global variabe PHP
developer PHP:
"Global variables are no longer registered for input data (POST, GET, cookies, environment and other server variables). Instead of using $foo, you must use or you can use $_REQUEST["foo"] (includes any variable that arrives through the request, namely, POST, GET and cookie variables), or use one of the specific $_GET["foo"], $_POST["foo"], $_COOKIE["foo"] or $_FILES["foo"], depending on where the input originates. Also, you can look at the import_request_variables() function.
Note that register_globals is going to be depracated (i.e., turned off by default) in the next version of PHP, because it often leads to security bugs.
Read http://php.net/manual/en/security.registerglobals.php for further information."
