register globals changed to off, script breaks

I had a couple pages that had used a few 'a href' links to create a URL like this: http://mydomain.com/profile.php?cid=6 When you clicked the link, it went to the profile.php page, which had the following code snippet: foreach($_GET as $varname => $value) $formVars[$varname] = trim($value); This worked great when the server had 'register globals' set to on. However, desiring to tighten up the security of the server a bit, I turned register globals to off. Now the above code snippet doesn't work. I've done quite a bit of searching and reading and haven't yet come up with a similar substitute (and I'm still learning PHP) for creating the variable array from the GET. What does work is: $cid = $_GET($varname); But that is only for when a single variable is passed, not when a bunch of them get passed and need to be put into an array. Would appreciate any tips. Thanks Kevin
