Question

I have a small problem with a script that reads an XML file and prints the output:

<?php

  $doc = new DOMDocument();
  $doc->load("http://www.tripadvisor.it/Feeds-d235955-treviews.xml");
  foreach ($doc->getElementsByTagName('item') as $node) {
      echo $node->getElementsByTagName('title')->item(0)->nodeValue;
      echo $node->getElementsByTagName('description')->item(0)->nodeValue;
      echo $node->getElementsByTagName('link')->item(0)->nodeValue;
      echo $node->getElementsByTagName('pubDate')->item(0)->nodeValue;
  }

?> 

If you use this script on my personal domain (hosting) it works fine, but if I use on my VPS does not work and returns these errors:

Warning: DOMDocument::load(http://www.tripadvisor.it/Feeds-d235955-treviews.xml) [domdocument.load]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found in /home/AAA/public_html/test.php on line 4
Warning: DOMDocument::load() [domdocument.load]: I/O warning : failed to load external entity "http://www.tripadvisor.it/Feeds-d235955-treviews.xml" in /home/AAA/public_html/test.php on line 4

Which PHP or APACHE settings that may cause problems?

As file_get_contents is not working in your server so try to use use curl to connect with tripadvisor server as below

<?php
$init = curl_init();
curl_setopt($init, CURLOPT_URL,'http://www.tripadvisor.it/Feeds-d235955-treviews.xml');
curl_setopt($init, CURLOPT_RETURNTRANSFER, 1);
$contents = curl_exec ($init);
curl_close ($init);
$xml = simplexml_load_string($contents);
print"<pre>";
print_r($xml);
?>
