在远程php网站上显示wordpress帖子

Question

Hello i have wordpress website i have around 100 post in it and i daily update them

i want to display latest 3 post on remote website is this possible with any rss feed parsing or any other method.I tried with below code but it shows failed

<?php 
        $feedUrl = 'http://testserver.com/brand_new/feed';
        $rawFeed = file_get_contents($feedUrl);

        print_r($rawFeed);
        exit;

         $anobii = new SimpleXmlElement($rawFeed);

        foreach ($anobii->channel->item as $anobiiinfo):
            $title=$anobiiinfo->title;
            $desc=$anobiiinfo->description;       
            echo "<span> ",$title,"</span> <br/> <span> ",$desc,"</span>";
        endforeach;
    ?>

I tried even with

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'http://wallpapers.celeborama.net/feed/');
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $data = curl_exec($ch);
    curl_close($ch);

$xml = new SimpleXMLElement($data);

but it shows error as well

Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in G:\xampp\htdocs\wpfeed.php:11 Stack trace: #0 G:\xampp\htdocs\wpfeed.php(11): SimpleXMLElement->__construct('') #1 {main} thrown in G:\xampp\htdocs\wpfeed.php on line 11

Wordpress provide function to fetch remote data. So you can use that.see below code

$feedUrl = 'http://project.demotestserver.com/brand_new/feed';
$data = wp_remote_retrieve_body(wp_remote_get($feedUrl, array( 'timeout' => 30000 ) ));
$dom = new DOMDocument;
$dom->loadXML($data);
if (!$dom) {
    echo 'Error while parsing the document';
    exit;
}
$xml = simplexml_import_dom($dom);
$posts = $xml->channel->item;
    $i=0;
    foreach($posts as $key => $post) {
       if($i>=3) continue;
        $title=$post->title;
        $i++;

    }

   print_r($title);
