}
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $Url);

Here is some sample code (XML parsing module may not be available on your PHP installation):
下面是一些示例代码（XML 解析模块可能在您的 PHP 安装中不可用）：
<?php
$url="http://www.arrowcast.net/fids/mco/fids.asp?sort=city&city=&number=&airline=&adi=A";
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url); // get the url contents
$data = curl_exec($ch); // execute curl request
curl_close($ch);
$xml = simplexml_load_string($data);
print_r($xml)
?>
The variable $xmlnow is a multi-dimensional key value array and you should easily be able to figure out how to get the elements from there.
该变量$xml现在是一个多维键值数组，您应该很容易弄清楚如何从那里获取元素。

URLConnection con=url.openConnection();
int x=0;

// the SAX way:
XMLReader myReader = XMLReaderFactory.createXMLReader();
myReader.setContentHandler(handler);
myReader.parse(new InputSource(new URL(url).openStream()));
// or if you prefer DOM:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new URL(url).openStream());
