$xml = simplexml_load_file('https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml');
if(!isset($xml->Cube->Cube) || empty($xml->Cube->Cube)){
echo 'XML attribute not available or empty';
}
我必须承认，PHP不是我的事。
感谢您的帮助。

请尝试以下代码：
$file = 'https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml';
function simplexml_load_file_curl($url) {
$xml="";
if(in_array('curl', get_loaded_extensions())){
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$xml = simplexml_load_string(curl_exec($ch));
curl_close($ch);
}
else{
$xml = simplexml_load_file($url);
}
return $xml;
}
$xml = simplexml_load_file_curl($file);
echo '<pre>';print_r($xml);echo '</pre>';
输出：
