Small note: the function resolves symbolic links. That is, if the link is created by user 999 and maps to a file owned by user 666, this function returns 666 :(

Remember to use if(fileowner(...) === FALSE) instead of if(!fileowner()) or if(fileowner() == FLASE) because if the owner was "root" it would return 0.

This function will always return 0 on Windows, because Windows does not support numeric user IDs.
