You probably want this:

PHP Code:

require_once(DIR . '/includes/class_vurl.php');

$vurl = new vB_vURL($vbulletin);
$something = $vurl->fetch_body($vbulletin->options['mod_hello_active'], 0, false, false); 


Otherwise you rely on allow_url_fopen being on, which is not necessarly the case.
Also, reading a file into an array and imploding it afterwards seems rather unnecessary overhead -> file_get_contents().
