file_get_html weird output

file_get_html weird output

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.
