The number of ways of reading an xml file from another server in PHP?

$url =  urldecode( $object_list_url );
 $xmlstr = file_get_contents ( $url );
 $obj = new SimpleXMLElement ( $xmlstr, LIBXML_NOCDATA );

$c = curl_init($url);
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
$xmlstr = curl_exec($c);

var_dump(ini_get('allow_url_fopen'));

<?php
phpinfo();
?>
