Is the below reasonable safe ?
I have all of my main functions outside the web folder
I am including this function with every php script that

function getBrain()

$temp = explode('.', $_SERVER['SERVER_NAME']);
Because $_SERVER['SERVER_NAME'] can be manipulated by the user in some cases, you must consider $temp tainted at this point.
$size = count($temp);
$server = $temp[$size -2];
Now $server is tainted.
Therefore, this is a security vulnerability. Hope that helps. Chris -- Chris Shiflett Brain Bulb, The PHP Consultancy http://brainbulb.com/$brainPath = "/home/".$server."/includes/fonovisa.inc";
