If you are leading a team or company, then it is also possible to support Xdebug through a subscription. Native Xdebug Path Mapping I have started on the Native Xdebug Path Mapping project. As this is a separately funded project, I don't classify the hours that I worked on this in "Xdebug Hours". Instead, the testing framework tests the return values and generated structures directly, without PHP having to be involved. Beyond the testing framework, I have also made a start on the parser itself.
