file_get_html奇怪的输出

I've written a very small piece of code as you can see below.

<?php
include_once 'simple_html_dom.php';

$url = "http://passenger.cm.be/nl/contactpoints/723?service-1057";

$html = file_get_html($url);

echo $html;
?>

When I run this code on my wamp homeserver, it is showing the webpage as it should. However, when I upload it to my online server I'm getting the result below:

I have absolutely no idea what this is and why it is showing like this. Has anyone else experienced this problem before and know a solution?

Thanks in advance.

This is a hint for you, clearly says that you should NOT grab and parse raw HTML but use civilized APIs instead.

Use cURL instead to download the web page...

Here's a function I use for that purpose:

function dlPage($href) {

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_HEADER, false);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_URL, $href);
    curl_setopt($curl, CURLOPT_REFERER, $href);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    $str = curl_exec($curl);
    curl_close($curl);

    return $str;
}

Then you load the content this way:

$url = "http://passenger.cm.be/nl/contactpoints/723?service-1057";

// Create a DOM object & load HTML from a URL 
$html = new simple_html_dom();

// Load HTML from a string
$html->load(dlPage($url));

echo $html;

And be sure you have the php cURL module activated...
