In Xdebug 2.1 there is a new option called xdebug.collect_assignments
[1]. Whether it can show the modification depends on how the global is
used. If it's used like $GLOBALS['key'] it would show up, but if you use
"global $key" then it is trickier as that would just make a reference
and only $key = will show up in the function traces.
