How do I add php code to my forum?

[thebwit]

Ok I have figured out where I want to place the code after going through all the templates. The code basically just pulls data from a db that is not part of the vbulletin and I need to show it. I searched for ob_start(); but that just said to use a widget and I am not using the vb cms just the bb.

So the question is, inside a specific template, how do I add code such as:

<?php
$sql = "select items from table";
$mm = mysql_query($sql);
while ($ms = mysql_fetch_array($mm)) {
echo "WHAT I WANT ECHOED";
}
?>

Thanks in advance.
