Actually, although suppressing the E_NOTICE, this is not exactly the behavior you want.
What if $_GET['Does']['Not']['Exist'] really doesn't exists? It is then created and assigned to $param when passed as an argument to the param function. Therefore polluting $_GET with another unused array and array element, creating more internal hashes for no reason. Try that with 50 form vars and you be creating 50 more variables that really never even existed. Maybe not much of a foot print but very unnecessary. There are probably many different ways you can implement this functionality at a user-level, try the php.general list.
