HTTP_*_VARS gone
Everywhere that you use any of the global variables of the form $HTTP_something_VARS, you will need to replace with $_something. The $HTTP global variables are no longer available.
| $HTTP_POST_VARS | $_POST |
|---|---|
| $HTTP_GET_VARS | $_GET |
| $HTTP_SERVER_VARS | $_SERVER |
| $HTTP_COOKIE_VARS | $_COOKIE |
You do not need to specify a “globals” line for any of the new underscore globals. They are automatically global and available to all functions.
