$_POST instead of $HTTP_POST_VARS

I’m trying to update my PHP version to 5.6. However, using a plugin to check if that is possible, it says something like this:

As I know, that vars are removed in PHP v5.4 and we should be using $_POST.

I can make the change but if you push a version up then all my changes will be lost. Could you please upload the code to github so I (and possibly others) can make pull requests to this plugin?

Thank you!!
