I've attached an updated patch with the following changes:

- return an empty string instead of throwing an exception if the
extension is not installed
- drop the $GLOBAL (it wasn't actually necessary)

The function still throws an exception if $key is empty because this can
only happen if the function is called with a wrong parameter (which is a
coding error which the developer should be made aware of).
