Found something on using your script with vbulletin.
HERE
So it looks like the island should look something like:
Code
/* PHP CODE HERE */
if (@include(getenv('DOCUMENT_ROOT').'/phpadsnew/phpadsnew.inc.php')) {
if (!isset($phpAds_context)) $phpAds_context = array();
$phpAds_raw = view_raw ('zone:13', 0, '', '', '0', $phpAds_context);
}


/* BODY HERE */
$body = <<<EOF
$phpAds_raw[html]
EOF;
