I'm trying to get this to work, but I'm doing something wrong? Please help...
$getFunction = urlencode($_GET['ga']); function $getFunction(){ include("functions/function.".$getFunction.".php"); }
http://www.php.net/manual/en/functions.variable-functions.php
if(isset($_GET['ga']) and ctype_alnum($_GET['ga'])) { if(file_exists('functions/function.'.$_GET['ga'].'.php')) { include('functions/function.'.$_GET['ga'].'.php'); } else { die("File does not exist"); } }
