Use of undefined constant REQUEST_URI

[hellkaim]

Dear Christopher.
There is an issue with PHP 7.0+ and the code in update.php

The one here is "REQUEST_URI". In PHP 7.0+ the constant has to be defined (as I understood) before it can be used, while with PHP 5.0+ it's not that mandatory.

Please change all occurrences of REQUEST_URI to 'REQUEST_URI' to solve the issue.

Thanks!
