Read xml data from url using curl and php - php

Question

I want to read XML data from a URL. I have the URL as follows:
http://www.arrowcast.net/fids/mco/fids.asp?sort=city&city=&number=&airline=&adi=A
Here is my code:
$Url="http://www.arrowcast.net/fids/mco/fids.asp?sort=city&city=&number=&airline=&adi=A";
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $Url);
$output = curl_exec($ch);
$resultCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
// Close the cURL resource, and free system resources
curl_close($ch);
Could anyone please tell me how to read xml data?

Answer 1

Here is some sample code (XML parsing module may not be available on your PHP installation):
<?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 $xml now is a multi-dimensional key value array and you should easily be able to figure out how to get the elements from there.

// 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());

$yt_vids[$count]['title'] = $v['title'];
$count++;
}
}

$yt_vids[$count]['id']=str_replace('http://www.youtube.com/watch?v=', '', $youtube['entry']['link']['#attributes']['href']);
$yt_vids[$count]['title']=$youtube['title'];
}
echo "<pre>";
print_r($yt_vids);
